In house CFD code, FVHT has been used to solve the dimensionless form of the governing equations of heat transfer utilizing a hybrid TDMA method within a high-order finite volume approach. Enclosures with different aspect ratios (0.25 to 8) have been studied with different heat generation rates (6 to 14) in dimensionless form. The enclosures were in natural convection heat transfer mode filled with water (Pr = 6.2) having Rayleigh number from 10³ to 10⁶. Coupled entropy and energy equations in the presence of heat generation have been solved to obtain the iso-contours of the entropy within the enclosures. The mapping is beneficial in the selection of suitable aspect ratio of the cooling enclosure for minimum entropy generation at specified operating condition (heat generation and Rayleigh number). The numerical results of the total entropy generation as function of aspect ratio, Rayleigh number and heat generation are correlated.

在内部CFD代码中，FVHT已用于在高阶有限体积方法中使用混合TDMA方法来求解传热控制方程的无量纲形式。研究了具有不同长宽比（0.25到8）的外壳，它们以无因次形式具有不同的发热率（6到14）。外壳处于自然对流传热模式，其中充满了 瑞利数为10 ³至10 ^6的水（Pr = 6.2）。解决了在存在热量的情况下耦合的熵和能量方程以获得等值线-外壳内的熵轮廓。该映射有利于选择冷却箱的合适的长宽比，以在指定的工作条件下（热产生和瑞利数）最小地产生熵。将总熵产生的数值结果与长宽比，瑞利数和热量产生联系起来。
