Effect of VCS Scheme for Prediction of Impact Pressure to Vertical Wall of Dam-Break Flow in MPS-Based Simulation

Key Points

• The aim is to investigate the applicability of the VCS method to the MPS framework for reducing pressure noise in dam-break flow simulations.
• Applied VCS method in MPS-based simulations.
• Conducted droplet oscillation calculations to assess energy conservation properties.
• Performed impact pressure calculations during dam break flow on vertical walls.
• VCS method did not adversely affect energy conservation.
• Significant reduction in large pressure fluctuations at wall impact.
• Intermittent high-frequency noise was effectively suppressed by using smaller particle sizes.
