Experimental characterization of the PT asymmetry with balanced inflow and outflow at different Reynolds numbers
Abstract
This research focused on characterizing the PT asymmetry with balanced inflow and outflow conditions at different Reynolds number using experimental method. The characterization process utilized PIV data to explore the relationship between PT asymmetry and Reynolds number in two different experiments. In the first experiment, balanced inflow and outflow are used to generate the flow field in a cuboid test section with different Reynolds number, the inflow and outflow are located at the central of left side and right side of the test section. In the second experiment, a main flow is introduced to the first experiment by adding another inflow and outflow which locate at a symmetric position on the bottom side of the test section. The flow field is generated by the two inflows and outflows with different Reynolds number. The results show that there is a linear relationship between PT asymmetry and Reynolds number when Reynolds number is less than 200 for a balanced inflow/outflow situation. They also show that there is a decreasing trend of PT asymmetry when Reynolds number increases for balanced inflow/outflow combined with main flow.
