Variation in the flow speeds adjacent to the eel's body over one tail-beat cycle. Variation in the flow speeds adjacent to the eel's body over one tail-beat cycle. The values at a particular position along the body can range from close to zero when the body segment is close to an inflection point of the midline to maximum values when the segment is in the low- or high-pressure zone. The maximum flow speeds, indicative of the transferred momentum, increase almost linearly from head to tail. ULRIKE K. MÜLLER et al.
