Inverse conduction algorithmHeat transfer coefficientA method of estimating a heat transfer coefficient at the surface of a solid body is described. Knowing the ambient temperature and the temperature history at an inner point (points) of the body, the heat transfer coefficient is computed. The ...
7、 Nusselt number, viewed as the dimensionless convection heat transfer coefficient is defined as:Nu=hLckWhere k is the thermal conductivity of the fluid and Lc is the characteristic length. The physical significance means the heat transfer ratio of convection to conduction. For Nu=1, the heat...
碳传递系数 carbon mass transfer coefficient 单位时间(秒)内气氛传递到工件表面单位面枳的碳最(碳通量)与气氛碳势和工件表面含碳量(碳钢)之间的差值之比。 退碳decarburizing 有意使工件表面降碳的化学热处理。 复碳carbon restoration 工件因某种原因脱碳后,为恢复初始碳含量而进行的渗碳。 过渗碳 overcarburizing...
Uo is the overall heat transfer coefficient between the water surface and the environment given as:[9]Uo=hw·Tg−Ta/Tg−Ts+hrgsand the surface area Ar is the ratio of cover area Ag to the free horizontal surface area of the salt water in the basin Aw:[10]Ar=Ag/Aw. ...
