Non-dimesionalised Euler Equations

November 26, 2007, 23:39

Plz can anyone mail me nondimensional form of the 2d Euler Equations???? I have one, but i can't figure out how sonic velocity and Temperature are non dimensionalised.

Thank You....!!!!!!!!!!!!!!!!!

For 2D axisymmetric flow

dU/dt + dF/dx + dG/dr = S

U = [rho, rho*u, rho*v, P/(Gamma - 1) + 0.5*rho*(u^2 + v^2)]Transpose

u = u'/a_e' P = P'/(rho_e'*a_e'^2) T = T'/(Gamma*T_e') rho = rho'/rho_e'

the '_e' are constant variables

Hope this helps
