Wind tunnel experiments: Atmospheric dispersion prediction methods for environmental assessment using environmental impact assessment methods.
Wind tunnel experiment - Environmental assessment
It can be utilized for various environmental impact assessments, including environmental assessments of power plants such as thermal and geothermal, decentralized power sources, and the diffusion of heat and exhaust gases from heat islands.
Wind tunnel experiments and environmental assessments refer to one of the atmospheric dispersion prediction methods established by the Environmental Impact Assessment Act. This involves placing models of terrain and structures inside a wind tunnel to recreate air flow and conduct experiments to predict the dispersion of exhaust gases released from power plants and waste incineration facilities (cleaning plants). This method is described in the "Guidelines for Environmental Impact Assessment Related to Power Plants," which serves as a guideline for implementing environmental assessments issued by the Ministry of Economy, Trade and Industry. By precisely controlling the temperature and flow velocity of the airflow within the wind tunnel, it is possible to replicate the actual atmospheric flow conditions and measure the behavior of gases and the concentration of smoke dispersion. **Applications** - Airflow analysis and dispersion analysis for various power plants, including thermal, nuclear, and geothermal. - Atmospheric environmental impact assessments in urban areas (such as decentralized power sources and urban warming effects). - Dispersion conditions of exhaust gases released from incineration facilities (cleaning plants). - Visualization experiments of flow fields around modeled buildings. **Features** - Precise reproduction of "temperature distribution, airflow distribution, and airflow turbulence" in the atmosphere. - Visualization of flow fields using smoke and lasers. - Capability to address complex structures that are difficult to replicate in simulations. *Please feel free to contact us through our company website.*
