About this file
The file is an Excel spreadsheet detailing wavemaker capabilities for a Navy solicitation (N0018925Q0376) for a towing tank wave generation system. The document includes technical specifications and performance data for wave generation across multiple frequencies (0.2 to 2.0 Hz), showing the current measured capabilities of an existing wavemaker. The specifications indicate requirements for wave height generation ranging from 2 to 57 feet, with specific performance criteria including wave steepness (L/10) and minimum wave height requirements.
The technical data reveals the wavemaker's current performance capabilities at different frequencies, with wave heights varying from 2.5 inches at 0.2 Hz to 6 inches at 1.0 Hz. The document includes critical analysis notes questioning some of the specification criteria, particularly around minimum wave height requirements. The solicitation is issued by the Department of the Navy Naval Supply Systems Command, targeting a technical solution for precise wave generation in what appears to be a research or testing environment, likely for naval engineering or maritime research purposes.

| (hz) | (sec) | (in) | ii - "Wavemaker must create regular waves from 2ft to 57ft" which means .3 to 1.6 fz We are OK there. | ||||
| 1.54 | 0.65 | 1.5 | ii - Minimum wave height of L/150 for 1" whichever is greater" Dumb criteria - at 0.3 hz we'd be OK if we couldn't make a wave less then 4.5 inches? At 1.6 hz we want to be able to make a 2 inch wave but would be OK if we can't make anything smaller than an inch?? | ||||
| 1.25 | 0.8 | 3.3 | ii - The wavemaker shall be capable of generating regular waves with a steepness of λ/10 to a maximum height of 3 ft. This is consistant with plot 2 and our current capability except below 0.4 hz where we can't make it that high | ||||
