Abstract

In this work, two-dimensional numerical simulations are carried out to study the mixed convection heat transfer past two equal-sized rotating isothermal circular cylinders in tandem arrangement confined inside a vertical channel. The governing equations are solved using the finite element method (Freefem++) with based optimization, and the effects of rotation speed have been assessed for fixed spacing and blockage ratios for different values of rotation rates. The numerical scheme is first validated against standard cases of symmetrically confined isothermal circular cylinders in plane channels. Stiff time convergence tests are also examined. The numerical performance is compared against a parallelized (OpenMP) finite volume based numerical method developed in Fortran 90 to evaluate the performance of the based optimization. The results demonstrate that the optimized model developed in this study can be used as an effective tool to save computational resources.
