HEAT TRANSFER OF CYLINDER BEING COAXIAL WITH EFFECTIVE VOLUME OF CYCLONE CHAMBER WITH DOUBLE ASYMMETRICAL GAS INLET
Abstract
Investigation of heat transfer on the surface of a circular cylinder with asymmetrical gas inlet conditions in a cyclone chamber has been executed while changing an aggregate state of heating agent that is slightly superheated steam which is supplied into the cylinder-calorimeter. Air has been supplied into the cyclone chamber from two diametrically opposite sides through the slots in the top and bottom parts of the transverse planes on a relative distance from the ends which is equal to 0,5Dк. Unbalanced stream input into the chamber has been created due to varying the inlet relative area in its bottom part. The obtained data have been processed in the form of dependence of the average Nusselt number on Re number and a parameter characterizing the asymmetry of the inlet.
