对流损失;
The Level-Set approach was adopted to deal with some factors such as deposited track, liquid/ vapor interface, which considered surface tension gradient ( the major driving forces for the melt flow), interface curvatures, buoyancy and convection heat loss.
通过水平集(level set)方法处理熔积轨迹、液/气界面等因素,考虑了熔体流动的主要驱动力表面张力梯度、表面曲率以及浮力等。
The model considered the influences of the mode of reactants supply, the chemical reaction in the combustion chamber, radiation and convection heat loss of the combustion chamber wall, as well as fluid density changes in the tailpipe on stable operation of pulse combustion.
该模型考虑了反应物的供给方式、燃烧室内的化学反应、燃烧室壁面辐射与对流传热损失以及尾管内流体的密度变化对脉动燃烧稳定运行的影响。
