Rotating oscillations of solar cooker with a permeable bar plate in a couple stress of fluid dynamics

Abstract

In this paper an attempt is made to study the flow of heat generated by rotary oscillations of a permeable bar plate in an immeasurable area of an incompressible couple stress fluid. The solar cooker heat flow generated is explained in Stokesian hypothesis for velocity field in the form of modified Bessel functions. The couple acting on the bar plate temperature due to external heat flow as well as internal heat flow is considered. The influence of solar cooker with in both relative couple stress parameter has been achieved and to different couple stress parameters are drawn to analyze the heat flow in bar plate area. The solar cooker heat flow for the couple stress to the particles move to near the area is thrown away with high velocity of the bar plate area.
