Abstract:
The exploration of rotational dynamics within fluid motion holds profound importance across
diverse fields such as industrial chemical processes, advancements in food processing
technologies, the optimization of turbomachinery, efficient cooling techniques for computer
storage drives and various other applications. This study assesses entropy creation in MHD
viscoelastic flow using the intriguing Walters-B and Jeffery model over a linearly deforming plate
within a rotating frame of reference. The inclusion of Coriolis and centrifugal forces due to the
rotating frame introduces additional terms in the momentum balance equation. Furthermore, the
energy equation, which includes terms for viscous dissipation and Joule heating, is examined. The
representative non-linear problem is analyzed through optimal homotopy analysis method
(OHAM) available within the “MATHEMATICA” package “BVPh 2.0”. This routine is
implemented to retrieve the optimal auxiliary parameters and corresponding averaged squared
residuals for varying homotopy approximations. The drag on the plate and the surface cooling rate
are assessed under the rotating fluid assumption, with varying material parameter of the Walters
B and Jeffery model. Additionally, the impact of heat dissipation on the overall heat transport
phenomenon is thoroughly examined.
