Negative Lift from flow over a vane using profile inlet boundary condition?

I did an analysis in fluent for a flow over vanes with a constant inlet boundary condition (Mass flowrate). With this, I got positive lift, drag and moment. Thereafter, I perform the analysis...

How do I define a non constant (velocity profile) inlet boundary condition in fluent simulation?

I am simulating flow over vanes and the air flow is from a propeller which the flow velocity varies across the length of the prop. The velocity is zero at the tip then increases to maximum at the...

CFD convergence problem: My simulation monitored parameters does not converge completely. Can anyone tell me why?

In my simulation of analyzing the effect of vane deflection of air pushed by a propeller in a shroud, I set up some variables (like cd, cl, force, moment) to monitor. After running up to 10000...

I want to analyse flow over vanes in a shroud but having issues with the meshing. Can someone please assist me in tackling this?

I want to analyse flow over vanes in a shroud but having issues with the meshing. My mesh either fails or very poor quality whenever I add inflation. The vanes are like wing shape. The inflation...

I am analysing flow over a wing in fluent but the lift coefficient is reducing instead of increasing.

I am analysing flow over wing but I found out that at low angle of attack between 0 and 10, the lift coefficient is reducing instead of it increasing with angle of attack while the drag...
