I have a question regarding the implementation of isothermal no slip wall boundary condition. I am using ghost points at (i+1) to generate a wall at i + 1/2.

u_i = - u_i+1
v_i = - v_i+1

rho_i = rho_i+1
P_i = P_i+1

T_i = ?

I guess it will be a constant and specify a value for your temperature.

For example you can use Ti=60F

If you follow your logic for other variables, you should choose T_(i+1) so that

(T_i + T_(i+1))/2 = Twall

You cannot of course specify density, pressure and temperature. You must choose only two of them, perhaps, pressure and temperature.
