Progress in the development of a twofluid model of turbulence for nearwall flows, part 1
Abstract
A twofluid turbulence model in which the fluids are defined as fast and slow and the entrainment rate is formulated to be proportional to the volume fraction of the fast fluid is described. The model constants which describe the interfluid mass transfer, friction and diffusion are optimized with reference to a boundary layer. The results based on the set of constants chosen are compared with experimental data. The results show that despite the difference in the definition of the two fluids in the experimental study and the present one, the mean velocities compare favorably.
