disso22 New Member Join Date: Jun 2022 Posts: 1 Rep Power: 0	I am simulating the flow over a singular obstacle in flume flow, maintaining all set parameters but moving the distance between the inlet and the obstacle leads to a big decrease in drag coefficient, any ideas why? For a singular square it should be around 2.1, which i get close to at 1 Diameter upstream, however at a reasonable distance of 5 Diameter it is below 1 (should remain similar to the first value). Any help appreciated Last edited by disso22; June 29, 2022 at 06:19.
