Heat Transfer in Liquid Film over the Surface of a Rotating Disk Subjected to Impinging Jet

Research output: Book/ReportReport

Abstract

This work is theoretical analyses of heat transfer across
film a flowing over the surface of a rotating disk. This field has
wide industrial applications in Turbomachinery, chemical, and
food industries.
An analytical study is developed to investigate the heat transfer
characteristics in the liquid film due to jet impinging at the
center of the disk. A theoretical model is based on heat balance
and energy equations developed for a rotating disk heated by a
constant heat flux and the free surface are subjected to the
surrounding.
Local Nusselt number and temperature were found for different
selected parameters such as Prandtl number and Reynolds
number. Nusselt number obtained from the present model was
compared with that obtained by Thomas et al., and the
agreement between the results was acceptable.
