I am currently involved in CFD simulation in textile manufacturing process particularly Relay nozzles.In relay nozzles the air blows out at high pressures of about 1-7 Bar.The complete simulation is carried out for 5 Bar.
As the geometry is very complex and takes millions of cells,we thought of other way for the simulation of other 6 pressure levels.We thought of simplifiying the geometry and appliying Momentum Source.
We tried to check this by comparing with the complete simulation of 5 BAr.,but observed that the momentum to be applied was 50 times the theoritical to get same velocity profile.
Please can anybody tell the reason behind this.?
