   Sammanfattning : The consequences of bladder outlet obstruction (BOO) with respect to detrusor hypertrophy, structural and functional changes, and obstruction-induced detrusor overactivity were investigated in vivo and in vitro utilizing various animal models. Possible pathophysiological pathways and therapeutic approaches were tested by drug treatment and the use of knockout models. LÄS MER

7. 10. Multimethod aerodynamic research of engine-realistic turbine rear structures

   Författare :Valentin Vikhorev; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; particle image velocimetry; vane lean; pressure taps; enginerealistic; engine-mount recess; European Union EU ; hot-wire anemometry; outlet guide vanes; oil-film visualization; multi-hole probe; turbine exhaust case; bump; turbine rear frame; computational fluid dynamics.; Clean Sky 2; experimental multimethod approach; Horizon 2020; EATEEM; turbine rear structure; low-pressure turbine;

   Sammanfattning : Despite the significant advancements in aircraft engine technology over the past years, the aerodynamics of engine-realistic turbine rear structures (TRS) remain largely unexplored. The TRS, a structural and aerodynamic component situated downstream of the low-pressure turbine (LPT), plays a pivotal role in engine aerodynamic performance, deswirling the LPT flow to maximize the engine thrust.
