An experimental study of friction factors and mixed convection in the thermal entrance region of vertically narrow, horizontal rectangular channels for different heating conditions and aspect ratios

Creator:: Hong, Seung-Ho
Abstract:: Heat transfer and fluid mechanical behavior of water flowing horizontally in vertically-narrow rectangular channels was studied in this work. Friction factor and Nusselt number variations were determined experimentally for four different wall heating conditions, and for aspect ratios(height to width) of 5, 4, 3, 2, and 1. Wall heating conditions...
