The present results were compared favorably with three correlations [37, 85, 22] as shown in Fig. 3. Also Fig. 5 × 103 < RaH < 105 . 5 × 103 , larger than 1708 for the infinite layer via linear stability theory owing to the finite aspect ratio of the solution domain [23]. This slight delay is due to the enhancement of the effective viscosity by the cylindrical wall [72] and the delay of onset Rayleigh number is also observed by enhanced effective thermal conductivity and enhanced effective viscosity by [43].
