Numerical Investigation of Thermal Performance for Pulsating Flow in a Microchannel Heat Sink Filled with MXene Fluid

An A microchannel heat sink, which includes a heat exchange cavity, are a variation of fin and tube heat exchangers. Fluid, in the form of a coolant, flows through tubes or enclosed channels, the hydraulic diameter of the channels is less than 1 mm. The fluid used in the simulation is MXene based nanofluids, MXenes are two dimensional inorganic compounds which combine the metallic conductivity of transition metal carbides with a hydrophilic nature because of their hydroxyl- or oxygen-terminated surfaces. They tend to have good thermal conductivity and the aim of the study is to prove the difference in heat transfer between MXene fluid and water. The nanofluids are passed through the Micro Channel Heat Sink using a pulsating flow driven by square wave are to improve the thermal performance. ANSYS is used to numerically simulate the environment of the microchannel and to predict the outcome of the study. A mesh sensitivity study has been conducted to determine the mesh which is the most accurate to conduct the further study. The results obtained were mainly discussed using few fundamental concepts like the Velocity, Pressure and Temperature Contour together with the Nusselt Number Analysis to determine the trends between fluid with various pulsating frequency.
