| Abstract: | Underwater glider is the new generation of autonomous underwater glider
which has been used for ocean observation and wide range of marine environment
monitoring. It glides through seawater horizontally and vertically by carried
additional wings. This paper presents the investigation of hydrodynamic
characteristics of the shallow underwater glider by using Computational fluid dynamics
(CFD) code, FLUENT 6.3.26. A 3-dimensional Spalart-Allmaras turbulence model is
used to estimate hydrodynamic performance of the glider. The effect of angle of
attack (varied from -8º to +8º) at various Reynolds
numbers and the flow behavior of underwater glider at different flow conditions
are studied. The characteristics such as lift and drag forces, lift and drag
coefficients and pressure distribution over fixed wings are evaluated in a flow
field with Reynolds number ranging from 105 to 106. Lift
and drag coefficients are observed to rise as function of angle of attack. Wake
formation occurs at the tail and the junction of main wing and fuselage body,
and the nose is exerted to highest pressure force compared with the other
parts. |
