Abstract

For a new type of mixer and diffuser and aircooled stabilizator integration structure

a threedimensional numerical simulation model based on the N-S equation was created. Through numerical simulation

the flow field

flow resistance characteristics and mixing characteristics of different aircooled radial stabilizator opening angles in the mixer and diffuser were obtained. The results show that

the recovery coefficient declines as the aircooled radial stabilizator opening angle increases; the flow resistance cofficient and pressure loss coefficient of the mixer and diffuser increases with the growing aircooled radial stabilizator opening angle. Around the exit section of the mixer and diffuser

the total pressure recovery coefficient declines as the aircooled radial stabilizator opening angle increases

the difference between the maximum and the minimum values is 0.0032

and the thermal mixing efficiency increases with the whole range of 0.7268~0.8857.
