Abstract:Modified equations for surface tension are derived by modifying normal and curvature with corrected smoothed particle method(CSPM).It is based on smoothed particle hydrodynamics(SPH) method with surface tension proposed by Morris.Both Morris and our method are tested via a semicircular problem.Factors that affect accuracy are investigated including surface definition,normal and curvature calculation.Smoothed length in curvature calculation is also confirmed reasonable.Furthermore,formation of a liquid drop ...
Keywords:smoothed particle hydrodynamics  surface tension method  CSPM  CSF  curvature
