 April 11, 2016, 11:38 How to calcuate the thust on a wind turbine? #1 Senior Member     Khamlaj Join Date: Nov 2010 Location: United States Posts: 198 Rep Power: 8 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; 10msVP.jpg 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,
