Reduction of Diesel Emissions from Heavy Duty Diesel Vehicles This project is an experimental study aimed at evaluating emission reduction strategies for diesel powered school buses and heavy duty diesel vehicles (HDDV’s). A variety of fuel types, mixtures, additives and exhaust treatment systems will be tested to determine the optimum configuration for various school bus duty cycles (e.g. rural, urban, etc.). A team of Rowan University faculty with substantial research expertise in combustion, chemically reacting systems, membrane separations and air pollution will monitor the testing, analyze the data and report the results. In addition to the school bus testing, a parallel study will be conducted to review and compare idle reduction technologies for HDDV’s.
Precipitation/Crystallization – Using laser diagnostic equipment to examine chord length distributions in stirred-tanks.
Membrane Separations – Application of ultrafiltration and microfiltration to industrial fluids.
Supercritical Fluid Extraction – Examination of new applications of supercritical fluids to recovery of high value added materials
Selective Adsorption – Solid phase extraction is being applied to industrial fluids to recovery high value added materials. New and innovative solid phase and water soluble polymers are being employed.
Chemical Reaction Kinetics in Combustion.
In this research area, we are examining the chemistry of gaseous pollutant formation and destruction related to combustion processes. Fuel nitrogen compounds are of particular concern because they are the principal source of Nox in the exhaust gases from combustion devices. This research is focused on obtaining reaction pathways for combustion of nitrogen contained in fuel. Both theoretical and experimental work is being conducted.
Fluidized Bed Incineration.
Research is being conducted to examine the use of fluidized bed technology to incinerate liquid or solid wastes. In addition, ongoing research examines volatile combustion in fluidized beds. The goal of this research is to incinerate waste and burn coal in an environmentally acceptable manner. This includes maximizing the destruction of the waste or fuel and recovering the heat from this process. Currently the focus of the project is on the combustion reactions within the fluidized bed. We have identified that sand, a typical bed material, can inhibit the combustion reaction at low temperatures by a free radical termination reaction. The effects of surface area, surface type and concentration of chemical species on the inhibition of combustion are currently being investigated.
Multiphase Flow Dispersion
systems are used to increase the interfacial area and improve the rates of mass and/or heat transfer between one or more phases. The fundamental fluid mechanics of dispersed phase systems are being investigated to determine the rate of breakage and coalescence/agglomeration of bubbles drops and solid particles.
