Webb28 sep. 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. WebbA general, CFD-based frequency response method for obtaining the dynamic coefficients of hydrodynamic bearings is presented. The method is grounded in experimental parameter identification methods and is verified for an extremely long, slider bearing geometry as well as short and long journal bearing geometries. The influence of temporal inertia on the …
