Transversally flowing fluid in a laminary boundary layer on a permeable surface

Behavior of a transversally flowing fluid in a boundary layer on a plate and a wedge is studied using the Faulkner–Scan equation in the presence and absence of suction and blowing on the body surface. Numerical methods are used to show that, under certain conditions in the boundary layer, one may observe the formation of attraction and repulsion lines (the transverse velocity along these lines is zero) and maximum transverse velocity lines. Different transverse flow regimes in the boundary layer depending on the key parameters of the problem are considered.
