This book was released on 2018-06-27 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental results from a study of the effects of passing wakes upon laminar-to-turbulent transition in a low-pressure turbine passage are presented. The test section geometry is designed to simulate the effects of unsteady wakes resulting from rotor-stator interaction upon laminar-to-turbulent transition in turbine blade boundary layers and separated flow regions over suction surfaces. Single-wire, thermal anemometry techniques were used to measure time-resolved and phase-averaged, wall-normal profiles of velocity, turbulence intensity, and intermittency at multiple streamwise locations over the turbine airfoil suction surface. These data are compared to steady state, wake-free data collected in the same geometry to identify the effects of wakes upon laminar-to-turbulent transition. Results are presented for flows with a Reynolds number based on suction surface length and exit velocity of 50,000 and an approach flow turbulence intensity of 2.5 percent. From these data, the effects of passing wakes and associated increased turbulence levels and varying pressure gradients on transition and separation in the near-wall flow are presented. The results show that the wakes affect transition both by virtue of their difference in turbulence level from that of the free-stream but also by virtue of their velocity deficit relative to the freestream velocity, and the concomitant change in angle of attack and temporal pressure gradients. The results of this study seem to support the theory that bypass transition is a response of the near-wall viscous layer to pressure fluctuations imposed upon it from the free-stream flow. The data also show a significant lag between when the wake is present over the surface and when transition begins. The accompanying CD-ROM includes tabulated data, animations, higher resolution plots, and an electronic copy of this report.

Available in PDF, EPUB and Kindle. Book excerpt: An experimental and computational study has been undertaken to investigate the interaction between a transverse circular sonic jet and a Mach 6.7 cross flow on a sharp-edged flat plate with particular emphasis on the influence of the oncoming boundary layer state on the flowfield characteristics. This was achieved by generating 'steady' wedges of turbulent flow in the otherwise laminar oncoming boundary layer. The first component of this investigation involved an experimental investigation of transitional phenomena on a sharp-edged flat plate in a free-piston shock tunnel. Four test conditions were examined spanning a unit Reynolds number range of 3.16- 7.82x106m-1 and a flow enthalpy range of 2.86-3.20MJ/kg. The onset of boundary layer transition and the characteristics of the dynamic structures within the transitional region for these conditions were consistent with previously reported results. The main investigation examined the response of the jet interaction (JI) flowfield in response to 'mixed' laminar/turbulent oncoming flow. The test condition used for this work had a unit Reynolds number of 4.86x106m-1 and a flow enthalpy of 3.02MJ/kg. The interaction was generated by nitrogen gas from a circular 3mm diameter sonic nozzle at total jet-to-freestream pressure ratios of between 237 and 412. The upstream separated region was found to be very sensitive to the upstream boundary layer state with simultaneous regions of laminar-like and turbulent-like separation. The shock structures immediately around the expanding plume were relatively insensitive, although some change in shape was noted. Highly variable localised regions of high heat transfer were observed around the injector. The Computational Fluid Dynamic (CFD) study found a previously unexplained coupling between the upstream and downstream vortex structures. It also demonstrated that the forces and moments generated by the jet could be strongly influenced by both the location and width of the boundary layer turbulence relative to the size of the interaction. The agreement between the experimental and computational surface pressures results was good. The heat transfer comparisons were limited due to the inability of the steady-state code to accurately model the large scale transient structures present in the physical flowfield which contribute to this process.
