Abstract
We present a refinement of a model due to Mondal and Mazumder [7] for
dispersion of fine particles in an oscillatory turbulent flow. The model is based
on the time-dependent advection-diffusion equation posed on a semi-infinite
strip, and whose solution represents the concentration of particles over time
and down-stream distances.
The problem is solved by first mapping to a finite domain and then using
a monotone finite difference method on a tensor product, piecewise uniform
mesh. The numerical results obtained for the related steady-state problem,
and are compared with experimental data.
