Decided on the single bend. Use h = 1.5w and compare with h = 1w
w = baffle spacing
For h = 1.5:
Get Pressure Pressure coefficient loss of 3 across the bend
Lots of stagnant flow at the bottom corner
Yplus at wall less than 5
For For h = 1;
Pressure coefficient loss of 3.21 across the bend
Yplus less than 5
...
Analyze the sensitivity of the model to convergence residuals (done)
Change the velocity inlet to 0.5 m/s to check the Reynold's number effect. We see that the pressure difference is about the same delCp = 3.04;
