摘要

在涉及自然对流冷却问题的Biot数(1100至11000)范围内，给出了无限长圆柱体、无限平板和球体的瞬态热传导图。这些图表可以很容易地结合起来求解不同物体的温度历史，包括有限长度的圆柱体。在研究的Biot数范围内，有限圆柱体内微小温度梯度的分析及其简化解的准确性，即集总容量分析，在无限平板和无限圆柱体中给出了表格;这些解可以结合起来求解有限长度的圆柱体。

Transient heat conduction at low Biot numbers: A supplement to Heisler's charts

Charts for trasient heat conduction in a cylinder of infinite length, an infinite flat plate, and a sphere are presented for a range of Biot numbers ( $1100 to 11000$ ) relevant to problems which involve cooling by natural convection. These charts may be easily combined to solve for temperature histories of different bodies, including cylinders of finite length. Analyses of the minute temperature gradient within finite cylinders for the range of Biot numbers studied and the accuracy of a simplified solution, the lumped capacity analysis, are presented in tables for the infinite plate and infinite cylinder; these solutions can be combined to solve for cylinders of finite length.
