边缘冷却的效果是解决在通量管和通量通道。本文给出了一种新的矩形热流通道边冷散热阻力的解析解。该解包含许多极限情况，包括先前发表的绝热边解。与边缘冷却和绝热边缘的圆形通量管进行了比较。简单的关系，边缘冷却系统，以评估边缘冷却的重要性。这说明了当边缘冷却条件改变或没有影响时计算或重新计算特征值的问题。结果表明，这种简单的方法提供了很好的结果为广泛的无量纲参数。
The effect of edge cooling is addressed in flux tubes and flux channels. A new analytical solution is obtained for thermal spreading resistance in a rectangular flux channel with edge cooling. This solution contains many limiting cases, including a previously published solution for adiabatic edges. Comparisons are made with the circular flux tube with edge cooling and with adiabatic edges. Simple relationships are developed for edge cooled systems to assess the importance of edge cooling. This alleviates the issue of computing or recomputing eigenvalues when the edge cooling conditions change or have no impact. It is shown that this simple approach provides good results for a wide range of dimensionless parameters.
