DESIGN AND STUDY OFANNULAR COMBUSTOR FOR MICRO TURBINE

The annular combustor has some characters such as compact structure, high combustion efficiency in despite of complex structure, so it is considered the development direction of the micro turbine combustor in the future. In this paper a 100kW classic micro turbine annular combustor was designed. The basal geometrical size of the combustor is determined by the method of combustion efficiency, the method of total pressure recovery coefficients and the method of the prototype magnified. On the primary design three-dimensional reactive flow was studied numerically. The characters of the flow and the temperature distribution were analyzed. The consistency of numerical results and design data indicates that the design in this paper is satisfied the design requirement.
