摘要
本文开发了多点非线性估计方法计算铸件/冷铁界面换热系数的程序。通过温度、界面气隙的测试和数值计算的方法研究了界面热交换的特征和影响因素。
A more accurate method has been developed which may be called “improved nonlinear estimation method” for calculating the interfacial heat transfer coe- fficient between metal and chill.The nature of interracial heat transfer and factors influencing it have been studied by means of temperature,air gap mea- surements and numerical computation.
