Abstract

A liquid film flowing over horizontal cylinders is of great importance as a high rate of heat transfer exists between the falling liquid film and the horizontal cylinders. The objective of this research is to use numerical predictions, following experimental verification, to study the flow field and heat transfer to better understand the heat transfer processes that occur in beds of irrigated horticultural produce. Also to refine the traditional methods of analysing heat transfer in threephase porous media by modelling the transport process in much finer detail. This objective relevant, to hydrocooler where warm produce is cooled directly by spraying it with chilled water, the process is known as hydrocooling. Other similar systems, is achieved by formulating the equations that govern heat transfer on the scale of the pieces of horticultural produce, and the spaces between them.
