 Numerical Investigation of the Temperature Stratification The intensity of heat and mass transfer in devices based on the gas-dynamic temperature stratification, for example, in a supersonic pipe temperature stratification (in the Leontief’s pipe) is determined by the heat flow through the separation wall between subsonic and supersonic flows. This paper presents the mathematical modeling and numerical study of heat transfer in devices of gas-dynamic temperature stratification using passive stimulation techniques. The efficiency of heat pipes (HP) and the metal edges of the same configuration were researched. Mathematical modeling was performed using a mathematical model. The mathematical model includes differential equations that describe the motion and heat transfer in the boundary layer; equations for calculation of heat transfer processes in heat pipes; equations to calculate the heat flow between subsonic and supersonic flows in the device of gas-dynamic temperature stratification.It was found that the intensification of heat transfer devices based on the gas-dynamic temperature stratification (in the Leontief’s pipe) through the use of heat pipes is increasing up to 3 times. It was established that the use of heat pipes with a wick of material copper-water is more of using efficiency of heat pipes with the working material in the aluminum-acetone up to 1.05 ... 1.12 times.Mathematical modeling, numerical investigation, temperature stratification, intensification, heat pipes.

 Mathematical Modeling of the Temperature Stratification of the Modified Leontief Pipe With Heat Pipes Mathematical modeling and numerical investigation of the temperature stratification of the modified Leontief's pipe with heat pipes are conducted. A possibility of intensification of turbulent flows temperature stratification by means of using heat pipes is considered. It is identified that an application of heat pipes enables to increase the efficiency of the temperature stratification of up to three times.Mathematical modeling, numerical investigation, temperature stratification, heat pipes.
