Jet Impingement Heat Transfer
 

Hello everyone,
I am doing a jet impingement problem using V2F Turbulence Model. Its been 2 week since I started this problem but still I am not able to get correct result. For validation I got correct results but for main case I am not getting maximum Nu number at stagnation point. In my results it comes max at r/D=0.50 .
Problem Description:
D=0.05 m
H/D=2 & R/D=6
Axis symmetry problem.
Inlet velocity & Temperature : 10 m/s , 2273 K
T.I And T.L.S at inlet= 5% & 3.5mm
Plate Wall at Constant temperature : 673 K
Pressure Inlet : 180 Bar , 2273 K
Pressure Outlet : 180 Bar , 2273 K
This problem is to simulate combustion inside large 2 stroke marine diesel engine.

Please help.. :)
