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 ...

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.

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.

Diurnal solar heating produces an unstable warm zone just off the bottom of the inshore regions of a salt lake. The warm water rises in plumes in which brine shrimp become entrapped through apparently negative photokinetic behavior. The plumes of concentrated shrimp resemble those composed of insects in air.

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

Plume flow and plume impingement in space technology
Progress in Aerospace Sciences, 1991Abstract Rocket thrusters of various types are the common means of propulsion in space technology. In the space vacuum the exhaust gases form a large free jet, called a plume, which can impinge on neighbouring surfaces. The impingement effects, often unavoidable due to the unrestricted spreading of the gas, are disturbing forces and unwanted heat ...

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
