摘要

The article considers the forecasting of the increase in anomalous intensification of heat exchange on a surface with inclined grooves using numerical optimization methods. It was shown previously that anomalous intensification of separated flow and of heat exchange in inclined grooves with hemispherical ends is observed during the movement of water- and air-heat-carriers in structured channels. Optimization of the groove shape in plan allows increasing the effect of anomalous intensification of heat emission from a heated structured surface. The optimization was carried out using a multi-objective genetic algorithm within the framework of numerical modeling based on the solution of the full Reynolds-averaged Navier–Stokes equations. A teardrop shape of an inclined groove is proposed which allows a significant increase in the intensity of heat exchange near a heated structured surface.
