Abstract

One type of non-Newtonian fluids is viscoelastic fluid. The characteristics of this fluid are viscous and elastic. Many researches have been done on non-Newtonian fluid, one of which the magneto hydrodynamics viscoelastic fluid, especially for the application in engineering field. This study will research about the problem of magneto hydrodynamics viscoelastic fluid passing through the flat plate. The governing equation of the flow is solved using the boundary layer theory. The boundary layer equations are then transformed into a non-dimensional form using the stream function equation. The numerical results are analyzed the effect of viscoelastic parameter (K), magnetic parameter (M), and Prandtl number (Pr) to the velocity profile(f^\\ ) and temperature profile (#952). Based on numerical simulations that have been conducted, it can be concluded that the values of velocity (f^\\ ) decrease when the magnetic parameter, viscoelastic parameter, and Prandtl number increase. The values of temperature profile increase (#952) when the viscoelastic parameter and magnetic parameter increase, but it will be decrease when Prandlt number increase.
