Investigation on a new method of adaptive drag reduction and nonablation thermal protection system for hypersonic vehicles
hypersonic drag reduction heat flux jet aerospike numerical simulation
2013/9/2
A new adaptive drag reduction and nonablation thermal protection method named Telescopic Selfaligning JetSpike (TSAJS) is proposed to improve the conventional spiked method employed in hypersonic v...
Polymer Maximum Drag Reduction: A Unique Transitional State
Polymer Maximum Drag Transitional State
2011/9/5
The upper bound of polymer drag reduction is identified as a unique transitional state between laminar and turbulent flow corresponding to the onset of the nonlinear breakdown of flow instabilities.
The influences of wall Lorentz force and field Lorentz force on the cylinder drag reduction
Cylinder wake Flow control Lorentz force Electromagnetic control
2012/2/29
In this paper, the effects of Lorentz force on drag reduction for a circular cylinder have been studied experimentally and numerically. Based on its effects on drag reduction, the Lorentz force is fou...
