Publication: Aerodynamic flow investigations in an isothermal model of an afterburner
Abstract
Experimental and numerical investigations of the three-dimensional flowfields in an isothermal model of an afterburner are presented. Five-hole pilot probe measurements along the entire length of the model in three different azimuthal planes, allow the determination of three mean velocity components which provide comprehensive information to aid understanding of such complex flows. The numerical calculations are performed using a SIMPLE based algorithm with staggered grid arrangement. The standard k-e{open} model is used for physical modeling. The numerical results agree quite satisfactorily with the time-mean velocity measurements. The predicted turbulence kinetic energy contours have also been presented. © 1994 Springer-Verlag.
