Theoretical basis for the expansion of an ideal gas in the potential field of a radial turbine
https://doi.org/10.15518/isjaee.2023.10.162-167
Abstract
It is shown that the plane-parallel motion of a gas in a potential field is described using shock adiabatics, and if the stationary gas flow in the field is accompanied by compression, then the entropy increases. The reverse process of gas expansion in a potential field is accompanied by a decrease in entropy. This explains the low efficiency of centrifugal gas compressors and the high efficiency of turbines (expanders) with radial gas motion in the field of a non-inertial (rotating) reference frame. The excessive conversion of internal gas energy into kinetic energy during centripetal motion in a vortex can explain the stability of natural vortices, such as tornadoes, cyclones and cosmic jets.
