SIMULATION OF HEAT TRANSFER IN CHANNELS WITH CHAOTICALLY PACKED PACKAGE CONSIDERING DAMPING TURBULENCE THE BOUNDARY LAYER
This article describes how to use the model of turbulent boundary layer on the basis, of which to obtain an equation for calculating the average heat transfer coefficient. The model allows to take into account the flow of heat transfer in the channels filled with chaotic packed package, taking into account the damping of turbulence in the boundary layer. Are given expression and the calculations of the Nusselt numbers for the smooth surface of the pipe and the channel filled with chaotic packed package. As shown expressions constructed plots of Nusselt number on the Reynolds number (motion mode) for a smooth surface of the pipe and the channel filled with chaotic packed package. Displaying agreement between the calculated data Nusselt numbers on the submitted expressions and experimental data and other expressions. These expressions are recommended for practical calculations.
