Experimental Flow Investigation of a Truncated Ideal Contour Nozzle [PDF]
, 2006 Various tests showed a significant side load peak for low nozzle pressure ratios during engine start-up and shut down phase. DLR Lampoldshausen carried out tests to examine the flow field in a truncated ideal contour nozzle for low NPR.

Numerical 3D study on the influence of spanwise distribution of tubercles on wings for UAV applications [PDF]
MATEC Web of Conferences, 2019 In this work, a 3D numerical study on the influence of the spanwise distribution of tubercles for UAV applications is presented. The idea of using tubercles in aeronautics comes from the humpback whale (Megaptera novaeangliae) which has a characteristic ...

Reactant Jetting in Unstable Detonation [PDF]
, 2009 We note the common existence of a supersonic jet structure locally embedded within a surrounding transonic flow field in the hitherto unrelated phenomena of unstable gaseous detonation and hypervelocity blunt body shock wave interaction. Extending prior

Comparative analysis of alternative fuels in detonation combustion [PDF]
, 2016 Detonation combustion prominently exhibits high thermodynamic efficiency which leads to better performance. As compared to the conventionally used isobaric heat addition in a Brayton cycle combustor, detonation uses a novel isochoric Humphrey cycle which
