Natural convection in liquids [PDF]
Lorenz (1881) gave a solution to the problem of natural convection set up near a heated vertical plate, in which he assumed that the surfaces of equal fluid velocity and equal fluid temperature are parallel to the plate. Experiments show, however, that this is not the case.

Biomass gasification for syngas and biochar co-production: Energy application and economic evaluation [PDF]
Syngas and biochar are two main products from biomass gasification. To facilitate the optimization of the energy efficiency and economic viability of gasification systems, a comprehensive fixed-bed gasification model has been developed to predict the ...

Destruction of the family of steady states in the planar problem of Darcy convection [PDF]
The natural convection of incompressible fluid in a porous medium causes for some boundary conditions a strong non-uniqueness in the form of a continuous family of steady states.

A “poor man’s” approach to topology optimization of natural convection problems [PDF]
Topology optimization of natural convection problems is computationally expensive, due to the large number of degrees of freedom (DOFs) in the model and its two-way coupled nature.

Natural convection could arise even at ultra-low redox concentration solutions (1–10 mM). Models such as convection–diffusion layer model and spontaneous convection model have been established to describe this phenomenon.

Natural convection reactor [PDF]
A previous report described the conceptual design of a plutonium producing reactor that may be characterized as follows: Power output (2000 MW); cooling - (natural convection of light water through the reactor, up through a draft tube to an evaporative cooling pond, then back to the reactor, and fuel (400 to 500 tons of uranium enriched to 1.2% U-235).
