โœฆ Synopsis

A thermodynamic approach to the boundary layer flow system is used to investigate the control rule underlying the flow field. Application of Pontryagin's Maximum Principle from control theory shows minimum rate of entropy production to be the control rule for the flow field, in common with other dissipative processes. This result is used to investigate possible organised motion in the turbulent boundary layer and the generation of longitudinal vortices which is known to be an intrinsic characteristic of turbulence.

For the irrotational flow of an incompressible non-Newtonian fluid the viscous terms in the equation of motion are not identically zero (unless the fluid moves as a solid body). This suggests that (except for flow past a flat plate with zero angle of incidence) a non-Newtonian boundary-layer solutio

An idealized geometry is adopted in order to calculate the equilibrium configuration of a constant volume of liquid initially partially wetting a grain boundary intersecting a free surface. To minimize the excess interfacial free energy, competition exists between the liquid as it dewets creating ad
