Title of the articleCalculation of the lower suction from heat sources
Abstract.The problem of the required intensity of suction, trapping heat stream, rising above the heat source in the form of an extended half-cylinder is solved. Rising convective flow velocity at a point on the axis is equal to the velocity induced by the action drains. This upward flow slowed, turns and moves in the inverse direction. As a result of the interaction of the rising convective flow with the current, induced by the action of heat sinks on the closed recirculation zone– the dome is formed. The recirculation zone above the heat source is modeled by two vortices, suction – two point sinks. It is necessary to determine the ratio between the intensities of the vortices and sinks under which described flow can exist. If this ratio increases, the height of the dome reduces – the capture of the convective flow is excessive, with an increase in the dome collapses so a complete recovery does not occur. The flow is considered flat and potential. The analytical solution of the problem and geometrical dimensions of the dome were found.
Keywords.Bottom suction, heat source, flow, vortex, sink, strengths of vortices and sinks.
