WebL i f t = q S C L. The dynamic pressure q = 1 2 ρ v 2. S is the planform area. C L is the lift coefficient. ρ is the air density. v is the air velocity. What you really want to test for is the lift coefficient - you can use that to calculate the lift force during flight for a given dynamic pressure and planform area. WebDynamic similarity, the dimensionless science Dimensional analysis, a framework for drawing physical parallels between systems of disparate scale, affords key insights into …
WebMay 5, 2024 · To ensure the geometric and dynamic similarity, the testing parameters for the five wind turbine sizes were determined for the desired range of wind velocities and TSRs. The experiment will be carried out in one wind tunnel, therefore special attention must be paid to satisfy the conditions of aerodynamic similarity.
Wind Tunnel Testing. The concept of dynamic flow similarity is a fundamental issue in wind tunnel testing of sub-scale models. Suppose a sub-scale model of an aircraft is to be tested in a wind tunnel. In that case, the basic idea is to simulate the conditions of free flight, i.e., to simulate the actual flight … See more The principle of dynamic similarityis connected to the preceding concepts used in dimensional analysis.
