Compressibility Effects of Flow between Parallel Plates

1 Compressibility Effects of Flow between Parallel Plates 

p and u are the channel average density and the velocity, respectively. The momentum equation in streamwise direction can be written as 

Dividing both sides of this equation by QiPq), we get 

Using m = PqUqH, the last term on the right-hand side of this equation is pQU-ohitlQ — Uj) Pol O i 

It may be noted that we have used the equation of state and conservation of mass for the simplification of equation (3.56) given as
