This study is focused on two critical issues of the flexible but compute-intensive particle-based CFD methods. Based on the particle-level momentum conservation, new source terms were derived for pressure Poisson equation. Besides the suppression of spurious pressure oscillations, the proposed approach is computationally efficient, consistent in time domain, has easily calibratable numerical parameter and simple implementation. Also, a new multiresolution technique based on border mapping was proposed to reduce the computational cost. Despite the overheads due to multiresolution processing and asymmetrical linear system, its feasibility and speed up capability were confirmed.
