Abstract

A study of convective flows, their evolution and formation mechanism has been carried out. Convective flows significantly affect the processes of heat transfer; therefore, the main attention is paid to the studying the role of secondary, small-scale structures in the boundary layer for the intensification of heat transfer. The features of the heat transfer process from a localized heat source in a cylindrical layer for various values of the Prandtl number, as well as the aspect ratios, are experimentally investigated. A laboratory study of the effect of convective rolls on the enhancement of the heat flux from the sea surface and the initiation of of rapid intensification process of tropical cyclones was carried out. An original approach has been implemented that combines measuring systems and a supercomputer. An approach for laboratory modeling of air flows and heat transfer processes on the scale of a metropolis has been proposed and tested.
