1. 1. Study of tip clearance flows

   University essay from KTH/Flygdynamik

   Author : Camille Fournis; [2018]
   Keywords : turbomachine; compressor; tip leakage flow; vortex; turbomaskin; kompressor; gapflöde; virvel;

   Abstract : The tip leakage vortex is responsible for the generation of stagnation pressure losses inside the compressor along with the outbreak of rotating stall and surge. The current paper analytically proved that a part of the losses is proportional to the vortex circulation squared. READ MORE

3. 2. An Experimental Study of the High-Lift System and Wing-Body Junction Wake Flow Interference of the NASA Common Research Model

   University essay from KTH/Optimeringslära och systemteori

   Author : Desirée Brundin; [2017]
   Keywords : Common research model; wind tunnel experiments; subsonic flow; wing-body junction; commercial aircraft; Cobra Probe measurements; high-lift control systems; flow interference; drag estimate.;

   Abstract : This thesis investigates the turbulent flow in the wake of the wing-body junction of the NASA Common Research Model to further reveal its complex vortical structure and to contribute to the reference database used for Computational Fluid Dynamics validation activities. Compressible flows near two wall-boundary layers occurs not only at the wing-body junction but at every control surface of an airplane, therefore increased knowledge about this complex flow structure could potentially improve the estimates of drag performance and control surface efficiency, primarily for minimizing the environmental impact of commercial flight.
