Numerical Simulation of Turbulent Buoyant/Heavy Cloud Motion

For the National Institute of Standards and Technology, a multi-dimensional numerical code for the rise and dispersion of massive fire plumes was developed based on vortex and transport element methods. Various buoyant plume phenomena, such as: plume bifurcation, plume penetration of inversion layer, detailed entrainment and mixing patterns, and dense smoke cloud spreading in complex terrain, are quantified.  The model has been used for the study and prediction of the dispersion of the Kuwaiti fire plumes.  Lately, the model has been extended to the simulation of puff lift-off from the ground. The puff stem formation, puff lift-off, and vortex ring formation, as well as the detailed entrainment process are described and compared well with field experiments.  Modifications of the code (MARS) to simulate practical mixing and reaction problems are in progress.  The code simulates the time-dependent high-Reynolds number turbulent mixing and transition without using conventional turbulent modeling procedures.  For two-dimensional problems, this computational code can be executed on a PC Pentium.

Dust emission and deposition from a Cement Plant

Dispersion calculation was carried out by one of our staff for a cement plant in Egypt under the auspices of the Supreme Council of Universities. A complete set of meteorological measurements were collected and analyzed.  The deposition rates of cement dust were calculated and the options for the pollution control were provided.

Smoke Emissions from a Cotton Seed Processing Plant

Currently working on a project for Delta-Pine cotton-seed processing plant to devise engineering ways of reducing smoke emissions.  The project involved developing a detailed process flow sheet of the plant, collecting particle emissions from different locations, carrying-out a detailed mass and energy balance, data analysis, and suggesting ways to reduce the emissions.

Evaluation of Afterburner

For a cogeneration plant, we evaluated the effectiveness of an afterburner to destroy the benzene emitted by a 42 MW diesel engine set. We correlated kinetic data published for various pressures, temperatures and compositions. Based on this correlation, we identified air preheat and excess air settings that would minimize emission.

Catalyst of NO-CO Reaction in Exhaust

For a chemical company, we investigated the use of a proprietary metalloceene to catalyze the NO-CO reaction in car exhaust. The catalyst was sublimated in a fluidized bed heater and injected hot at various locations in the exhaust line. Recommendations were made on the suitability of this catalyst to automotive applications.
