Hey All,

I have had an issue figuring out the post-processing procedure required to find the thrust coefficient on a turbine blade. I thought that some of you might have dealt with the same post-processing before. The parameters of the turbine are as follows;

1- The turbine diameter is 4.5 m.
2- Hub radius 0.1m
3- Thickness of the actuator disk 0.14m

When I used plot over line across the center line of the wind turbine, I obtained the following figure;

My misinterpretation led me to use the following relation to obtain the thrust coefficient;

C_{t} = (p_{1}-p_{2})/0.5*\rho*V_{inf}^2

But, I finally figure out that I need to integrate the static pressure along the actuator disk. I used plot over line along the blade at a point above the hub till the tip of the blade. The coordinates are;

{0.0624, 0, 0} and {0.0625, 3, 0} The file of this post-processing data.xlsx

I have got the magnitude volume force as well as the position of each one. However, I don't exactly know what I do next. Which values should we take for the post-processing since I ran the case till 4000 iteration. Should I take the last iteration for the calculations of the thrust coefficient? What values do I need to use in order to find the the thrust? Has anybody experienced the same issue? Any guidance to achieve thrust...

Best,

If anybody is working on the same problem and having issues, contact me. The problem has been solved.

Thank you,

Hi @tareqkh,
I am using tidal turbine simulation using Virtual Blade Model code in ANSYS Fluent. I have to find out thrust coefficient on turbine. Can you please help me calculating in CFD Post?
Many thanks.
