Abstract:
The present paper analyzes the particle movement in a rotational fluid flow domain to increase the efficiency of the system that is used to diminish damages coming from hazardous substances due to coal and petroleum ignition in the environmental issues. The nonlinear differential equations for the fine particle are solved utilizing the Optimal Homotopy Analysis Method. The capability of the proposed method to solve non-linear differential equations of particle transportation is observed to be reasonable. Eradicating the grid generation difficulties is the most significant advantageous feature of the proposed method. The particle location profile follows an increasing trend by the drag-to-inertia ratio and particle primary radius reduction. In addition, the particle location increases during the time in all various conditions. The particle's peripheral speed also decreases by boosting the particle's primary radius, but increases by raising the drag to inertia ratio.
