Calculating the mass weighted total pressure is important for internal compressible problems, valves turbines and compressors. It is the desired variable for compressor companies to run sub models to optimize the inlet and outlet transition regions before and after the compression stages. Last week I meet with a compressor company that is happy using another CFD tool for the compressor stage design but only have 1 user. For the inlet and outlet transitions they are don’t more design work and feel that our CFD is a better fit and cost effective to roll out to 100 design engineers to right size new products to address new market needs. To fit into their workflow they need to know the Total Pressure at the outlet and map effectively to their current compressor CFD tool.
