本文描述由一个局部内热源和外部加热同时作用引起的封闭空腔内非稳态、二维、层流自然对流换热的数值分析结果。
Numerical analysis is made for the unsteady and steady, two-dimensional laminar natural convection in an enclosure caused simultaneously by the external heating and a local internal heat source.
过大的加热宽度对局部热处理应力释放的作用不大。
Excessive wide heated band width appears ineffective to further reduce the residual stress.
