We present three-dimensional hydrodynamic simulations of the interaction of aslow wind from an asymptotic giant branch(AGB) star and a jet blown by anorbiting companion. The jet or "Collimated Fast Wind" is assumed to originatefrom an accretion disk which forms via Bondi accretion of the AGB wind or Rochelobe overflow. We present two distinct regimes in the wind-jet interactiondetermined by the ratio of the AGB wind to jet momentum flux. Our results showthat when the wind momentum flux overwhelms the flux in the jet a moredis-ordered outflow outflow results with the jet assuming a corkscrew patternand multiple shock structures driven into the AGB wind. In the opposite regimethe jet dominates and will drive a highly collimated narrow waisted outflow. Wecompare our results with scenarios described by Soker & Rappaport (2000) andextrapolate the structures observed in PNe and Symbiotic stars.Comment: 22 pages, 8 figures, submitted to Ap
