WebSep 28, 2024 · Each aerodynamic force is a function of the following parameters: F = f n ( V ∞, ρ, α, μ, a ∞) Where: V ∞ = free-stream velocity ρ = density of the medium α = angle of attack μ = viscosity of the medium a ∞ = Free stream sonic speed. We can therefore non-dimensionalize the forces and moment in the following way: C L = L q ∞ S. WebSep 5, 2024 · What is drag coefficient in aerodynamics? The drag coefficient is a number which aerodynamicists use to model all of the complex dependencies of drag on shape, inclination, and some flow conditions. The drag coefficient Cd is equal to the drag D divided by the quantity: density r times reference area A times one half of the velocity V squared.
