Reversed flow in Vertical axis wind turbine
I am working on my thesis that involves a 2D simulation of a Vertical axis wind turbine. I first made a rotating mesh surrounded by a stationary mesh in ICEM CFD and then applied periodicity in FLUENT. I got it rotating in Fluent but getting a reversed flow at the Pressure outlet. can anyone pls help me out with this problem? I tried to play with the backflow turbulent intensity and viscosity ratio but ended up with the same problem again.
The inner circle (Wind turbine with 3 airfoils) is Rotating at 1500 RPM counter-clockwise and outer rectangle is a stationary farfield. there are 2 zones Far_surface.1 (stationary zone) & rotor_surface.1 (rotating zone). operating pressure is set to be 1 atm.
I can even email my case/data file if somebody is interested to have a close look at the problem.
Thank you so much in advance
You have probably solved your problem long ago, but I thought I would make a suggestion anyway. I do 2d VAWT simulations in openfoam and for a 1m diameter turbine, I have to make the wind tunnel 20m x 20m or back pressure in the tunnel really affects the results. I'm sjh7132 on YouTube if you want to see some of my work.
Seen your work on youtube. good work.
Are you still in touch with OpenFOAM?
Seek your suggestions on implimenting VAWT model for blades of 1 meter length.
