SIMULATION OF FLUID MOTION IN A TUBES OF DIFFERENT CROSS-SECTIONS

Анотація

The geometry of heat exchange elements is a very important factor that significantly affects the parameters of convective heat transfer. Selection of optimal and rational geometric parameters of heat exchange elements, as a rule, is carried out experimentally. As a result of experimental research, a sample of significant factors and physical quantities are selected, which allow to determine the coefficients of the Nusselt criterion equations to determine the heat transfer parameters. The methodology described above is a rather complex, time-consuming and expensive process [1].
