Study Of The Flow Field And Scalar Transport Of Indoor Ventilating Space Under The Impact Of Coanda Vortex, Je-Ee Ho, Hong-Tsu Young
Journal of Marine Science and Technology
The vortex in the flow field will isolate the space to further reduce the indoor air exchange and convective efficiency. The Coanda vortex accompanied by the inlet jet usually has the most active effect on the flow field. Both its location and scalar size which are primary determined by the strength of the injected flow and the arrangement of inlet; outlet will deeply affect the air-exchange volume, even reduce the available ventilation space. A 2-D turbulent model with SIMPLE method is set up to simulate the air motion of indoors; it can easily describe the working of Coanda vortex in …
