Fast Experimental Estimation of Drag Coefficients of Arbitrary Structures

We present a setup for simple and fast experimental estimation of drag coefficients. Our system can accurately determine the parameters of fluid-object interaction for complicated geometry and boundary conditions. Obtained results are compared with theoretical and numerical solutions. Good agreement with those references is achieved in both cases. An advantage of our method is the prompt and easy parameter retrieval that still maintains appropriate accuracy. Comparable detailed numerical estimations run on the order of hours or days.
