THE DEVELOPMENT OF AEROFOILS FOR WINGS It would appear that any plate-like object set at an angle to a wind (angle of incidence, or attack) will experience a lift force irrespective of the presence or absence of a thin boundary layer. However, theoretical analysis of ideal inviscid flow around a very thin flat plate shows that the direction and speed of the flow (that is, the flow velocity vector) downstream of the plate are the same as that of the oncoming flow. Momentum is a vector quantity equal to the product of the mass and the velocity vector of the mass.

3(a). This steady form of boundary layer is termed 'laminar'. Small random disturbances of this smooth flow pattern, such as those generated by roughness of a body's surface or turbulence in incoming flow, are rapidly damped out by viscosity which acts so as to suppress random fluid motion: the boundary layer is stable. As the product of airspeed and distance from the 'nose' increases, the control of such disturbances by viscosity becomes weaker. Eventually the whole flow becomes unstable and superimposed on the streamwise flow there exist random fluctuations of flow velocity in the form of regions of circulating flow, known as 'eddies', that grow, mix and die as new ones arise.

It is clearly impossible to construct a 'microscopic' model of a fluid which explicitly and precisely represents the motions of each of its component molecules - there are simply far too many. However, it is possible to construct a 'macroscopic' model which is based on the assumption that a fluid is continuous (voidless). For the purpose of representing its kinematic (motional) state a fluid is conceptually divided into minute elements of which the properties and states at any one time represent the average properties and states of the millions of molecules within the boundaries of the element at that instant of time: these elements are called 'particJes'.
