Abstract
The cooling of compressed medium when passing through the set of ribbed tubular elements is numerically investigated. Numerical experiments are carried out with the model of viscous heat conductive turbulent compressed gas by the control volume method with application of different numerical schemes and algorithms. The process of convective heat exchange between the cold ribbed surface and the hot gas flow is studied as well as the heat conductance processes in tubular elements. After processing the obtained results recommendations are given on the arrangement of the set of ribbed tubular elements to provide the assigned temperature characteristics of the cooling system; and the engineering technique of evaluating the thermohydraulic parameters of the cooling system is developed.
