ANACONDA bulge wave WAVE POWER BULGING SNAKEJUST A RUBBER TUBE IN THE SEA . . . . . full of water, closed at both ends, anchored head to waves
In this picture the waves come from the left. The arrows show the oscillating flow of water inside the tube.
The velocity of the bulge wave in the tube and the waves in the sea is the same; then the wave energy is transferred gradually to the tube.
At the bow, the wave squeezes the tube and starts a bulge running. But as it runs the wave runs after it, squeezing more and more, so the bulge gets bigger and bigger. The bulge runs in front of the wave where the slope of the water (pressure gradient) is highest. In effect the bulge is surfing on the front of the wave.
