Openfoam skin friction coefficient
Web12 de ago. de 2024 · Cf = Skin Friction Coefficient. Firstly we need to calculate Skin Friction Coefficient from the formula given. Cf = 0.074 / (Rex)^1/5. For this Rex is the Reynolds Number based on the whole length of the plate. From before Rex = 10^7 for the whole plate. Now we can calculate Cf. Cf = 0.074 / (10,0000,000)^1/5. Cf = 0.074 / … WebThe friction force is the force exerted by a surface when an object moves across it - or makes an effort to move across it.. The frictional force can be expressed as. F f = μ N (1). where. F f = frictional force (N, lb). μ = static …
