Abstract (en)
A vortex generator (10), especially for a fuel injection system of a gas turbine, comprises a base area (11) and a vortex generator body (10a) extending in a tapering fashion from said base area (11) with a predetermined height (h1+h2). A rapid fuel-air mixing at allowable pressure drops for higher firing temperature gas turbines and within short burner-mixing length or time scales is achieved by said vortex generator body (10a) forming at least two partial vortex generators (VG1, VG2), whereby each of said at least two partial vortex generators (VG1, VG2) has its own trailing edge (12a, 12b).
