查询词典 trace

A large range of IRZ and intense fluctuating velocity area around the boundary of IRZ is measured and thought to be important to keep the excellent ignition and combustion characters of the new kind swirl burner. Together with temperature trace method, different structure and operation parameter of the burner are studied in this paper about their effects on turbulent and mixing characters of swirling jet. The structure variation includes different blade angle, use of central gear shape baffle, variable outer length and angle of lean primary air outlet, use of wedge outlet of lean primary air.
