I'm trying to estimate the drag force of a simple sphereusing FloWorks 2008. The sphere is 0.15m in diameter and the fluidis water at 278K moving at 1ms-1.
The tutorial about cylinder drag says that you should calculate the'Component of Force' along a specified axis. If I do this for asphere, the value is approximately half that which is expected(I've done the calculation by hand). If, however, you calculate the'Normal Component of Force' as well as the 'Component of Force' andadd the two together, you get the right answer.
Why do I have to calculate both these components to get the rightanswer when the tutorial only specifies one of them?SolidworksFlow Simulation
