Tīmeklis2024. gada 1. marts · 1.3. Separated-flow transition. When a laminar boundary layer separates or when laminar flow separates at a blunt/sharp/rounded leading edge of a flat plate, transition may occur in the separated free shear layer of the flows. This is called separated-flow transition (or called separated boundary layer transition). Tīmeklis2024. gada 2. marts · Airfoils operating at low Reynolds number have a proclivity to induce a laminar separation bubble (LSB) on their upper surface. We investigate the effects of angle of attack on the characteristics of the LSB and the flow field around a NACA0012 airfoil. Large-eddy simulations show that there are three distinct angle-of … Tīmeklis2024. gada 18. marts · The laminar bands of color to the west bleeding out under the hammered clouds.
