Flow of a Second‐Order Fluid past a Symmetrical Cylinder

Abstract: The velocity profile within the boundary layer region for the flow of a second‐order fluid past a symmetrical cylinder has been determined for various values of a nondimensional parameter formed out of the velocity and material constants. As an example, the flow past a circular cylinder has been discussed in detail, and the separation point has been calculated for different values of the above mentioned parameter. It is found that the increase in second‐order effect shifts the point of separation towards the forward stagnation point.

Unsteady flow of a second-order fluid near a stagnation point

Abstract: Two-dimensional flow of a second-order fluid near a stagnation point occurring on a flat plate which is performing harmonic oscillations in its own plane is considered. The equations have been integrated by the Karman-Pohlhausen method for small values of ω, the frequency of the oscillation of the plate, and the W.B.K. method is applied to solve the equations for high values of ω. The velocity profile within the boundary-layer region and the shearing stress on the plate have been obtained in both the cases. The oscillation of the shearing stress has a phase lead over the oscillation of the plate. This phase lead decreases with increase of the second-order effect for small values of ω.

Free convection flow of a second order fluid past a hot vertical plate

Abstract: Laminar free convection flow of a second order fluid past a hot vertical plate with varying wall temperature has been studied in this paper. Exact solutions for the velocity and temperature fields have been obtained. The effects of elastic coefficient on the velocity and temperature fields, rate of heat transfer and the skin-friction have been studied.
