Summary
The objectives of this research are two-fold; one is to carry out an extensive experimental investigation of pressure drop and heat transfer for internally enhanced passages in laminar, transitional and turbulent flow. The laminar and transition regions have received very meager treatment in the past. In addition to the effects of Reynolds number and the geometric characteristics of the enhanced surfaces, a comprehensive investigation of the effect of fluid properties, which is usually expressed in terms of the Prandtl number, is one of the central features of this research program. The influence of Prandtl number on friction and heat transfer is undoubtedly the least understood because only a handful of studies considered more than one fluid. Also, there has been no consistent investigation of the Prandtl number effect for laminar or transitional flow. The second objective is to develop a general method that will aid data correlation and prediction which, in turn, will provide better understanding friction and heat transfer characteristics for smooth and enhanced passage. More specifically, the aim is to validate the frictional law of corresponding states using the present experimental data.
