Comments on “Aerothermodynamic Effects of Controlled Heat Release Within the Hypersonic Shock Layer Around a Large Angle Blunt Cone” [phys. Fluids 30, 106103 (2018)]

Authors: Anbuselvan K.K.N.
Comments: 4 Pages.

Recently, Deep and Jagadeesh published a paper on understanding the aerothermodynamic effects of chromium coating over a large angle blunt cone test model at hypersonic flow conditions. The article concludes that the heat-flux at stagnation point increases by 25.6%, the temperature at stagnation region increases by 5%, and the shock stand-off distance increases by 17% with chromium coating. These findings appear to be ambiguous due to inconsistencies in the manner of calculating the free-stream values, the inappropriate use of measurement techniques and incorrect analysis of experimental data which have been elucidated in this comments.

Comments on “Aerodynamic Drag Reduction by Heat Addition Into the Shock Layer for a Large Angle Blunt Cone in Hypersonic Flow” [physics of Fluids 20, 081703 (2008)]

Authors: Anbuselvan K.K.N.
Comments: 1 Page.

The article1 showed a 47% drag reduction and 18% increase in shock stand-off distance with chromium coated surface whereas A.M. Tahsini2 performed numerical simulations of Kulkarni et al.1 work and found a large discrepancy (>50%) with the experimental results. The reason for the discrepancy is found in this comments to be improper data analysis of the experimental drag signals.

Magnetism-Driven Thermal Expansion

Authors: George Rajna
Comments: 43 Pages.

Computers, cell phones and other devices are built from many small parts and components that are prone to poor performance and damage caused by overheating. [26] An international team of researchers has measured a quantum power increase in a quantum boost engine for the first time. [25] Now, researchers in the UK and Israel have created miniscule engines within a block of synthetic diamond, and have shown that electronic superposition can boost their power beyond that of classical devices.

The Fire Theory

Authors: Adham Ahmed Mohamed Ahmed
Comments: 1 Page. ty

When you burn fire you have fire if you let it into space the fire would fade out and diminish because there are particles in space now lets assume that the lit fire is in absolute space space that has no particles in it then the fire would keep burning forever in fact it will grow as it burn the material it burns it burns now since fire is an electromagnetic wave we could say that the particles static electricity polarities(from particles)is the one that make the fire fade away but that’s not important the thing that is important is that if fire is attracted to the polarities without absorbtion its own polarity(positive polarity) will not be absorbed by electrons but rather would push the positive polarities of protons in other way since a fast moving fire would push other materials now lets study electrons and how fire spins around it(makes it jiggle as heat) and afterwards its absorbed by the electrons then remitted but lets study how the electron jumps from one level to the other way some of the energy of fire is transmitted into other colors of fire its probably because fire is not absorbed(partially) at all its reproduced by the electron by other colors with different intensities due to several electrons in all orbits but lets study how do several electron change the color of fire after its absorbed then reproduced it seems like the fire is absorbed several times and then produced and as some of the fire is absorbed at one level of electrons inside the atom it needs to pass another level of electrons this leads to the dispertion of fire(due to fire jiggling around electrons) and producing several colors from each electron now lets study explosion explosion happens best and strongest when fire keeps pushing with its polarity the portons the more precise the on hit of photons with proton for the most time (that you can do the on hit forever) without deflection of photons from protons the more you could reach the speed of light with bigger masses you need precision and continued result from precision a continued push to achieve speeds of light for this to happen you need to shoot burning fires away from electrons and onto protons to do this you have to shoot fire at very high speeds and very small amounts timed to intervals and the machine that hurls fire should be very lit very near to the pushed rocket and also you should shoot fire after fire so that the its produced very near to each other and that fire is very small in size but large in magnitude so that they push each other with a fire inducer and also you could make the amount of fire getting out of the rocket much less than the one pushing the fire by burning up fire from one side successively or even two sides if possible

The Mass Occupation Gravitational Theory

Authors: Adham Ahmed Mohamed Ahmed
Comments: 1 Page. ty

Imagine that you have a heave mass this mass occupies space and then you have a heavier mass of the same volume of the first heavy mass imagine that you increase the energy of the two masses the two masses thus increase in mass per volume ratio and thus increase gravitation you can measure mass to volume ratio gravitational force by getting a light element like hydrogen and a heavier mass such as the heaviest nuclear element and fill a volume(maybe a sphere) totally and fully with both of the two elements separately and each and heat each sphere to the point the element accept no more heat then measure the gravitational force of each of the two volumes with heated balls of similar elements to the point that the balls and the heated heavy element spheres are of G^(1/2) or of root of G

Coffee-Based Solar Absorption

Authors: George Rajna
Comments: 43 Pages.

Solar energy is one of the most promising resources to help reduce fossil fuel consumption and mitigate greenhouse gas emissions to power a sustainable future. [24] In the latest wrinkle to be discovered in cubic boron arsenide, the unusual material contradicts the traditional rules that govern heat conduction, according to a new report by Boston College researchers in today's edition of the journal Nature Communications. [23] Beyond the beauty of this phenomenon, which connects heating processes to topology through an elegant quantization law, the results reported in this work designate heating measurements as a powerful and universal probe for exotic states of matter.

Solar Cells Buttering Bread

Authors: George Rajna
Comments: 64 Pages.

"This means that we now have a method for the production of high-quality films for perovskite solar cells using an industrially scalable technique." [40] Organic electronics have the potential to revolutionize technology with their high cost-efficiency and versatility compared with more commonly used inorganic electronics. [39] By using an infrared laser beam to induce a phenomenon known as an electron avalanche breakdown near the material, the new technique is able to detect shielded material from a distance. [38] The light scattered by plasmonic nanoparticles is useful, but some of it gets lost at the surface and scientists are now starting to figure out why. [37] In a new review, researchers have described the fundamental physics that causes magnetoelectricity from a theoretical viewpoint. [36] Physicists at EPFL propose a new "quantum simulator": a laser-based device that can be used to study a wide range of quantum systems. [35] The DESY accelerator facility in Hamburg, Germany, goes on for miles to host a particle making kilometer-long laps at almost the speed of light. Now researchers have shrunk such a facility to the size of a computer chip. [34] University of Michigan physicists have led the development of a device the size of a match head that can bend light inside a crystal to generate synchrotron radiation in a lab. [33] A new advance by researchers at MIT could make it possible to produce tiny spectrometers that are just as accurate and powerful but could be mass produced using standard chip-making processes. [32] Scientists from the Department of Energy's SLAC National Accelerator Laboratory and the Massachusetts Institute of Technology have demonstrated a surprisingly simple way of flipping a material from one state into another, and then back again, with single flashes of laser light. [31] Materials scientists at Duke University computationally predicted the electrical and optical properties of semiconductors made from extended organic molecules sandwiched by inorganic structures.

Thermodynamics Super Efficiency

Authors: Jose Iraides Belandria
Comments: 8 Pages.

This article shows a surprising prediction of the global formulation of the second law of thermodynamics that suggests the hypothetical existence of super-efficient thermodynamics processes. Such processes, according to the local formulation of the second law of thermodynamics, may occur as a consequence of an internal entropy coupling between the different systems that make up the universe of the process. In this way, the heuristic combination of the aforementioned formulations predicts the theoretical existence of an operation zone where thermodynamic processes can produce more mechanical work than conventional reversible operations.
