Current research

The current research emphasizes two main interlinked aspects of Smoothed Particles Hydrodynamics (SPH) method; namely addressing current shortcomings of the SPH technique which will be elaborated in the body of this research, and focusing on the development of SPH code to analyze a wide range of engineering flow problems.

The specific objectives of the current research are; (i) to implement a new improved boundary treatment method (developed by my current supervisor) on the simulation of bluff bodies with complex geometries such as flow over an airfoil and square obstacle, and (ii) to develop an incompressible multiphase SPH (IMSPH) algorithm to solve complex flow problems in various engineering fields such as polymer processing and biomedical applications.

Our current in-house weakly compressible and incompressible SPH codes will be further developed to simulate complex physics involving multiphase flow, non-Newtonian fluid flow with free surface, and fluid-solid interaction problems.
