Application of Lattice Boltzmann Method in Microflow Field
摘要
Abstract
In order to explore the state of the microflow field for large heavy water-lubricated bearing, the micro-interface simplification model of the micro-convex body of water-lubricated bearing is established by using the meshless particle method-lattice boltzmann method. The fluid flow regime of the micro-convex body adjacent to the bearing surface is investigated, and the streamline distribution, pressure distribution, and vortices formed in micro-convex bodies are analyzed. The results show that this method is feasible to study the characteristics of the micro flow field of water-lubricated bearing. It provides a new idea for the dynamic characteristics simulation and microscopic mechanism research of the water-lubricated bearing, and some references for the research of water-lubrication bearing micro-interface.关键词
