Abstract: In this study, an analysis has been performed for heat and mass transfer with radiation effect of a steady laminar boundary-layer flow of a micropolar flow past a nonlinearly stretching sheet. Parameters n, K, k0, Pr, Ec, and Sc represent the dominance of the nonlinearly effect, material effect, radiation effect, heat and mass transfer effects which have presented in governing equations, respectively. The similar transformation, the finite-difference method and Runge–Kutta method have been used to analyze the present problem. The numerical solutions of the flow velocity distributions, temperature profiles, the wall unknown values of θ′(0) and ϕ′(0) for calculating the heat and mass transfer of the similar boundary-layer flow are carried out as functions of n, Ec, k0, Pr, Sc. The value of n, k0, Pr and Sc parameters are important factors in this study. It will produce greater heat transfer efficiency with a larger value of those parameters, but the viscous dissipation parameter Ec and material parameter K may reduce the heat transfer efficiency. On the other hand, for mass transfer, the value of Sc parameter is important factor in this study. It will produce greater heat transfer efficiency with a larger value of Sc.

TL;DR: In this paper, a model that predicts the combined effects of axial dispersion and wall channeling has been developed to explain the results obtained with undiluted beds in which all particles are active in the process of mass transfer.

TL;DR: In this article, a set of non-charged similar molecules is chosen as solutes to minimize other interactions apart of those related to size. André et al. used the hydrodynamic model to characterize the behavior of the membrane to uncharged solutes, assuming that membrane pores are straight and cylindrical.

TL;DR: In this paper, a Nernst-Planck based model combining internal and external diffusion resistances has been used to describe the ion exchange process, where the convective mass transfer coefficient and the self-diffusivities of the counter ions are the unique parameters.
