Study of direct gas injection into stagnation zone of blunt nose at hypersonic flow
(American Institute of Aeronautics and Astronautics, 2021-07-28)
Direct gas injection in the shocked or compressed region has importance in many applications from drag control to ignition and pressure gain combustion. This numerical study is focused on direct light gas injection into ...
Drag control by hydrogen injection in shocked stagnation zone of blunt nose
(IOP Publishing, 2021)
The main motivation of the current study is to propose a high-pressure hydrogen injection as an hybrid active flow control technique in order to manipulate the flow-field in front of a blunt nose during hypersonic flight. ...
Numerical investigation of detonation propagation through small orifice holes
(Sciendo, 2021)
Seeking to better understand the physical phenomena underlying detonation wave propagation
through small holes (especially the phenomenon of detonation re-initiation or its failure), we investigated
the propagation of a ...
Effects of freestream disturbances in front of spiked blunt nose at hypersonic flow
(Council of European Aerospace Societies, 2021)
The effects of high frequency slow and fast acoustic wave freestream disturbances are modelled in front of
pulsating bow shock formed at spiked blunt nose in hypersonic flow. These disturbances are introduced as
time-dependent ...
Numerical study of an aerospike nozzle in retropropulsion
(Council of European Aerospace Societies, 2021)
The primary motivation of this numerical study is to explore the feasibility of drag enhancement using aerospike
nozzle for retropropulsion in hypersonic flow. An external expansion contoured aerospike nozzle with design ...
