Ventilation, stratification and flow instability driven by vertically distributed buoyancy sources
… instability, distinguishing these `annular wall plumes’ from free plumes/jets for which the helical mode is usually dominant. It is found that higher surface curvature stabilises the temporal axisymmetric mode significantly, but only has moderate effects on the helical mode. The most temporally …

On the Interaction of Natural Convection and Mechanical Ventilation
Motivated by the need to ventilate buildings and prevent the accumulation of contaminants and excess heat, this thesis explores the interaction of natural convection and mechanical ventilation in an enclosure where fluid is supplied at a low level and extracted at a high level. A turbulent buoyant …
