The lift coefficient for incompressible flow, often denoted as cl is a dimensionless parameter used in aerodynamics to quantify the lift generated by an airfoil or aerodynamic surface under conditions where the flow can be approximated as incompressible. In incompressible flow, the local flow velocity is much less than the speed of sound, and density variations due to changes in velocity are relation.Â
