In [[fluid mechanics]], a '''homentropic''' flow has uniform and constant [[entropy]]. It distinguishes itself from an [[Isentropic process|isentropic or particle isentropic flow]], where the entropy level of each fluid particle does not change with time, but may vary from particle to particle.  This means that a homentropic flow is necessarily isentropic, but an isentropic flow need not be homentropic.

A homentropic and [[perfect gas]] is an example of a [[barotropic fluid]] where the pressure and density are related by<math display="block">P(\rho) = K\rho^\gamma,</math>where <math display="inline">K</math> is a constant.<ref>{{cite journal |arxiv=1604.03835 |first=Gordon |last=Ogilvie |author-link= |title=Astrophysical fluid dynamics |journal=Journal of Plasma Physics |date=n.d.|volume=82 |issue=3 |doi=10.1017/S0022377816000489 |bibcode=2016JPlPh..82c2001O |s2cid=55736672 }}</ref> <references />
