VISUALIZATION OF HEAT TRANSFER

Get access DOI: 10.1615/IHTC7.4230
pages 91-102

Abstract

When heat transfer is associated to a convective fluid flow, visualization of heat transfer essentially employs the methods of flow visualization; three of them are reviewed here: (a) the heat transfer to a solid wall can be visualized by making use of the analogy between mass and heat transfer, or by a thermographic mapping of the solid surface. (b) Several kinds of tracer material are available to visualize the velocity field of convective fluid flows. (c) The density field associated to such flows can be made visible by optical methods; among them optical interferometers are an appropriate means to provide quantitative data of the density or of the temperature distribution.
