摘要
摩擦火花传热模型可看做是二维稳态边界层外掠球体的强制对流传热问题。由此给出摩擦火花传热的数学解析式,提出了防止产生摩擦火花的几点措施。
The model of heat conduction caused by friction spark can be regarded as forced convection heat conduction issue of grazing spheriform which is outside of planar stable state boundary layer, so the mathematics analytic formula is presented and a few measures for preventing friction spark.
