The primary objective of this study is to investigate the thermal and fluidic behavior of a Williamson hybrid nanofluid, which is an integration of nanoparticles with Williamson fluid.Williamson hybrid nanofluid is composed of a non-Newtonian fluid (Ethylene glycol) with nanoparticles (Molybdenum Cot Mobile disulfide, Zirconium dioxide and Graphene oxide).The impact of various combinations of nanoparticles with the base fluid has been examined and it has been determined that Molybdenum disulfide + Graphene oxide / Ethylene glycol is an effective combination of efficient and enhanced heat transfer.A microcantilever sensor was positioned amidst the plates to monitor the rheological behavior and flow characteristics.

This study has potential applications in microscale heat transfer devices and also in an advanced thermal management system.The governing equations incorporating the Williamson fluid model as well as the effects concentration of nanoparticles, magnetohydrodynamics (MHD), permeability, thermal radiation and viscous dissipation are derived.Further, a comprehensive numerical analysis of the squeezed flow of Williamson hybrid nanofluid over a microcantilever sensor has been performed and solved using MATLAB solver.The graphical and tabulated illustrations are used to depict the influence of different control factors on flow phenomena.

Elevation in the Weissenberg number and the permeable velocity parameter shoots up the temperature profile.As the values of permeable velocity parameter and squeezed flow index rise, the velocity profile decelerates.On the other hand, the velocity Joint profile uplifts when there is an escalation in the magnetic number.The magnitude of the Nusselt number gets amplified for the increasing values of squeezed flow index.

Moreover, the importance of fluid friction and heat transfer is analysed elaborately.
