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 ...
