dc.description.abstractThe present anulysis brings out the interaction of curcature and a weak wall absorption parameter on the dispersion process using Taylor analysis. A perturbation series solution has been obtained to find the values of the effecti1.e dispersion coefficient. The constraints imposed by the perturbation techniques hate been removed using a numerical scheme based on spectral method. Results ore found to be applicable for a time at which the Taylor dispersion model holds. It has been obsened that in the interphase transport of reactice contaminants the effectit’e dispersion coefficient is significantly diflerent from that of Taylor due to the wall absorption parameter. The results corresponding to the straight tube are Lqerified with the published results, and those obtained from the perturbation and spectral techniques are found to be comparable. The restriction of the present analysis is confined to the effect of weak wall absorption under laminar flow conditions. This restriction needs to be relaxed. For moderute or large r,alues of the absorption parameter a generulized dispersion model has to be resorted to.en
