Hydrodyn-AIRSOFT

It is an absolute user friendly system, developed specifically for environmental engineers, who may not have much exposure to numerical concepts in data creation , calculation and analysis.

What is AIRSOFT?

Hydrodyn-AIRSOFT is a self-contained three-dimensional fluid dynamics software package designed to simulate pollutant spread into the atmosphere due to various types of emissions from stacks, vehicles and other sources. The software takes into account the topographical parameters.

Features

• Excellent Pre-Processing Facilities.


• High precision finite volume method for solving the governing equations.


• 3-D models for flow and pollutant transport.


• Possibility of imposing varied flow boundary conditions.


• Post-processing and online help facilities.


• Accessible and user-friendly menu for non-specialists.


• Water bodies, forests, fields, temperature and roughness.


• User interface for defining topographical features, meteorology, multiple emission sources.

Application Areas

Industrial and Road emissions

• Simulation of atmospheric flow around the complex shape of buildings and chemical units. Heavy gas dispersions in tunnels.
• Leakage source.
• Fire and chemical reactions
• Simulation of temperature variation

Impact evaluation

• Plumes from a single or multiple stacks along with vehicular or other industrial exhaust.
• Particulate emission from chimneys
• Chemical reactions related to plume gases
• Exhaust dispersion of vehicular traffic
• Waste water plant gases
• Analysis of different emissions, meteorological and topographical parameters on the plumes and sensitivity analysis for choosing the appropriate emission control device.

Choice of site monitoring devices

• In general pollution data monitoring devices are expensive and identifying the monitor sites physically are difficult based on the available data. Hence, AIRSOFT can be used for identifying the sites as well as calibration of concentration field.

Wind Velocity Field

• Simulation of atmospheric flow around high-rise buildings and undulated terrain
• Simulation of wind fields from data stored at meteorological stations

Urban Air Quality

• Simulation of Urban air quality
• Modules for various pollutants like CO, SO2, NOx etc for traffic emission can be studied.
