With development of higher electronic devices, there is a need for better thermal management. The heat output of these devices can potentially exceed the heat transfer capabilities of current heat pipe designs. Oscillating heat pipes (OHPS) have high heat spreading performance and are capable of removing higher heat fluxes. OHP is superior compared to traditional heat pipes and can be used to solve the future cooling problems. This study presents the thermal performance of Flat plate oscillating heat pipe (OHP) using different working fluids with mini channels. The FP-OHP were fabricated with the channels of square cross section which had hydraulic diameters of 2 mm in mini channels. The performance of the FP-OHP will be measured and analysed by keeping 50% filling ratio, vertical position and varying input power and with different working fluids.

“…Increase in viscosity results in higher pressure drop and reduces the second law efficiency. 1 In addition to the use of working fluids and geometries, entropy generation in any thermal system depends on the type of cooling methods. Conventional cooling method (single-phase heat transfer) which involves air and liquid fails to reduce the entropy generation.…”

“…Bejan [35] has introduced a general methodology for entropy generation analysis for forced convective heat transfer over a plate and circular cylinder. This entropy generation minimization approach has been applied by many authors [36][37][38][39][40][41] in a wide spectrum of thermo uid systems.…”

A theoretical study of unsteady magnetohydrodynamic boundary layer stagnation point flow, heat and mass transfer of a second grade electrically-conducting nanofluid from a horizontal stretching sheet with thermal slip and second order slip velocity effects is presented. The Buongiorno formulation is employed for nanofluids and in addition the no-flux nanoparticle boundary condition is also considered. The appropriate similarity transformations are applied to convert the governing equations into the system of nonlinear partial differential equations, which is solved by using homotopy analysis method. Entropy generation and Bejan number have also been evaluated for the effects of magnetic parameter, Reynolds number and slip parameter in non-Newtonian (second-grade) time-dependent flow. The computations show that skin friction coefficient and entropy generation number increase with an increment in magnetic parameter whereas Bejan number decreases with it. Local Nusselt number decreases with an increase in the value of Eckert number (viscous dissipation) and thermal slip whereas the converse behaviour is captured for velocity parameter. The work is relevant to magnetohydrodynamic nanomaterials processing.
