Novel mechanism of instability control using tapered spike in hypersonic flow
(American Institute of Aeronautics and Astronautics, 2021-08-02)
A forward facing spiked blunt nose in high-speed flows is associated with pulsating flow behavior of varying amplitudes depending on spike-nose and length, the forebody geometry and flow conditions. A tapered spike has ...
On unsteady flow analysis of a round spike blunt nose afterbody in mach 6 flow
(IOP Publishing Ltd, 2021)
An aerospike, in front of a blunt body, has largely been deemed as a key passive control device for effectively reducing the wave drag and aerodynamic heating associated with high-speed flows. In addition, it has been ...
Pulsating flow investigation for spiked blunt-nose body in hypersonic flow and its control
(American Institute of Aeronautics and Astronautics, 2021-01)
An aerospike, as a technique for drag reduction and heat transfer in high-speed flows, is
associated with instabilities. To understand the pulsating flow behavior in front of forward
facing spiked blunt nose, numerical ...
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 ...
Mach number dependence of flow instability around a spiked body
(AIP Publishing, 2023-05-05)
A forward-facing aerospike have been identified as a passive flow control device for enhancing the aerodynamic efficiency and reducing the heat transfer in high-speed flows. In addition, it has been reported that the ...
