Flow and Heat Transmission Analysis of Rayleigh-Bénard Convection Driven by Newtonian Fluid with Colloidal Suspension

An investigation of Rayleigh-Bénard convection between two parallel plates has been conducted. Single-phase nanoliquid flow and heat transfer system has been considered to model the dynamics. In this examination, Maxwell-Bruggeman and Krieger-Dougherty model were adopted to describe the impact of aggregation kinematics on thermal characteristics. Stress-free and isothermal boundary condition are assumed. The Ginzburg-Landau model for the considered flow geometry is obtained using a three-mode model. It is observed that the considered model with nanoparticle aggregation is a realistic one. Cell size and trajectories of the flow dynamics are found to be uninfluenced by aggregation while Nusselt number is significantly reduced due to it.
