“…It is clear that whereas the lift coefficient matches well with CFD results of [1] as well as the present work, the drag coefficient shows significant differences with both CFD results of [1] as well as the present work. However, the CFD of [1] always over-predicted the drag by a large margin. On the other hand CFD of the present work mostly underpredicts drag but its match with experiment is reasonably good and is much superior to the CFD of [1].…”

“…In this paper, experimental lift and drag characteristics of a well studied glider called 'ALEX' have been validated against the results obtained from computational fluid dynamics (CFD) [1]. This approach is then used for CFD analysis of a laboratory glider under development for Reynolds numbers varying from 10 5 to 10 6 .…”

Underwater glider moves vertically by change in buoyancy and moves horizontally due to wings. In this paper, we validate the experimental lift and drag characteristics of a glider from the literature using Computational Fluid Dynamics (CFD) approach. This approach is then used for the assessment of the steady state characteristics of a glider under development. Flow behavior and lift and drag force distribution at different angles of attack are studied for Reynolds numbers varying from 10 5 to 10 6 . The state variables of the glider are the velocity, gliding angle and angle of attack which are simulated by making use of the hydrodynamic drag and lift coefficients obtained from CFD. The effect of net change in buoyancy is examined in terms of the gliding angle, glider velocity, angle of attack and glider saw-tooth trajectory.

“…The hydrodynamic characteristic of a submarine launched underwater gliders was presented in Rodgers and Wharington (2010), and the glider shape was optimized to obtain a higher lift to drag ratio over a large range of attack angle. The effect of using actuated wings on a glider to enhance maneuverability were verified by experiments in a tank in Arima et al (2008Arima et al ( , 2009. This paper establishes a thorough approach characterizing the spiraling motion of underwater gliders: including the use of modeling, analysis, and experiments.…”

The purpose of this research is to develop underwater observatory systems for monitoring ocean ecosystem. It is very important to protect the global ecosystem and to preserve biodiversity in the ocean. Recently, various kinds of underwater vehicles were actively involved in ocean research, i.e.; seabed resources exploration, ocean environment monitoring. Underwater glider 'SOARER', deep-sea video camera system, the Oceanic Radio-controlled Camera Approacher 'ORCA 2 ' and an acoustic observatory system were developed for monitoring ocean ecosystem. SOARER has an ocean environmental sensors for monitoring depth, temperature, conductivity, salinity, DO, chlorophyll-a and turbidity. Ecology of marine organism living in a deep sea and marine mammals at sea surface can be recorded by using these devices effectively.Index Terms-Ocean-ecosystem monitoring, underwater glider, oceanic radio-controlled camera approacher, underwater observatory system
