Effects of polymers on the cavitating flow around a cylinder: A large-scale molecular dynamics analysis

The cavitation flow of linear-polymer solutions around a cylinder is studied by performing large-scale molecular dynamics simulation. addition polymer chains remarkably suppresses the cavitation. polymers are stretched into linear shape near and entrained in vortex behind cylinder. As stretch, elongational viscosity increases, which formation. Furthermore, exhibit an entropic elasticity owing to stretching. This elastic energy increases local temperature, inhibits inception. These effects result dramatic suppression
