E 3029 An Analytical Model for Non Linear Drag Forces Acting on a Sphere.
$50.00
This study presents an analytical model for nonlinear drag forces acting on a sphere and experimental verification for this model. In this model, we extend the particle equation of motion by incorporating additional force terms that are more general and theoretically feasible, including those arising from nonlinearities in Cauchy momentum equation, which is a more general form of Navier-Stokes equations. We analytically compute these forces and perform experimental verification, presenting a more comprehensive approach for particle dynamics.
