Experimental and Computational Fluid Dynamic Study of Water Flow and Submerged Depth Effects on a Tidal Turbine Performance

This study involves an experimental and numerical analysis of the Hunter turbine, a vertical axis turbine utilized for tidal energy. A laboratory model featuring aspect ratio 1.2, was designed tested. Numerical equations, including Reynolds-averaged Navier–Stokes (RANS) constant, were analyzed through computational fluid dynamics (CFD) software using k-ω turbulence to forecast performance other related flow specifications, such as pressure lines, stream velocity, pressure. simulation conducted on surface blade, results obtained accordingly. The data verify results, difference between two reasonably acceptable. studied in six different coefficients four positions. indicated that power coefficient increased submerged depth from water-free increased, after specific depth, output remained constant. It also observed minimum maximum three times diameter drum (3D).
