As technology advances, increasingly large computing power is being packed into increasingly small devices, bringing with it an increased amount of heat produced.  Cooling of electronic systems has thus become a key concern, both in terms of performance optimization and to reduce the amount of energy necessary to maintain these conditions.

PHOENICS在处理密闭空间中的热传递方面非常适用，而传统湍流模型的精度则低于PHOENICS的LVEL模型，因此，CFD现在被广泛用于对电子系统运行的预测和增强。
