3D Simulation with Flow-Induced Rotation for Non-Deformable Tidal Turbines

نویسندگان

چکیده

The overall potential for recoverable tidal energy depends partly on the turbine technologies used. One of problematic points is minimum flow velocity required to set rotor into motion. novelty paper setup an innovative method model fluid–structure interactions turbines. first part this work aimed at validating numerical classical cases rotation (forced rotation), in particular, with help a mesh convergence study. Once was independent from mesh, results were tested against experimental data both vertical and horizontal show that good correspondence power drag coefficients observed. In wake, vortexes well captured. Then, fluid drive code implemented. correspond expected physical behavior. Both turbines rotated correct direction coherent acceleration. This study shows fundamental operating differences between axis turbine. lack experiments free speed limitation, digital brake could be implemented overcome difficulty.

Elastically deformable 3D organs for haptic surgical simulation.

This paper describes a technique for incorporating real-time elastically deformable 3D organs in haptic surgical simulators. Our system is a physically based particle model utilizing a mass-springs-damper connectivity with an implicit predictor to speed up calculations during each time step. The solution involves repeated application of Newton's 2ndd Law of motion: F = ma using an implicit solv...

Simulation of local scour caused by submerged horizontal jets with Flow-3D numerical model

One of the most concerning issues for researchers is to predict the shape and dimensions of the scour pit nearhydraulic structures such as the base of bridges, weirs, valves and stilling basins due to both financial and humanhazards induced by destruction of the structure. As the scour issue has its own complexity in relation to themultiplicity of effecting factors on it, in this study therefor...

Tidal Turbines’ Layout in a Stream with Asymmetry and Misalignment

Abstract: A refined assessment of tidal currents variability is a prerequisite for successful turbine deployment in the marine environment. However, the numerical evaluation of the tidal kinetic energy resource relies, most of the time, on integrated parameters, such as the averaged or maximum stream powers. Predictions from a high resolution three-dimensional model are exploited here to charac...

Deformable Density Matching for 3D Non-rigid Registration of Shapes

There exists a large body of literature on shape matching and registration in medical image analysis. However, most of the previous work is focused on matching particular sets of features--point-sets, lines, curves and surfaces. In this work, we forsake specific geometric shape representations and instead seek probabilistic representations--specifically Gaussian mixture models--of shapes. We ev...
