مقاله Full scale plume rise modeling in calm and low wind velocity conditions : تی پی بین

خلاصه مقاله

A variety of models and software products are in use for computer simulation of pollutant dispersion for air pollution assessment. All of them need to calculate the so called effective stack height, but problems are encountered in calm and low wind velocity conditions. The present research aims at such meteorological situations.Based on a full scale numerical simulation, the plume rise has been investigated in sub-adiabatic and near-adiabatic conditions. The influence of the emission and stack parameters, the ground level air temperature, the temperature gradient of the atmosphere, and the surface wind velocity in the range from 0.0 to 1.0 m/s is studied.A computational fluid dynamics problem has been formulated and solved for planned combinations of meteorological conditions and emission parameters. For each numerical simulation the height of the plume center line and hence, the plume rise has been assessed. The results obtained have been used to work out new mathematical models for plume rise calculation.

Clean Technologies and Environmental Policy 2013

This journal publishes papers that aid in the development, demonstration, and commercialization of cleaner products and processes as well as effective environmental policy strategies. As its title suggests, the journal has two major thrusts: Clean Technologies and Environmental Policy. The Clean Technology thrust addresses the science and engineering of clean technologies. Moreover, it examines mathematical and computer-based methods and models for designing, analyzing, and measuring the cleanliness of products and processes. The Environmental Policy thrust covers research advances in scientific, social, behavioral, and economics disciplines that are relevant to complex environmental policy issues. In addition to research papers, the journal offers policy-oriented commentaries from world renowned leaders in environmental technology and policy research. It also features special issues focusing on topics of international concern.
