Abstract

Vortical intensification of heat transfer in microchannels with oval dimples is analyzed numerically. Using multiblock computational technologies, the separating laminar flow of air and heat transfer in a channel with a periodic one-row packet of dimples in the range of Reynolds numbers from 100 to 2500 is calculated. The thermohydraulic efficiency of the channel with oval dimples has been substantiated.
