Abstract : Contents: A study of sudden expansion pipe flow using an algebraic-stress model of turbulence; Comment on 'The flowfield in a suddenly enlarged combustion chamber'; Turbulent flow prediction in a sudden axisymmetric expansion; Heat transfer to turbulent swirling flow through a sudden axisymmetric expansion; Measurements in turbulent swirling flow through an abrupt axisymmetric expansion. The first three papers describe numerical predictions of the flowfield; The next describes experimental measurements of local convective heat transfer on the tube walls downstream of expansion; and the last describes detailed mean and fluctuating flowfield measurements both upstream and downstream of the expansion including precessing vortex core phenomena.
