直壁喷管
Basset force and virtual mass force are on the same magnitude as Stokes force and are important for the motion of abrasive particles during the initial phase of particle movement in the convergent section and straight tube section of the nozzle.
当磨料颗粒在喷嘴的收缩段和直柱段中运动时,磨料颗粒所受的Basset力、虚拟质量力与Stokes力处于同一量级,对磨料颗粒的运动影响很大,不可忽略;
