Hi Everyone..
As a part of masters project, am doing flow analysis of axial micro turbine to evaluate pressure on blades.. my previous simulations resulted into singularity error while transferring result to FSI analysis.. i ve refined the mesh to fix this, which increased the mesh size now nearly 7 million elements. Which will occupy my computational resources and will eat lots of time than previous.
So i ve bn suggested to run the same with cyclic symmetry..
i am using 3d sliding mesh in fluent.. whether symmetry will work with that. ?
I am having 8 blades -symmetric- i have taken 1 full and 2 halves of adjacent blades for symmetric analysis. Is this correct way fr symmetry..
i am getting very low mass flow rate with same pressure in -pressure out bcs,, also i have not corrected pressures for symmetric analysis..
Kindly correct me where its going wrong. and share opinions to fix this.
Thanks in advance
Gowrav
