Pressure fluctuations in the base region of a typical missile configuration at freestream Mach number 0.7 are examined experimentally presence and absence cavity. The objective was to characterize pressure explain influence cavities on their behavior. Experiments include unsteady measurements six azimuthal locations. Substantial variation characteristics is noticed along direction due asymmetry model. seen enhance reduce root mean square fluctuations. Higher-order moments show diminishing...
The long endurance, energy efficiency and nature of locomotion have proved underwater glider (UG) to be the most suitable choice for long-term ocean environmental monitoring detection marine resources. Being buoyancy driven slow speed vehicle, external disturbance such as waves significantly affect operational autonomy stability UG along designed glide path. assessment these disturbances on is important design better control systems vehicle designs. Accurate wave predictions methods are...
The effect of drift angle on a ship is investigated through towing tank tests and using Computational Fluid Dynamics (CFD). Resistance wave elevations obtained from the computational study are validated with experimental results. Detailed free surface, mean velocity pressure flow fields hull surface for Fn ranging 0.16 to 0.22 β = 0, 5 10°. lateral force, yaw moment asymmetric characteristics brought out in study.
