MODELLING OF MULTI-PHASE FLUID FLOW WITH VOLUME FRACTION PAST A PERMEABLE STRETCHING VERTICAL CYLINDER AND ITS NUMERICAL STUDY

Abstract

A steady two-dimensional mixed convective multi-phase fluid (base fluid containing dust particles) flow past a vertical stretching cylinder in presence of volume fraction has been investigated. The surface of cylinder is embedded by porous medium in presence of non-uniform source/sink. Governing partial differential equations of the problem for both fluid and dust phases are converted into ordinary differential equations using similarity transformations. MATLAB built-in bvp4c solver technique is used to solve the resulting non-linear differential equations. The results are presented in graphical forms for various values of flow parameters.
