Evaluation of heat transfer augmentation for laminar flow within parallel plate channel with staggered baffles

A numerical analysis is performed to calculate pressure drop for laminar flow within two parallel plates with a series of staggered baffles, and heat transfer augmentation of the channel is evaluated by applying the authors' previous numerical result of heat transfer. The results are presented in ranges of both Reynolds numbers and Prandtl numbers from 1 to 10² for nine geometric configurations. It is found that a channel with low height baffle becomes a useful heat exchanger for fluids having high Prandtl number values.
