Dear Professor Ungerechts,

Recently I have read the study of Schnitzler et al. "Adaptability in Swimming Pattern: How Propulsive Action Is Modified as a Function of Speed and Skill", doi: 10.3389/fspor.2021.618990, dated 2021.

Please see also a paper by Santos et al. Propulsive Forces in Human Competitive Swimming: A Systematic Review on Direct Assessment Methods: Propulsive Forces in Competitive Swimming., doi: 10.1080/14763141.2021.1953574.

With best regards,

Grzegorz

Dear Sir,

I hope it is useful to you.

Sincerely,

Thanks for this advice. It's not what I'm looking for, but a welcome proof of the importance of rotating fluid masses (apparently referred to here as swirl). What are then vortex forms asks the layman with internals for transient processes.

Thanks for the suggestions. It's not what I'm looking for, because I'm talking about "review of propulsion theories in swimming".

I'm thinking of theories like "thrust by suction", "thrust by lift", "thrust by vortex", "thrust by annihilation" etc. And I'm sure to have read such a review article. But I couldn't take any notes.

I hope this documents is what you are finding.

Sincerely,

See in the propulsion by the blades of the oars. It is necessary beforehand to eliminate the theory by suction and to search in the theory by pressure difference for example actuator (thrust 1D) or (torque 2D).

ups. I forgot to limit the request to Theories concerning Human Swimming. Anyhow I appreciate answers regarding all aquatic space activities :)
