Abstracts:
Purpose is to study the effect of constructive and mode characteristics on the aerodynamics and heat transfer in the annular channels of cyclone recuperators. Researches carried out by physical and numerical modeling. Distribution of the averaged and pulsation velocity values investigated a two-beam laser Doppler anemometer manufactured by «Dantec Measurement Technology A/S». Metal steam calorimeters partitioned working volumes were used as surfaces of a channel in the study of heat transfer. The results of numerical simulations obtained with the program complex ANSYS-CFX. The proposed formulas can be used in the calculation of aerodynamic and thermal recuperative devices containing annular channels with swirling of heat carrier. |
