A Novel and Efficient Method for Particle Locating and Advancing over Deforming, NonOrthogonal Mesh

ABSTRACT A method developed for particle locating and advancing in nonorthogonal curvilinear grids is presented. The method is uniformly applicable for deforming as well as fixed Eulerian grids. The method is equally applicable to coupled as well as uncoupled two-phase flows. Guidelines are presented on which the present and previous schemes are evaluated. The algorithm yields a generalized and efficient method and is being used in practical applications. The accuracy of the method is demonstrated by verifying with analytical and experimental data.
