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 ...
A concept of aerospike nozzle for cold spray additive manufacturing: towards a potential solution for preventing the issue of clogging
(ASM International, 2023-05-22)
The clogging, a frequent gas passage deformation phenomenon because of powder accumulation on inner nozzle wall, is a major issue in long duration Cold Spray (CS) operations and a major challenge for Cold spray technology ...
Investigation of a modified circular nozzle for cold spray applications
(ASM International, 2023-05-22)
The current work numerically evaluates the efficacy of a coflowing nozzle for cold spray applications with the aim to mitigate nozzle clogging by reducing the length of its divergent section. The high-pressure nitrogen ...
