HERO WEC V1.0 2024 - WEC-Sim Detailed Simulation Runs and Summary Data

Data sets from simulation runs include 135 wave cases that were run based on the WEC-Sim model (https://mhkdr.openei.org/submissions/553). This model supersedes submission #485. The data represented in this submission is based on an updated WEC-Sim model using laboratory data to tune and refine the original WEC-Sim model for the V1.0 HERO WEC.

The 135 wave cases represent waves with the following wave height and wave period ranges:

- Significant Wave Height: 0.25 - 3.75m in 0.25m increments
- Wave Period: 5 - 13 sec in 1 sec increments

Each run was simulated using a Pierson-Moskowitz irregular wave spectrum with a 100 second ramp time and a total simulation time of 3,100 seconds and a simulation time-step of 0.005s. A reference table has been included to map each MCR case with each wave condition (HEROV1_2024_MCRruns.xlsx).

Summary data set includes a spreadsheet (MCR Matrices.xlsm) and image files (Matrices_pngfiles.zip) with matrices that are associated with data from simulation runs. All matrices cover the same significant wave height and wave periods from the simulation runs, in the same increments. The following matrices are included:

- Power Abs: The average absorbed power from the WEC (calculated from anchor reaction force and heave velocity)
- Power Hyd: The average hydraulic power output at pump (calculated from pump output flow and pressure)
- Power - Hyd ROi: The average hydraulic power measured at the RO system inlet (calculated from RO system pressure and flow (pre-accumulator))
- Flow - Pump out: The average flowrate measured at the pump outlet
- Flow - Perm: The average permeate (clean water) production
- Flow - RO (pre): The average flowrate measured at the inlet of the RO system before the accumulators
- Flow - RO (post): The average flowrate measured after the accumulator bank in the RO system
- Pressure - RO: The average pressure measured at the inlet of the RO system
