摘要：A common situation encountered by an engineer is heat transfer to fluid flowing through a tube. Thiscan occur in heat exchangers, boilers, condensers, evaporators, and a host of other process equipment. The study ofheat transfer can be done either in laminar flow or in turbulent flow. Both conditions show different performancecharacteristics of the heat transfer. In this paper, comparative study of heat transfer in both conditions is done. Underturbulent 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 becomea dominant factor over secondary flow at higher Reynolds number.
