Explanations:
Lower h has higher pressure coefficient loss. The fluid need to flow through constricted region which increase the frictional losses as compared with the flow through bigger h?
Evaluate the current progress
1. Model and validate a simple 180 degree turn over two baffles:
Create fully second order accurate model (done)
Perform mesh sensitivity analysis (using coarse, medium and fine meshes) (done)
Model the baffles using alternate Turbulence models (K-e Standard, K-e Realizable, K-w)
Analyze the effects of changing the baffle clearance height (done. increase height = decrease in pressure drop)
Understand and analyze the relationship between Strain Rate, Energy Dissipation and Kinematic Viscosity
Create a flexible mesh that uses parametrization to easily change geometry dimensions
Analyze the effect of the Reynolds Number on the results
Analyze the sensitivity of the model to convergence residuals (done)
