Quantification of plume opacity by digital photography.
The United States Environmental Protection Agency (USEPA) developed Method 9 to describe how plume opacity can be quantified by humans. However, use of observations by humans introduces subjectivity, and is expensive due to semiannual certification requirements of the observers. The Digital Opacity Method (DOM) was developed to quantify plume opacity at lower cost, with improved objectivity, an...
متن کاملMulti-Wavelength Laser Opacity Study of a Hybrid Rocket Plume
An instrumentation system was developed to measure the opacity of a hybrid rocket plume as a function of optical wavelength. The source consisted of collineated beams from two lasers, providing seven wavelengths in a single probe beam. Detection was accomplished with a spectrograph equipped with a photodiode array. Previous work with a two-wavelength system demonstrated the ability to follow th...
متن کاملField Testing of the Digital Opacity Method to Quantify Plume Opacity
U.S. Environmental Protection Agency (USEPA) established Method 9 as a standard method to quantify plume opacity. However, there are issues about the subjectivity of such method . The appearance of the plume to human observations can be affected by many factors, such as the angle of the sun, the time of the day and the geographic location of the source . A new digital photographic method, Digit...
متن کاملnumerical simulation of plume rise in neutral atmospheric stability condition
introduction air pollution has harmful effect on human health and the environment. accordingly, considerable effort has been put to analyze the air pollutants. one important issue is the spatial distribution of these pollutants. dispersion of the pollutants released from sources on the ground is mostly driven by the planetary boundary layer where turbulent flow causes mixing of the content of t...
