WebApr 4, 2024 · The reason I asked is to be able to find the drag/force for a particle moving along any direction. For instance, the plasma is at the origin of a Spherical polar Frame and pass through it at some radial distance, at ang co-latitude angle (theta) = 45degree and azimulth angle (phi) 45degree. How would I incorporate it in the drag equation? WebMar 1, 2013 · The corresponding equation for the drag coefficient is: (1) C D = D 1 / 2 ρ U 2 π a 2 = 24 R p, with Rp (= Ud / v) based on diameter ( d = 2a) and kinematic viscosity ( v = μ / ρ ). The equations of Stokes have a serious defect since they result in streamlines that are symmetrical before and after the sphere and hence show no wake.
