Abstract
En 中文
This research paper focuses on the computational study of Nadeem Trigonometric non-Newtonian (NTNN) fluid model with convection flow of SWCNT/H2O nanofluid to study heat transfer aspects in a porous Trash bin-shaped cavity enclosing a Tuning fork-shaped fin. Investigators have commonly recognized the placement of fins inside the cavities due to its applications such as heat-producing units in heat exchangers, gas turbines, conventional furnaces, superconductor heaters and economizers. Fins have promising applications in power engineering, automobile industry, microelectronics, chemical processing and aerospace engineering. The advanced technological processes involve the utilization of these fins inside the geometrical cavities to study the heat transfer mechanism. Current research is organized to study heat transfer aspects and convective movement of SWCNT-H2O nanofluid in the porous Trash bin-shaped cavity. A Tuning fork-shaped fin is fitted at the bottom wall of the cavity to enhance the heat transfer process. The impact of Magnetohydrodynamics (MHD) is invoked. The finite element method is implemented to solve governing nonlinear PDEs. Numerical simulations are performed via COMSOL to investigate the impacts of the Rayleigh number (104 <= Ra <= 106), volume fraction of SWCNT (0.01 <=phi A <= 0.05), Darcy parameter (10-5 <= Da <= 10-1) and Hartmann number(0 <= Ha <= 80) on flow patterns, thermal distribution and heat transfer rate. Average Nusselt numbers are computed. Current communication reveals that the heat transport rate elevates by augmenting the Rayleigh number, volume fraction of SWCNT, and Darcy parameter. Nusselt numbers are reduced by non-Newtonian fluid parameter N and Hartmann number.
