Abstract
Numerical simulations were performed to study the pertinent parameters of natural convection in annular space. The studied geometry consists of two semi-circular cylinders of hot walls confined in cold cavity of circular cross-sectional form. The simulations were done by solving numerically the governing equations via the commercial software ANSYS-CFX. The results showed that this new form of inner cylinders is suitable for insulating applications. The pertinent parameters were selected for this work were: Prandtl number (Pr = 0.71 to 1000) and Rayleigh number (Ra = 103, 104 and 105).
