1D modelling and preliminary analysis of the coupled DYNASTY–eDYNASTY natural circulation loop

open access: yesFrontiers in Energy Research, 2023
In the continuous strive to improve the safety of current-generation and next-generation nuclear power plants, natural circulation can be used to design passive safety systems to remove the decay heat during the shutdown.

Variability of the Atlantic thermohaline circulation described by three-dimensional empirical orthogonal functions [PDF]

open access: yes, 2007
We describe the use of bivariate 3d empirical orthogonal functions (EOFs) in characterising low frequency variability of the Atlantic thermohaline circulation (THC) in the Hadley Centre global climate model, HadCM3. We find that the leading two modes are

Constructal theory of global circulation and climate [PDF]

open access: yes, 2006
The constructal law states that every flow system evolves in time so that it develops the flow architecture that maximizes flow access under the constraints posed to the flow.
