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

Summary, in English

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.
