. Drag force. The surrounding fluid exerts pressure forces and viscous forces on an object. .. The components of the resultant force acting on the object immersed in the fluid are the drag force and the lift force. .
In a flow, the boundary layer represents a (relatively) thin layer of fluid that is nearest the solid boundary. 87-351 Fluid Mechanics. [ physical interpretation: what are we doing today? ]. The behaviour of the boundary layer is very different from that of the fluid above it.
