Exploring natural convection and heat transfer dynamics of Al2O3-H2O nanofluid in a modified tooth-shaped cavity configuration by Bijan Krishna Saha, Jahidul Islam Jihan, Goutam Barai, Nur Jahangir Moon, Goutam Saha, Suvash C. Saha

“…This includes examining the roles of the heated rectangular vertical wall (RVW), the adiabatic circular cylinder, and the magnetic force on the NC of Al2O3H2O nanofluid.Method and validations: This study solves the governing equations and corresponding boundary conditions using Galerkin's weighted residual-based finite element methods. Also, comprehensive comparisons and validations against existing results are conducted to ensure the accuracy of the findings.Parameters: The study involves a range of parameter values, including 0 ≤ nanoparticle volume fraction (φ) ≤ 5 %, 104 ≤ Rayleigh number (Ra) ≤ 106, 0 ≤ Hartmann number (Ha) ≤ 60.Results: The research reveals that insulated wavy top wall and heated RVW significantly shape the flow field and heat transport. …”
