Among a variety of design requirements, reducing the drag and aeroheating on hypersonic
vehicles is the most crucial one. Unfortunately, these two objectives are often conflicting. On …

One key feature that distinguishes the flowfield around vehicles flying in supersonic and
hypersonic regimes is the bow shock wave ahead of forebody. The severe drag and …

Aerodynamic drag and heat reduction effectivity of the aerospike attached to the blunt-body
at various aerospike semi-cone angles (θ S)⁠, lateral injection from the aerospike stem, and …

The present paper reports a numerical simulation of the supersonic/hypersonic unsteady
flow over a spiked blunt body. Axisymmetric compressible Navier-Stokes equations are …

The assumption that a zero-incidence flow around bodies of revolution is axisymmetric has
been broadly adopted by many researchers, even for cases where the flow around such …

SENSITIVITY to initial conditions is a well-known phenomenon in all speed regimes, and it is
often associated with hysteresis. At low speeds, flow past airfoils shows different solutions …

Among a variety of design requirements, reducing the drag and aeroheating on hypersonic
vehicles are the most crucial. Unfortunately, these two objectives are often conflicting. On …

Enormous research has taken place in the recent year in order to reduce the aerodynamic
drag and heating resulting from high speed and shape of the blunt cone for hypersonic …

A series of high-fidelity, three-dimensional simulations has been performed to investigate
hypersonic phenomena encountered in the HIFiRE Flight 1 and Flight 2 experiments. The …

Reentry space vehicles, reusable launch vehicles, hypersonic and supersonic missiles are
employed with blunt body as a fore body to decelerate the vehicle and to avoid aerodynamic …
