The aim of the present study is to simulate CO dispersal usingComputational Fluid Dynamics (CFD). Due to the similarity in physical configurationto the watercraft exhaust system, the canonical problem of a singleJet In Cross Flow (JICF) is chosen as a validation case. Simulation of the JICFaffords insight into the adequacy of the computational methodology before themethodology can be extended to simulate the present problem. Watercraft exhaustsystems include dual exhaust ports, and hence, the methodology usedto simulate the single jet is extended to a dual-jet system. Results show apronounced interaction of the flow structures developed in the flow field. Further,the jets in the dual-jet configuration do not penetrate the cross flow tothe extent that the single jet does. This phenomenon will prove important inthe design and control of systems where multiple jets are used for optimummixing. The watercraft exhaust system is simulated and the results presentedshow that the prevailing large-scale flow structures affect the dispersal of CO.Based on these results, three ways of mitigating CO dispersal are proposed. 2008-08-28 English text University of Cincinnati / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ucin1212173987 http://rave.ohiolink.edu/etdc/view?acc_num=ucin1212173987 unrestricted This thesis or dissertation is protected by copyright: some rights reserved.
