A correlation for the heat transfer coefficent in a rectangular passage containing protuberance
Abstract
An experimental investigation was carried out to determine the effect on the
convective heat transfer coefficient of protuberances in a rectangular passage.
A cross-flow compact type heat exchanger formed by several parallel spaced
plates including protuberances was tested by using water, glycol and air as a working
fluids. Heat transfer coefficient data was obtained by measuring mass flow-rate,
temperature and pressure drops across the heat exchanger.
Heat transfer characteristics are discussed and correlations for Nusselt number,
Colburn factor and friction factor have been obtained.
