Abstract: One-row dimple reliefs for heat transfer intensification in narrow channels are designed based on the use of oval dimples for laminar and turbulent air flows. A comparative analysis of heat transfer in a channel with $22$ one-row dimples and a periodic calculation module with one dimple under periodic boundary conditions at the flow-through boundaries is carried out. The focus is made on estimating the thermal and thermohydraulic effectivenesses of the channels under consideration.
