Under the Air Pollution Modeling, three types of consultancy are undertaken

1.     Air Quality modeling – General air quality modeling for urban areas.

2.    Environmental Impact Assessment – This concerns with permanent/chronic dispersion of pollutants in the air due to existing industries or industrial expansion etc.

3.    Accidental Dispersion of pollutants in the atmosphere due to accidental leakages from industries and storages

Air quality modeling:

 Using in house developed fluidyn - PANACHE family of environmental software, fluidyn - PANACHE-PANAIR,  we undertake 3D simulation of general air quality in various weather conditions. For the benefit of  highway and environmental engineers, our study assesses, the impact of any changes in the existing infrastructure and  predicts the effects of pollution due to upcoming projects.

 Our study takes into account:

• Obstacles and high buildings;
• The influence of the vegetation and nature of the terrain on dispersion;
• Effects of the solar radiation and the ambient atmospheric conditions through a user-friendly interface.
• Low wind velocities by including the natural convection in the urban canopy.
• Production cycles of tropospheric ozone in the cities and their suburbs
• Evaluation of emissions of gaseous pollutants (Nox, CO, HC, etc.) or particulate matter (PM10, Pb, etc.) emitted by vehicles starting from the available traffic data on different highways and roads, for a standard fleet of vehicles.

 Input required for air quality modeling:

• type of roads: urban, rural, highways
• type of traffic: yearly average, hourly average or peak hour
• topography and ambient conditions: steep slopes, temperatures
• percentage of heavy lorries;
• average velocity of the traffic
• Crossroads, signals, traffic jams, stop signs

Environmental impact assessment:

 Environmental impact assessment consultancy, pertains to the atmospheric dispersion of industrial emissions in the air, released from punctual or continuous sources in the industrial sites. Such studies are undertaken using our software product fluidyn PANACHE-PANEIA.

Special features:

§         Our study takes into account all topographic and meteorological parameters.

§         Contrary to probabilistic methods such as the Gaussian method, Transoft uses a 3D deterministic approach to analyse the variation effects of each parameter independently with the help of a high precision numerical solver.

§         Project managers as well as decision makers can confirm or ensure that their industrial sites comply to the new set of regulations imposed by national regulations on atmospheric quality

EMERGENCY PLANNING AND RESPONSE:

 Under this head of consultancy, we analyse the consequence of releases and fire in process industry due to accidents. The release may occur from rupture or leak in pressurized or non-pressurized tanks, pipes, valves, joints, etc. This study is done using our software product fluidyn - PANACHE- PANEPR.

  Consultancy Service by application area

• Storage tank or pipe.
• Two-phase or liquid release.
• topography and ambient conditions: steep slopes, temperatures
• Dense gas dispersion with stratification and heat exchange with the ground.
• Deflagration and fire : 

                          1.Flame front propagation.
                               2.Radiation. 
                               3.Smoke formation.
