In designing airplane wings, engineers need to take into account such factors as the speed and altitude at which the plane will fly, so that they can find a wing shape that balances lift and drag as well as possible. The American Heritage® Student Science Dictionary, Second Edition. ...
Direct numerical simulation (DNS) has become a powerful tool in studying fundamental phenomena of laminar-turbulent transition of high-speed boundary layer... X Zhong - 《Journal of Computational Physics》 被引量: 319发表: 1998年 Direct numerical simulation of hypersonic turbulent boundary layers. Pa...
However, focusing on the semi-circular ribs in a high-speed flow where the nozzle cross section is a square operating at Sonic and supersonic Mach numbers is not reported. The combination of experimental study and machine learning regressors’ ability to predict this highly sensitive data is ...
Using an electrostatic fluid simulation with cold ions and Boltzmann electrons, we have simulated the flow around spherical and cylindrical bodies, with and without a negative potential bias. Here, the flow speed vis assumed to be supersonic (faster than ion acoustic) and mesothermal (v<<v<<v...

Consequently, when the speed of the source, U, is less than sound velocity (a), the acoustic waves will inform the nearby fluid of the upcoming of the source. On the other hand, the information cannot transmit beyond the source and is limited to a cone of influence, called the Mach ...
which decreases its efficiency below the ideal linear speed-up. This overhead time depends on the scale of the parallel simulation, i.e. the number of parallel tasks or threads used. Since the higher order polynomials spend a longer time calculating the solution on a per degree of freedom ba...

The behavior of the jet and its interaction with the environment were also investigated. The new geometries proposed were analyzed in order to maximize the jet speed. 展开 关键词: Supersonic CFD pressure compressible gas potential core 会议名称: European Oxygen Steelmaking Conference ...
1 The term “high speed” is relative to the speed of sound in the fluid: shock waves always travel faster than the speed of sound. The strength of a shock wave is defined as its pressure ratio. A shock wave of infinitesimal strength is a sound wave; a strong shock wave has a ...
