- Abstract
- Measurement of optical properties and particule agglomeration of smoke from Alberta Sweet blend mix crude oil fires were made using a one cubic meter aging/dilution chamber. Measurements were made at ambient temperature simulating conditions in dilute smoke plumes away from the fire and at 100 deg C which simulates temperature conditions within several flame heights above the burning crude oil. Measurements of light transmission at three different wavelengths through the smoke collected in the chamber proved that the specific extinction coefficient of the carbonaceous agglomerate particles in the smoke is independent of the agglormerate size. These data are used as input to a calculation of smoke particle settling from the fire plume and deposition remote from the fire site. The calculation uses a large eddy simulation method to predict characteristics of wind blown buoyancy driven fire plumes. The calculation is capable of displaying the major features of smoke transport from the site of crude oil combustion. The process of smoke particulate settling from the plume is considered in detail by tracking representative smoke particules in the calculation. Results of example calculations are presented that demonstrate important features of the method.
