本文讨论了在均匀自由流中加热到恒定温度的半无限大垂直平板上的边界层流动，分浮力对边界层发展起辅助作用和相反作用的两种情况。在前一种情况下，得到了两个级数解，其中一个在前缘附近有效，另一个渐近有效。一个精确的数值方法被用来描述在该系列是无效的区域的流动。在后一种情况下，在前缘附近得到一个有效的系列，并用数值方法将其扩展到附面层分离的点。
The boundary-layer flow over a semi-infinite vertical flat plate, heated to a constant temperature in a uniform free stream, is discussed in the two cases when the buoyancy forces aid and oppose the development of the boundary layer. In the former case, two series solutions are obtained, one of which is valid near the leading edge and the other is valid asymptotically. An accurate numerical method is used to describe the flow in the region where the series are not valid. In the latter case, a series, valid near the leading edge is obtained and it is extended by a numerical method to the point where the boundary layer is shown to separate.
