Study of the Heat Transfer and Simulation Through a Nanotube for Distribution Function D2Q9 Using the Lattice Boltzmann Method

Nanotubes-based nanofluidsoffer unique thermal and thermoelectric capabilities, opening up new possibilities in electronic device thermal control. In the digital era, life without electronic gadgetsisimpossible to imagine. Mostly people prefer small compact size devices which leads to sudden collapse due toproblems in the transfer of heat. Nanofluids have emerged as one of the best options as Nano coolants. For thisapplication of nanofluid in electronic systems, we first need to analyze its properties. For this, we use the Lattice Boltzmann Method (LBM). Lattice Boltzmann method is one of the most powerful tools that hasmany applications in solving and analyzing complex fluid flow problems involving nanotube-based nanofluids because it is simple to program and mainly due to its computational locality. In this study, the transfer of heat and the hydrodynamicdomain are numerically studied and analyzed by using LBM of second order. The study is done by taking different Reynold numbers i.e., Re = 20,60, and 80, and with different boundary conditions including force buoyancy, the effect of taking different Reynold numbersis analyzed. We try to simulate the flow of fluid through the cylindrical channel. Results are analyzed using the Python software and we can see a fluctuation in the velocity and the vorticity in all the cases while taking nanofluids.
