Nieh, S

This report focuses on the discussion of cold flow measurements and mathematical modeling of the vortex combustor (VC). A parallel research project on the combustion tests of a 2-4 MB/H proof-of- concept VC has been conducted by the Naval Civil Engineering Laboratory. This final report is divided into seven chapters: Chapter 1 discusses the concept and advantages of the VC, and the technical approach to develop and demonstrate this VC concept. Chapter 2 describes in details the instrumentation and test apparatuses of the VC cold models. Chapters 3 and 4 discuss the measured results of gas flow field and particle flow field. Development and atomization tests of CWF nozzles are also presented in this chapter. Chapter 5 provides the basics governing equations and numerical methods for the five sub-processes in the VC. Chapter 6 gives the calculated results of validation tests of the computer program and the results of numerical simulation of the VC processes. Finally, Chapter 7 concludes the efforts of cold flow modeling study of the VC. 52 refs., 101 figs., 39 tabs.
