Natural convection in horizontal annulus with heated blocks
- Univ. of Akron, OH (United States). Dept. of Mechanical Engineering
Conjugate natural convection in a horizontal circular annulus with equally spaced blocks has been studied numerically. The inner surface of the annulus is insulated and is covered by a thin layer that generates heat, whereas the outer surface is isothermal. Cases of both with and without heat generation in the blocks, which is half the strength of that on the inner wall, are examined. It has been shown in this two-dimensional study that, with the existence of the blocks, the physical prospects of the convective flow and heat transfer within the annulus could be totally different from those of the simple annulus. The flow and temperature fields are found resulting from the coupling of the global recirculation and the local eddies.
