The drag coefficient of a runner and its heat transfer coefficient are calculated by modeling the runner and its gridding in the Gambit software, and then analyzing and solving fluid flow around the model in the Fluent software. The above coefficient or coefficients are compared with the previous values obtained and the accuracy of the method performed in the calculation above is determined. The above coefficients are calculated for six different velocities and finally, a relation/equation is obtained for the heat transfer coefficient of the runner and a specific number for its drag coefficient.
