文摘

The prior theories cannot explain the obtained experimental results of thermal effects in gases. It is difficult to offer any adequate explanation (prior theories) for the results of new experiments. The proposed concept of PGEWs adequately describes all of the experimental results. PGEWs arise in compressible fluids under conditions with a pressure gradient and sound waves. PGEWs transfer heat from the low pressure zone to a wall, located in the high-pressure zone.
