Second-Order Fluid Particle Scheme
Abstract
A new momentum and energy conservative fluid particle scheme (SOAP) having a second-order accuracy in the advection is developed. The scheme can be used in a nonuniformly spaced and/or moving grid system. The required particle numbers and calculation time are substantially reduced with less noise and numerical viscosity. The scheme is successfully extended to polar coordinate system without the difficulty of numerical centrifugal force.
