For the computation of the CFD efficiency values, the results
from the simulations with the barrier tilted at 10°
were used. Given that the median current speed at the
selected location (31°N – 142°W) is 0.13 m/s, the data obtained
from the simulations with 0.10 m/s and 0.15 m/s
was used to obtain (and interpolate) the corresponding
capture efficiencies.
Sea water physical propert ies
The physical properties of the fluid considered (sea water)
(density, viscosity and far field turbulent quantities)
are given in Table 3.1, which corresponds to 10% velocity
fluctuations for k and to a turbulent length of H/10 for ε.
The input parameters used in this 2D CFD study are summarized
in the Table 3.4.
