  • Regulatory dispersion modelling in Finland

    We present a review of regulatory atmospheric dispersion models and their application to environmental impact assessment (EIA) in Finland. The following regulatory models are available: the urban dispersion modeling system, models for dispersion of vehicular pollution, the air pollution information system, and the dispersion model for odorous compounds. All of these models are connected to a ...

  • Any liquid dispersing without foliation

    Dispersion is a process when small parts of one substance are distributed in thin liquid of another substance, without being dissolved in it. Such fluid call dispersing. In dispersion it is thin parts of substance is distributed in liquid part over time is depositing, and there comes the partial foliation. Therefore components of dispersion should be passed through GlobeCoreblending system ...

  • Biodiesel dispersion replaces diesel fuel

    Is that possible to find substitution to traditional diesel fuel? Until recently these question were asked by ecologists and diesel cars owners who are taking hard time in periodic rises in price of fuel. With the event of the biodiesel development the situation cleared up. It became clear to all that cheap, qualitative and environmentally friendly biodiesel was born and started winning surely ...

  • The Atmospheric Dispersion Modelling System (ADMS): comparisons with data from the Kincaid experiment

    In order to test the ability of a model its results must be compared with experimental data; hence validation work is an essential part of the development of any model. This paper presents the results of a validation study of the UK Atmospheric Dispersion Modelling System (UK-ADMS) version 1.06, a short-range dispersion model, against the results of the Kincaid field experiment. Predictions of ...

  • Validation of the Demokritos dispersion modelling system based on the Indianapolis experiment

    To assess the ability of a model to simulate atmospheric dispersion, its performance must be tested using data from real field experiments. This paper presents the results of a validation study of the atmospheric dispersion model Dispersion over Complex Terrain (DIPCOT) against data from the Indianapolis field experiment. Three different modules of the dispersion code are examined a puff model, a ...

  • Assessing meteorological uncertainties in dispersion forecasts using a NWP Ensemble Prediction System

    The use of ensembles of meteorological forecasts is explored in the context of dispersion modelling for emergency-response applications such as nuclear accidents or chemical releases. Specification of meteorology is often a major source of uncertainty in dispersion predictions. The ensemble methodology, routinely used in Numerical Weather Prediction (NWP), is followed in which multiple ...

  • Dispersion Modeling as a Tool to Establish Odor Policy

    Odor control is a critical component of the Orange County Sanitation District’s (the Sanitation District) planning and operations. The Sanitation District’s two wastewater treatment plants (Fountain Valley, CA and Huntington Beach, CA) were isolated when originally constructed in the middle of the 20th century, but are now surrounded by high-density residential areas as well as highly used ...

  • Raman frequency dispersion studies of substituted polythiophene films

    Styryl substituted terthiophene species have been used to produce neutral polythiophene species which show distinct Raman frequency dispersion. The polythiophene line B band shows dispersion values of: -0.12, -0.07, -0.1 cm−1 nm−1 for the phenyl, para-methoxy phenyl and para-cyano phenyl systems respectively. This is smaller than the dispersion values reported for polythiophene presumably because ...

  • An urban scale model for pollutant dispersion in Rome

    A Gaussian model software (Atmospheric Dispersion Model System?ADMS-Urban) is used to forecast the carbon monoxide concentrations in the Urban Boundary Layer (UBL) of the city of Rome, Italy. The simulations refer to 14 days during 2002. Two data set inputs were considered in order to evaluate the urban background concentration and the effects of the main roads surrounding the monitoring ...

  • Dispersion modelling near tunnel exits: simulation and measurements

    Measurements of car exhaust gases were made in May/June 1995 in the vicinity of the Bielefeld tunnel. CO and NOx from car exhausts were measured to allow comparison with a model simulation. Ozone was also measured. These measurements were made using commercial continuous analysers. A valve control system was used to investigate the dispersion of the trace gases. This allowed measurements at ...

  • Longitudinal dispersion in open channel flow with suspended canopies

    Suspended canopies can cause flow disturbances such as reducing velocities within the canopy, and increasing flow beneath the canopy. Flow modifications by canopies dramatically affect the fate and transport of sediment, nutrients, contaminants, dissolved oxygen, and fauna in aquatic systems. A three-zone model is presented here to predict the longitudinal dispersion coefficient by simplifying ...

  • Keeping the Increasing Complexity of Air Dispersion Modeling in Check

    Driven by advances in scientific knowledge, tightening and constantly changing regulations, and higher-resolution raw data, environmental modeling is demanding more and more from EH&S professionals and their computers. AERMOD run times for large projects are measured in days rather than minutes and terrain data file sizes routinely exceed 100 MB. Modelers can increase productivity and keep ...

  • A new microturbine-based dispersed generation scheme

    Almost all of the commercial microturbine-based dispersed generation systems today are composed of a high-speed permanent-magnet alternator and a diode rectifier-PWM inverter pair. A dispersed generation scheme made up of a microturbine, an induction generator, and a diode rectifier-PWM inverter pair is introduced in this paper. A complete model for the self-excited squirrel-cage induction ...
