Internal heating profiles for which downward conduction is impossible

Ali Arslan, Giovanni Fantuzzi, John Craske +1

We consider an internally heated fluid between parallel plates with fixed thermal fluxes. For a large class of heat sources that vary in the direction of gravity, we prove that $\l…

Mixing and ventilation in a living laboratory due to fast and slow response modes

Costanza Rodda, John Craske, Graham Hughes

We present and analyse observational data from a highly instrumented classroom computer laboratory and develop a multizone model to describe its mechanical ventilation and mixing r…

Stochastic models of ventilation driven by opposing wind and buoyancy

Veronica Andrian, John Craske

Stochastic versions of a classical model for natural ventilation are proposed and investigated to demonstrate the effect of random fluctuations on stability and predictability. In…

Unified description of turbulent entrainment

Maarten van Reeuwijk, J. Christos Vassilicos, John Craske

We present a mathematical description of turbulent entrainment that is applicable to free shear problems that evolve in space, time or both. Defining the global entrainment velocit…
