Trapped vortex counter flow combustor for gas turbine

A trapped vortex counterflow combustor for a gas turbine includes a first domed structure having a plurality of first domed vortex driver airflow openings for providing a first vortex generating intermediate airflow therethrough to a trapped vortex cavity. The second domed structure is disposed downstream of the first domed structure and includes a plurality of second domed vortex driver airflow openings providing a first vortex-generating outer airflow therethrough to the trapped vortex cavity and a plurality of primary driver airflow openings providing a second vortex-generating outer airflow therethrough to the trapped vortex cavity. A plurality of primary driver airflow openings provide a primary driver airflow therethrough radially inward of the trapped vortex cavity. 一种用于燃气涡轮的驻涡逆流燃烧器，包括第一圆顶结构，该第一圆顶结构具有多个第一圆顶涡流驱动器气流开口，用于提供穿过其至驻涡腔的第一涡流产生中间气流。第二圆顶结构布置在第一圆顶结构的下游，并且包括多个第二圆顶涡流驱动器气流开口和多个初级驱动器气流开口，多个第二圆顶涡流驱动器气流开口提供穿过其至驻涡腔的第一涡流产生外气流，多个初级驱动器气流开口提供穿过其在驻涡腔的径向内侧的初级驱动器气流。
