Abstract
The article discusses the methods for identifying the heat-hydraulic characteristics of the slotted channels of a complex profile in the case of laminar and transient modes of air flow. The identification of aerodynamic characteristics is carried out on the basis of a full-scale experiment. The working medium in the experiment is water. In the transition to dependencies for air, similarity theory is used. The study of heat transfer in the channel is carried out numerically. An effective method of approximation of the equations of mathematical transport models is proposed and a new algorithm for jointly solving transport equations is used. The solution of tasks on modeling air velocity and pressure is carried out iteratively. The obtained air velocity field allows us to determine the temperature field by a numerical method. According to the simulation results, criterion dependences are established for describing heat transfer.
