摘要

Energy and work are calculated or estimated in several laboratory vessels and compared to estimates of energy/work at sea. Some measurements completed by PIV and anemometry are compared to these calculated values. The initial measurements and estimates indicate that the energy in several laboratory vessels is similar and that it may be equivalent to those encountered at sea under moderate wind and wave conditions. Two techniques have been initiated to measure energy. The measurement technique chosen to do this is Particle Image Velocimetry or PIV. In this method, seed particles - which could be oil droplets, are put into the fluid and the fluid is illuminated with a laser at one of 4 chosen wavelengths. The movement of a particle in a given cell is measured as a function of time. This can occur as fast as 30 Hz. Turbulent energy can be calculated at each point in the image frame. The other method used is the method of using hot wire anemometry. This method can yield data similar to PIV, however requires the intrusion of a probe into the area. The methods are compared in several laboratory vessels under several energy conditions. This year's work includes new measurements in several apparatuses.
