Hydrodynamics of dolphins, fish and pin-‎nipeds

Romanenko E., Pushkov S.

The critical analysis of dolphins, fish and pinnipeds hydrodynamics in word-wide scientific literature ‎for the last 70 years is presented. Biohydrodynamic researches in the former USSR and Russia are ‎compared to the researches in other countries (including the USA). A lot of attention was paid to the ‎investigation of thin structure of the dolphins and pinnipeds boundary layer in the former USSR and ‎Russia. This method is essential for understanding of the dolphins hydrodynamic. Experiments of this ‎kind haven’t been carried out in Western Countries and the USA so far. The mathematical transfor-‎mations and formulas to calculate the dolphins fluke model thrust and power coefficients and ‎efficiency are presented.‎
