  title = {High Rayleigh Number Convection in Shallow Enclosures with Different End Temperatures},
  abstract = {<p>Buoyancy-driven laminar convection in shallow horizontal enclosures (width/height ⪢1) with adiabatic horizontal walls and isothermal vertical walls of different temperatures has been investigated for very high Rayleigh numbers (<em>Ra</em> ⪢ 10<sup>6</sup>). It is found that this flow regime, which is characterized by boundary layers lining both the vertical and horizontal walls, differs qualitatively from the low-<em>Ra</em> flow regime, in which the horizontal boundary layers are absent. The decreasing influence of <em>Ra</em> on the Nusselt number and the effect of the aspect ratio are analytically shown and then numerically verified. Comparison is made with existing experimental and numerical data, and a new correlation is proposed for the Nusselt number in this flow regime. An explanation is also advanced regarding the current controversy about the power dependence of the Nusselt number on <em>Ra</em> in narrow vertical channels.</p>},
