Dear, everyone..
I am doing a numerical investigation of unsteady heat transfer in a Newtonian fluid occupying a square cavity. I solved numerically using HSMAC(Highly Simplified Marker and Cell) finite difference approach as the governing dimensionless equation. The fluid flow is simulated with a heating on vertical side (left) wall and a cooling on vertical side (right) wall. The program has been exist, so I only studied the code of program to get the data and it has been done. but my problem is the data are dimensionless, so need I return those data into dimensional term before drawing??
for example: Vx= nondimensional of velocity in x-axis, and I already got the values.
v = dimensional of velocity in x-axis, where Vx = v/V*
so that in the equation, I defined v = Vx . V*.
where, V*= α/L , α = thermal diffusivity (m2/s), L= Height of enclosure in x-axis (m)
So, need I change the data to get the dimensional parameter as like v,P,T before plotting?? need I change the Vx to v ?
hopefully someone can help me..
thank you.
