Bodies having Minimum Pressure Drag in Supersonic Flow-Investigating Nonlinear Effects
Minimum Pressure Drag Supersonic Flow-Investigating Nonlinear Eff ects
2015/7/2
One of the most interesting problems in supersonic aerodynamics has been to find profile shapes that have minimum pressure drag, subject to a set of geometric constraints.Considerable work...
Out of a host of experimental aerodynamic data available for the DLR-F6 configura tion a set of reference test cases has been chosen for the second AIAA drag prediction workshop.
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.
Drag force on a sphere moving towards an anisotropic super-hydrophobic plane
Drag force sphere super-hydrophobic
2011/8/26
We analyze theoretically a high-speed drainage of liquid films squeezed between a hydrophilic sphere and a textured super-hydrophobic plane, that contains trapped gas bubbles. A superhydrophobic wall ...
Drag Coefficient of a Spherical Particle Attached on the Flat Surface
Drag coefficient Boundary layer Numerical simulation Reynolds number
2016/3/28
The previous analytical solution for the drag coefficient (Cd) for a spherical particle attached on the flat surface, which
was derived by O’Neill (1968), is only valid in the creeping flow condition...
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...
