Effects of gas-liquid phase transitions on soundwave propagation: A molecular dynamics study
Yuta Asano, Hiroshi Watanabe, Hiroshi Noguchi
To understand ultrasonic cavitation, it is imperative to analyze the effects of the gas-liquid phase transitions on soundwave propagation. Since current methods based on fluid dyna…
Effects of polymers on the cavitating flow around a cylinder: A Large-scale molecular dynamics analysis
Yuta Asano, Hiroshi Watanabe, Hiroshi Noguchi
The cavitation flow of linear-polymer solutions around a cylinder is studied by performing a large-scale molecular dynamics simulation. The addition of polymer chains remarkably su…
Molecular Dynamics Simulation of Soundwave Propagation in a Simple Fluid
Yuta Asano, Hiroshi Watanabe, Hiroshi Noguchi
A molecular dynamics (MD) simulation was performed to study the propagation of soundwaves in a fluid. Soundwaves are generated by a sinusoidally oscillating wall and annihilated by…
Effects of Cavitation on Karman Vortex Behind Circular-Cylinder Arrays
Yuta Asano, Hiroshi Watanabe, Hiroshi Noguchi
The effects of cavitation on the flow around a circular-cylinder array are studied by using a molecular dynamics simulation. Cavitation significantly affects on vortex shedding cha…
Finite-Size Effects on Karman Vortex in Molecular Dynamics Simulation
Yuta Asano, Hiroshi Watanabe, Hiroshi Noguchi
The characteristics of the Karman vortex generated by a molecular dynamics (MD) simulation exhibit strong finite-size effects, and MD can only reproduce the experimental results qu…
