Parallel Flow Asymmetries in Heat Exchangers
Original language description
The effect of flow asymmetry was observed experimentally in vertical parallel channels of a continuous direct ohmic heater. While downward oriented flow is evenly distributed at isothermal conditions, flow-rate in parallel channels differs in the case ofheating due to the buoyancy effects. Three different configurations of parallel flow (with and without internal heating in channels) are analysed, giving critical values of Gr/Re or Ri=Gr/Re2 ensuring stable and even distribution of flow into parallel channels of vertically oriented heat exchangers or heaters. Experimental verification was based upon a) flow visualisation (injection of a coloured tracer and monitoring the tracer by a camera), b) measurement of temperature profiles, and on c) stimulus response experiments using KCl as a tracer for conductivity methods (2 Pt conductivity probes) and Tc99 as a radioisotope tracer (collimated scintillation detectors).
