Effects of counterflow jet on the performance of a generic rocket
Autor: John Baker, Semih M. Ölçmen, Gary C. Cheng, Richard Branam
Publikováno v: Acta Astronautica. 182:219-229
Effects of a jet emanating from the nose of a generic rocket in the opposite direction of the incoming freestream have been studied to determine the effects of the jet in reducing the drag and the heat loads on the rocket. The effects are comparative

Effect of Counterflowing Jet on Supersonic Slender-Body Configurations: A Numerical Study
Autor: Gary C. Cheng, Balaji Shankar Venkatachari, Chau-Lyan Chang
Publikováno v: Journal of Spacecraft and Rockets. 57:1204-1221
Previous studies have demonstrated that the use of counterflowing supersonic jets operating in the long penetration mode (LPM), directed from the nose of blunt bodies against a supersonic/hypersoni...

Computational investigation of axi-symmetric plume induced flow separation
Autor: Yitong Gao, John Baker, Semih M. Ölçmen, Richard Branam, Gary C. Cheng
Publikováno v: Acta Astronautica. 160:106-115
The flow over a rocket may result in plume induced flow separation (PIFS) depending on flight conditions and nozzle-to-ambient pressure ratios. In the current study, the flow structure over a generic rocket model has been investigated to determine th

Minimum drag and heating 0.3-caliber projectile nose geometry
Autor: Gary C. Cheng, Richard Branam, Semih M. Ölçmen, Stanley E. Jones
Publikováno v: Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science. 233:1990-2000
Understanding the performance of penetrators and aerodynamic bodies of revolution (missiles, rockets, aircraft noses, etc.) requires a close look at the drag and the heat transfer characteristics at a wide range of supersonic flight conditions. This

Assessment of surgical effects on patients with obstructive sleep apnea syndrome using computational fluid dynamics simulations
Autor: Yasushi Ito, Peter D. Waite, Somsak Sittitavornwong, Roy P. Koomullil, Alan M. Shih, Gary C. Cheng
Publikováno v: Mathematics and Computers in Simulation. 106:44-59
Obstructive sleep apnea syndrome is one of the most common sleep disorders. To treat patients with this health problem, it is important to detect the severity of this syndrome and occlusion sites in each patient. The goal of this study is to test the
