Cooling using complimentary tapered plenums
TL;DR: In this article, a fluid cooling medium cools a plurality of heat-producing devices arranged in a row along a generalized coordinate direction, with a space between each adjacent pair of devices, each space may have a partition that defines a boundary between a first plenum and a second plenum.

Maximal heat transfer density in vertical morphing channels with natural convection
TL;DR: In this article, the authors show that the entire flow geometry of a vertical diverging or converging channel with laminar natural convection can be optimized for maximal heat transfer rate density.

Natural convection heat transfer in Gambrel roofs
TL;DR: In this paper, the authors investigated buoyancy induced natural convection with a numerical technique in Gambrel roofs and found that winter-like boundary conditions are more effective than summer-day boundary conditions on the flow field and heat transfer in the roof.

Effect of a diffuser on performance enhancement of a cylindrical methanol steam reformer by computational fluid dynamic analysis
TL;DR: In this paper, the effect of the angle and length of the diffuser, and wall temperature have been explored on heat and fluid flow, methanol conversion, hydrogen production, carbon monoxide reduction, as well as estimated net power of fuel cell with the same catalyst volume and entrance condition.

A Numerical Study of Developing Free Convection Between Isothermal Vertical Plates
TL;DR: In this article, the full elliptic forms of the Navier-Stokes and energy equations are solved using novel inlet flow boundary conditions, and the results cast doubt on the validity of previous elliptic solutions.

Heat transfer by free convection between two parallel flat plates
TL;DR: In this paper, an approach that can determine the flow rate with consideration of the pressure drop is proposed, and a comparison is made with Kettleborough's and Aihara's results.
