It would therefore be desirable to provide a more efficient and optimized method, apparatus, and system for converting kinetic energy from a fluid flow. 3-5, an experiment was conducted in a laboratory, more specifically a wind tunnel, to provide evidence of the optimized operation of the foil members 20 situated in the fluid flow 30 to attain one or more optimization objectives.
When immersed in a fluid stream, in this case a wind tunnel was utilized in a laboratory, the foil member oscillates due to vortex shedding from the leading and trailing edges and, as FIG. In this mode, the same physical hardware may be installed in different sites with different flow speed and depth, and the software will adapt itself to the site for maximum power conversion. Any combination of one or more computer readable medium(s) may be utilized in the present invention.

Stochastic methods, like simulated annealing, have the advantage that the mathematics behind the method guarantees convergence to the global optimum starting from any initial condition. The cost of optimization is expressed in terms of the number of objective function evaluations, and this translates into the number of measurements required to find the optimum. The method is very easy to implement to optimize over a few variables, but the simplex size grows with the dimension of the number of variables and rapidly becomes infeasible because a large number of measurements are required to find the optimum. The effect of the tidal farm could be to cause the suspended material in the flow to sediment because of the reduced flow speed or to be resuspended because of the turbulence. Our estimate of the available tidal resource is based on the implicit assumption that turbines are the only mechanism for power conversion, because these estimates identify sites appropriate for installation of turbines.
In all cases these are well within the range of our measurement and control capabilities. Such an optimization not only means that a careful, time-consuming and expensive site survey needs to be carried out to identify potential site. It appears that in a small range of mean angle of attack the motion of the foil is able to extract positive value of energy from the flow.

The foil member 20 generates lift primarily as a result of its shape and angle of attack. As the computational and communication ability of the onboard controller grows, optimization of more variables describing virtual coupling between the devices can be used to link them and mimic a large-scale device. Inflamación de rodilla con dolor . The optimization variables may be interpreted as the linear and nonlinear coefficients of the spring stiffness, damping coefficient, inertia, and form a finite dimensional space to optimize from, but are not necessarily restricted to physically achievable values, as long as on average energy is extracted from the flow and not fed in by the control system. Note, that the motion of the fluid is not solved computationally but observed and measured experimentally. The simplex method decelerates prohibitively in convergence speed for optimization over a large number of variables, but gradient based algorithms are ideal for such situations if the gradient is known.

Since each site for tidal hydro-kinetic power conversion is unique, and the conditions at that site vary over tidal, lunar, an solar cycles, turbines designed for one location cannot be installed in another without expensive redesign or reconfiguration. Therefore, while there is shown and described herein certain specific structure embodying the invention, it will be manifest to those skilled in the art that various modifications and rearrangements of the parts may be made without departing from the spirit and scope of the underlying inventive concept and that the same is not limited to the particular forms herein shown and described except insofar as indicated by the scope of the appended claims. Generally, hydrokinetic energy in the United States is largely located near densely populated areas, and as a result, has yet to be significantly harnessed. In addition, the actuator system is configured to submerge the foil member near or on a bed of a body of water when inactive.

In one embodiment, the sensor system comprises one or more sensors on the foil member 20 and in the surrounding area to measure and monitor flow conditions. The feedback control loop system 28 configured for optimizing the operation of the foil members 20 for the local environment and flow conditions in real-time to attain one or more optimization objectives.
