Abstract
The thesis describes the modifications made to a transport model which characterises turbulence by two properties: K the specific kinetic energy of the fluctuating motion; and W, the time-mean souare of the vorticity fluctuations.Partial differential eauations expressing the conservation of these Quantities are solved numerically, along with those for the momentum and enthalpy.Emphasis is placed on the correct modelling of the near-wall region to account for the effects of the special features of the flow situations considered.Unlike the practice with
