Abstract
The performance of incompressible, laminar, boundary- layer flows over a semi-infinite horizontal stretchable plate is considered. The dusty fluid flow problems are modelled and solved in agreement with two-way coupling model. The particle phase momentum equation in the vertical direction is considered where as that for fluid phase is neglected. Here the electrification term added in not from the supply from outside rather it is the generation due to collision of particles So the effects of particle loading and electrification on velocity profile have been studied. From the result analysis it is concluded that electrification and particle density have significant effect on particle phase velocity, whereas carrier fluid phase has negligible effect. The particle phase velocity increases with increasing of electrification parameter and decreases with increase of loading ratio.
Highlights
The study of velocity allocation in the boundary layer flow over a surface is crucial for it’s application in diversified field
Crane [1] has modelled the flow over a linear stretching sheet and solved and got in exponential form
The problem of two-phase flow is solved in the way of two-fluid approach
Summary
The study of velocity allocation in the boundary layer flow over a surface is crucial for it’s application in diversified field. Sharidan[10] offered similarity solutions for velocity allotment in unsteady flow that was generated due to suddenly enlargement of stretchable sheet. Crane [1] has modelled the flow over a linear stretching sheet and solved and got in exponential form. Gireesha et al[7,8,9] have modelled and discussed about the impact two phase flow over an unsteady stretchable sheet. The analysis of dusty fluid flows is very much essential to model and finding solution of the problems, like environmental pollution, centrifugal separation of particles, blood rheology, etc. The role of electricity generated and loading ratio on velocity profile the boundary layer have been studied
