WebThis research investigates laser-induced convection through a stream function-vorticity formulation. Specifically, this paper considers a solution to the steady Boussinesq Navier–Stokes equations in two dimensions with a slip boundary condition on a finite box. A fixed-point algorithm is introduced in stream function-vorticity variables, followed …

WebStall (fluid dynamics) Airflow separating from an airfoil at a high angle of attack, as occurs at a stall. In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack increases. [1] This occurs when the critical angle of attack of the foil is exceeded. The critical angle of attack is typically about ...
