Beltrami flow of an Unsteady Dusty fluid in an Open Rectangular Channel
C.S.Vishalakshi,B.J.Gireesha,C.S.Bagewadi 장전수학회 2011 Proceedings of the Jangjeon mathematical society Vol.14 No.1
An analytical study is made on Beltrami flow of an unsteady dusty fluid in an open rectangular channel. The flow is due to the influence of movement of the plates. Flow analysis is carried out in Frenet frame field system and exact solutions of the problem are obtained by solving the partial differential equations using Laplace and Finite Fourier sine transform methods. Further graphs drawn for different values of Reynolds number and on basis of these the conclusions are given. Finally, the expressions for skin-friction at the boundaries are obtained.
Pulsatile flow of unsteady dusty fluid through porous media in anholonomic co-ordinate system
B.J.Gireesha,C. S. Bagewadi,K. R. Madhura 장전수학회 2007 Proceedings of the Jangjeon mathematical society Vol.10 No.2
The present analysis deals with the study on unsteady flow of an incompressible viscous dusty fluid with uniform distribution of dust particles in porous media. The flow is due to the influence of pulsatile pressure gradient and the motion of plates. The flow analysis is carried out using differential geometry techniques and the problem is solved by the application of Laplace Transform technique. The effects porosity parameter on the components of velocity of both fluid and dust particles are studied with the help of graphs. Further the shear stress is obtained at the boundaries.
