Type of article: Article

Summary

MEASUREMENTS OF THE HEAT TRANSFER BY NATURAL CONVECTION FROM ISOTHERMAL BODIES TO AIR ARE REPORTED AND COMPARED TO THE PREDICTIONS OF THE METHOD PROPOSED BY RAITHBY AND HOLLANDS. THE BODIES TESTED WERE THE CUBE IN VARIOUS ORIENTATIONS AND A BODY CONSISTING OF TWO TOUCHING SPHERES. THE EXPERIMENTAL METHOD INCORPORATED MEASURING THE HEAT TRANSFER BY THE TRANSIENT METHOD AND VARYING THE RAYLEIGH NUMBER BY VARYING THE PRESSURE. THE PREDICTIONS AGREED WITH THE MEASUREMENTS TO WITHIN AN AVERAGE ERROR OF ABOUT 3%.
