Abstract
The generalized dispersion model is used to study the dispersion process in unsteady flow in a tube with wall absorption by modeling the flowing fluid as Casson fluid. According to this model, the entire dispersion process is expressed in terms of three transport coefficients viz., the absorption, convection, and dispersion coefficients. This study brings out the effects of pulsatility, yield stress and wall absorption on these three transport coefficients. It is observed that the convection and the dispersion coefficients are dependent on absorption parameter, yield stress, pressure fluctuating component, and frequency parameter whereas the absorption coefficient depends only on wall absorption parameter. This study can be used to understand dispersion process in blood flows.
