An incompressible boundary layer is subjected to a pressure rise Ap between stations 1 and 2, which are very close together. The shape of the bound- ary layer at station 1 is satisfactorily described by u/U = (1/8), in which U and 8 are known quantities. Neglecting the action of viscous forces be- tween stations and 2, determine how much boundary layer fluid would need to be removed by suction to prevent separation at station 2. How would viscosity tend to affect this result? B U PROBLEM 3 Suction 47 An incompressible boundary layer is subjected to a pressure rise Ap between stations 1 and 2, which are very close together.
