The authors of the present paper sought to conduct a numerical study on convection heat transfer, along with radiation and entropy generation (EGE) nanofluids (NFs) in two three-dimensional square enclosure, by using FVM. enclosure contained high-temperature blade form vertical elliptical quadrant lower corner enclosure. right edge was kept at low temperature, while other edges were insulated. ...

The aim of the present numerical study is to analyze the conjugate natural convection heat transfer in a differentially heated square enclosure containing a conductive polygon object. The left wall is heated and the right wall is cooled, while the horizontal walls are kept adiabatic. The COMSOL Multiphysics software is applied to solve the dimensionless governing equations. The governing parame...

Conjugate natural convection-conduction heat transfer in a square enclosure with a finite wall thickness is studied numerically in the present paper. The governing parameters considered are the Rayleigh number (5 × 10(3) ≤ Ra ≤ 10(6)), the wall-to-fluid thermal conductivity ratio (0.5 ≤ Kr ≤ 10), and the ratio of wall thickness to its height (0.2 ≤ D ≤ 0.4). The staggered grid arrangement toget...
