“…Swirling flows are the result of giving rotational motion to the flow using an axial-blade swirler, by tangentially supplying fluid through one or more peripheral holes, through a scroll or a tangential-blade apparatus 19,26 . The swirling of the flow can also be done by rotating the channel for internal flows.…”

The work presents the study results of the flow swirling impact on the heat transfer of equilibrium dissociating dinitrogen tetroxide. It was shown that heat transfer intensifies with an increase in the swirling intensity, which leads to an increase in the Nusselt number. Heat transfer of the flow depends on the integral intensity of the swirl, as well as of the organizing rotation method in the flow. Turbulent disturbances under active effect arise in the flow, which leads to an increase in heat transfer coefficient. Centrifugal forces contribute to the weakening of turbulent heat transfer and a decrease in heat transfer under a conservative effect.

“…With the known inlet tangential velocity field the value of A, is determined as the maximum value of the product of the tangential velocity and the radius of its location which determines the approximption 2. The swirl number S, and the axial velocity distri' ution u(y, 0) are then determined by solving the coupled equations (1) and (9). The accuracy of the axial velocity profile thus obtained may be checked by computing the average velocity and Reynolds number and comparing it with the actual value of the axial Reynolds number.…”
