摘要
在传热过程分析研究中需要求解微分方程,而这些描述传热过程的微分方程在多数情况下无法获得解析解,只能利用数值方法求解。通过MatLab在若干导热过程实例中的应用,探讨稳态与动态传热过程中温度分布、传热量、热通量等参数的求解与分析方法。结果表明MatLab工具能够十分有效、快速、准确地求解稳态与动态传热微分方程,为传热过程的数值分析研究提供了一个强有力的工具。
Difference equations must be solved for studying on heat transfer. But these difference equations are not solved by analytical method and must be solved only by numerical method. The method of solution and analysis of temperature distribution, rate of heat transfer and heat flux was discussed by application of MatLab in several example of conduction. The results showed difference equations of steady state and unsteady state conduction may been solved by MatLab effectively, quickly and accurately. MatLab is a cogent tool for studying and analysis of heat transfer.
