Explosive volcanic jets present an unusual dynamic situation of reversing buoyancy. Their
initially negative buoyancy with respect to ambient fluid first opposes the motion, but can …

The lattice Boltzmann equation method in two dimensions was used to analyse natural
convective flows. The method was validated with experiments in an open cavity with one of …

Laboratory experiments and numerical calculations are used to study how a laminar thermal
plume deforms and penetrates a buoyant and viscous layer, which serves as an analog for …

We use a four-dimensional variational data assimilation (4D-VAR) algorithm to observe the
growth of 2-D plumes from a point heat source. In order to test the predictability of the 4D …

The heat transfer characteristics of a transformer using both standard mineral oil and
nanodiamond oil was investigated numerically and compared to experimental …
