Experimental Investigation of Bubbly Flow Mixing inside a Washer Basin with an Immersed Coiled Heater

Abstract:

The flow structure inside a water basin that, serves as a water tank of a modeled washer system with an immersed coiled heater and air supply nozzle is investigated experimentally. To obtain the flow velocity field, particle image velocimetry is employed, and different view-point sections are analyzed. A large-scale vertical flow structure, which is attributed to the strong air jet flow enhancement, causes the development of a 3D mixing layer in the entire flow regime. Although a coiled heater can provide buoyancy to the working fluid, the bubbly flow structure significantly dominates this stage by supplying air from the bottom nozzles.
