Abstract
In this paper the infl uence of the curvature of the portion of the heat exchanger on heat exchange with the use of software systems Salome Meca and Code Saturne is numerically studied the verifi cation of the numerical model by comparing with experimental data of other researchers without taking into account heat exchange is made. The solution is held for an average fl ow rate equal to 11 m/s. To investigate the infl uence on heat transfer of the curvature of the channel carried out the construction of the computational domain in the form of the heat exchanger of the same length with diff erent turn radius. For discretization of the computational domain were used tetrahedral grids containing approximately 850 thousand of elements with local refi nement near the surface of the channel. As a result of simulation values of the fl ow temperature at the outlet of the channels are obtained. It is revealed that the design of heat exchanger channel, of course, aff ects the heat transfer, as well as data on the applicability of diff erent turbulence models for this type of task are collected.
