考虑了最小容积率流体温度阶跃升高时交叉流换热器的瞬态分析。使用隐式中心有限差分法得到的预测。讨论了不同网格尺寸和时间步长对这些方法的影响。通过在代表性的数值范围内改变控制换热器瞬态响应的无量纲参数，进行了参数研究。© 2008 ASME
Transient analysis of a cross flow heat exchanger subjected to a step increase in temperature of the minimum capacity rate fluid was considered. Predictions obtained using an implicit central finite difference method were presented. The influence of varying grid sizes and time steps sizes on these approaches was addressed. A parametric study was conducted by varying the dimensionless parameters governing the transient response of heat exchanger over a representative range of values.© 2008 ASME
