Opis:: This paper presents the application of Chebyshev spectral collocation method to flow analysis of a micropolar fluid conveyed through porous channel driven by suction or injection with high mass transfer. Effects of flow and rotation parameters such as Reynolds number and micro rotation parameters on the flow characteristics of the micropolar fluid are investigated using the developed approximate analytical solutions through the method. Comparing the results of the numerical solutions obtained in this study with the other results of the other methods in literature, very good agreements are established. The results obtained from this work can be used to further the study of the behavior of micropolar fluids in applications such as lubricants, blood flow porous media, micro channels and flow in capillaries.

Opis:: In this paper, a two-step implicit hybrid block multistep method is proposed for the approximate solution of higher order ordinary differential equations with a specification of fourth order. The study provides the use of both collocation and interpolation techniques to obtain the schemes. Direct form of power series is used as basis function for approximation solution. An order eight symmetric and zero-stable method is obtained. To implement our method, predictors of the same order of accuracy as the main method were developed using Taylor’s series algorithm. This implementation strategy is found to be efficient and more accurate as the result has shown in the numerical experiments. The result obtained confirmed the superiority of our method over existing methods.
