Abstract

Smoothed particle hydrodynamics (SPH) is a mashfree method in that the interpolation points are the free-moving particles themselves. Each particle represents a volume of the fleuid carrying the properties of that region along with them. The typical properties associated with each particle include the mass, velocity, temperature, pressure, internal energy and entropy change. While often more computationally demanding than grid-based methods developed for specific phenomena. Its advantages include improved stability and the ability to deal with high velocities and free surface flow. It exceptionally handles cases with deformable and irregular boundaries/interfaces and provides ease of adding additional effects. This work reports our results in using SPH to study the flow behaviour of transforming van der Walls fluid. Both hydrodynamic and thermodynamic quantities are examined using various SPH Kernels
