Mr. Sainath
I have tried the same simulation to check the initial guess by setting boundary condition as total pressure inlet and static pressure outlet. But it is also stopped for IGV 30 deg...

Mr. Sainath,
I am not clearly understood that why the simulation getting stopped while working on the mass flowrate above 52.35 kg/s at IGV 30 deg and more than that? I don't know why it is...

Hi Sainath,
Thank you. So you have given the value of pressure in inch of water column and volume flowrate in cfm. From your results, I have a doubt that the fan will not operate the flow...

Mr. Sainath,
Thank you so much for giving the details. You were right. I entered the details about the width of blade at ID and OD by mistake.
I have some difficulty in...

There is no recirculation at inlet. So I changed boundary condition as you suggested to check. It is also getting diverged and stopped.


Thank you for your suggestion. My aim is to generate...

Hello Glenn,
Thank you. The flow is incompressible and isothermal flow. The pressure ratio is not much high so that it is considered as incompressible flow in fan (given as best practices...

Thank you to reply sainath. Yes, I am doing it as Steady case. I have noticed that for inclination 15 deg there is no kind of problem happened for max mass flow. But, using 30 deg as well 60 deg...

Fan simulation divergence

Dear all,
I am doing FD fan simulation in Ansys 13 (domain has four individual part mesh). The aim of project is to develop the performance curve for different position of Inlet Guide Vane (...
