STABILITY PERFORMANCE OF A NON-NEWTONIAN LIQUID OVER AN OSCILLATORY SUBSTRATE
Abstract - This paper investigates the time-dependent flow of a viscoelastic contaminated thin film in the existence of porous media and heat transfer. The fluid is moved on a horizontal plate, in which the liquid and the plane are both at relaxation initially. Suddenly, the substrate is vibrated into the flow at its own level with an oscillatory speed. The non-dimensional equations and conditions for the considered model have been done. The inversion of the Laplace transform is used to produce numerical outputs. Numerical perceptions show that each of the Péclet and capillary numbers help the growth of the temperature. In the case of vanishing Reynolds number, the capillary number works to decrease the rise of waves, while increasing the elasticity number plays an opposite impact.
