Boundary layers are often studied with no pressure gradient or with an imposed pressure gradient. Either of these assumptions can lead to difficulty in obtaining solutions. A major advance in fluid dynamics last century (1969) was the development of a triple deck formulation for boundary layers where the pressure is not specified but emerges through an interaction between boundary layer and the inviscid outer flow. This has given rise to new computational problems and computations have in turn fed ideas back into theoretical developments. In this survey talk based on my new book, I will look at three problems: flow past a plate, flow separation and flow in channels and discuss the interaction between theory and computation in advancing boundary layer theory.
