Investigation of particle motion in a rotatory flow field exposed to a forced vortex condition

To enhance the performance and service life of the operating instrument in the food production process, the purpose of this paper is to study particle motion in a forced vortex flow condition as a way of performance improvement. To solve the nonlinear equations of motion for the fine particle, a meshless Galerkin technique is applied. After declaring the proper accuracy of the results by comparison with existing research papers, the influences of some critical parameters on the particle movement have been examined. The radial part of the sphere velocity increases when the sphere size increases. However, this radial velocity is reduced by enhancing the sphere's initial velocity. For all situations, the sphere's velocity reduction is observed over time.
