Boundary condition for fluid flow: Curved or rough surfaces
WebFeb 3, 2024 · Fractures typically contain multiscale surface features and can impact the fluid flow within. Direct numerical simulations across a wide range of Reynolds number have been carried out on surfaces with roughness details of different length scales. The overestimation in permeability due to surface approximation is quantified, leading to a … WebMay 1, 2024 · For a turbulent boundary layer over a smooth surface, a thin layer of laminar flow known as the viscous sublayer forms along the entire length of the surface, as shown in Fig. 1 (a). For the same flow over a rough surface Fig. 1 (b), the roughness increases flow instability close to the wall which can lead to increased localised turbulence … suzuki sierra lj80
