Design Method for Sailing Boats by CFD Performance Simulation

Numerical simulation of sailing boats: dynamics, FSI, and shape optimization

The numerical simulation of free-surface flows around sailing boats is a complex topic that addresses multiple mathematical tasks: the correct study of the flow field around a rigid hull, the numerical simulation of the hull dynamics, the deformation of the sails and appendages under transient external conditions like gusts of wind or wave patterns and, overall, the coupling among all these com...

Adaptive sampling with a fleet of autonomous sailing boats

Autonomous sailing boats are an attractive solution to perform measurements at sea thanks to their low energy consumption. A fleet of such vehicles can also be used for adaptive sampling of an environmental field. In previous work, artificial potential fields have been used successfully in a local and real-time planner to carry out the autonomous navigation of one sailing boat. In this paper, w...

Design and Performance of Ropes for Climbing and Sailing

Ropes are an important part of the equipment used by climbers, mountaineers and sailors. On first inspection, most modern polymer ropes appear similar, and it might be assumed that their designs, construction and properties are governed by the same requirements. In reality, the properties required of climbing ropes are dominated by the requirement that they effectively absorb and dissipate the ...

simulation and design of electronic processing circuit for restaurants e-procurement system

the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...
