Convection Heat Transfer Coefficient - an overview - ScienceDirect

WebNusselt number is equal to the dimensionless temperature gradient at the surface, and it provides a measure of the convection heat transfer occurring at the surface. The Nusselt number is named after a German engineer Wilhelm Nusselt. The conductive component is measured under the same conditions as the heat convection but with stagnant fluid. Convection cooling is sometimes said to be governed by "Newton's law of cooling." When the heat transfer coefficient is independent, or relatively independent, of the temperature difference between object and environment, Newton's law is followed. The law holds well for forced air and pumped liquid cooling, where the fluid velocity does not rise with increasing temperature difference. Newton's law is most closely obeyed in purely conduction-type cooling. However, th… WebAboutTranscript. There are three forms of thermal energy transfer: conduction, convection, and radiation.
