Plume rise model for merging plumes
2023To correctly reproduce the dispersion of pollutants the plume rise modeling is fundamental to obtain the injection height, i.e. the altitude at which the majority of the smoke burden is released into the surrounding atmosphere, because from this depends how the plume from fire emissions are ultimately transported In 2013 ...

Plume–Plume and Plume–Surface Interactions of Micronozzle Clusters in Vacuum
AIAA JournalPlume flow features and performance characteristics of micronozzles arranged in a cluster configuration operating under vacuum exit conditions are analyzed utilizing the direct simulation Monte Carlo (DSMC) method. A comparison of the plume behavior of single bell-shaped and conical nozzles is carried out to establish a baseline for evaluating cluster ...

Building downwash of plumes and plume interactions
Journal of Wind Engineering and Industrial Aerodynamics, 1995This paper presents a number of wind tunnel measurements of building induced downwash effects on the plume in a neutrally stable boundary layer. Vertical and horizontal profiles of mass concentrations of the exhausts from stacks on a rectangular model building were measured downwind of the buoyant source in the near wake.

Mantle Plumes and Their Interactions
2022Hotspots are regions of intraplate volcanism or especially strong volcanism along plateboundaries, and many of them are likely caused by underlying mantle plumes – localizedhot upwellings from deep inside the Earth. It is still uncertain, whether all plumes or justsome of them rise from the lowermost mantle, and to what extent and where theyentrain ...

Physical Review Letters, 1992
We present an experimental study of thermal plumes growing in Hele-Shaw cells which shows the existence of new objects, analogous to Saffman-Taylor fingers, for which the thermal boundary layer plays the role of the interface.

Plumes and Concentric Plume Traces of the Eurasian Plate
Nature Physical Science, 1973There are many more lines of volcanoes which increase in age from one end to the other than can be due to chance. One explanation which has been proposed is that volcanoes form overheated columns or plumes rising from deep in the mantle at fixed locations1.

Volcanology![Figure][1] CREDIT: ASSOCIATED PRESS, COLT SNAPP Monitoring remote eruptions—such as that of Pavlof Volcano, Alaska, in 2016—is challenging. Fee et al. found that the height of the ash plume during the Pavlof eruption could be inferred from sound waves detected by ...

Chemical signals are primarily distributed throughout aquatic environments by processes that are affected by turbulence. Turbulence continually stirs and mixes chemical odorants into complex, filamentous structures that are sampled by organisms. These odorant signals are critical for survival and/or reproductive success of most aquatic animals, and the
