Book Description
The free-convection flow of water in a narrow vertical enclosure, cooled at the top through a copper surface and open at the bottom to a heated reservoir, has been studied by means of a shadowgraph. It was found that there is no flow pattern which is steady with time, that is, no region of the enclosure is permanently a region of upflow or of downflow. Because of variations in the size of the various upflow and downflow regions arranged along the length of the enclosure at a given time, and because of changes with time, neither upflow regions nor downflow regions could be characterized by a definite size. The number of upflow and downflow regions varied with time.

Book Description
This study was undertaken to develop and demonstrate the validity of an analytical model for predicting the transient temperature response in honeycomb sandwich panels subjected to variable heat loads on one or both faces. A one-dimensional analysis was developed which employs the ordinary heat balance considering heat transfer through the panel by conduction, convection, and radiation. The finite (forward) difference technique is employed for solving the heat balance equations. Honeycomb panels of various materials, cell shapes, and dimensions were subjected to a variety of heat loads and their thermal responses were recorded. The predicted thermal responses for these panels, obtained with the analytical model, were in good agreement with the test data. (Author).
