Numerical Simulation of Fluid -Solid Coupling for Lubricating 011 Extrusion Process Between Cylinder and Piston with Micro -pits
凹坑表面活塞与缸套挤压润滑油的流固耦合数值模拟

On the condition of full lubrication test,Coupling Euler Lagrange(CEL) method was introduced to solve the extrusion process of lubricating oil between cylinder and piston with micro pits.Kinetics equation of lubricating oil was described with Navier-Stokes(N-S) equation in Euler coordinate system.Isotropic linear elastic equation in Lagrange coordinate system solved the piston-cylinder system.Penalty function method was adopted to transfer the physical parameters of solid to the fluid element,thus fluid-sol...
