abstract: in the study of compressible flows, the isentropic model was often used to replace the more complicated full system when the entropy is near a constant. this is based on the expectation that the corresponding isentropic model is a good approximation to the full system when the entropy is sufficiently close to the constant. we will discuss the mathematical justification of isentropic approximation in euler flows and in navier-stokes-fourier flows. this is based on the joint work with y. chen, j. jia, and l. tong.
