These two volumes are concerned with current technologically important issues of transition, turbulence and combustion. Topics covered in transition include linear and nonlinear stability, direct and large-eddy simulation and phenomenological modelling of the transition zone. In turbulence, interest was focused on second-order closures and the formulation of near-wall corrections to existing high Reynolds number models, and closure model development based on turbulent flow structures and RNG theory. Topics covered in combustion include counterflow diffusion flames, development of novel mixing enhancement techniques for non-premixed combustion, and methods of modelling the interaction between turbulence and chemical kinetics. This collection of papers from leading researchers represents as yet unpublished state-of-the-art research, resulting in a very valuable tool for scientists and students working in areas of turbulence, transition and combustion.
