Comparative Study between Heat Transfer through Laminar Flow and Turbulent Flow

Pranit M Patil, Amol P Yadav, Dr. PA Patil

A common situation encountered by an engineer is heat transfer to fluid flowing through a tube. This can occur in heat exchangers, boilers, condensers, evaporators, and a host of other process equipment. The study of heat transfer can be done either in laminar flow or in turbulent flow. Both conditions show different performance characteristics of the heat transfer. In this paper, comparative study of heat transfer in both conditions is done. Under turbulent flow conditions, the increase in heat transfer rate is more significant than that under laminar flow conditions. This is due to the increase in the Reynolds number of the flowing fluid in turbulent flow. The turbulent effects become a dominant factor over secondary flow at higher Reynolds number.
