SUMMARY:Hydrodynamic Lift Generation by Anguilliform Swimmers
DESCRIPTION:Lecturer:Alexander Rashkovsky\n Faculty:Department of Aerospace
  Engineering\n Institute:Technion – Israel Institute of Technology\n Loc

 bstract: \n Details: \n Sea snakes are air-breathing aquatic animals. They
  have lungs. When diving\, the volume of their lungs changes with depth\, 
 making them non-neutrally buoyant at least for a part of the dive. Gravity
 -buoyancy imbalance has to be compensated by hydrodynamic means. Moreover\
 , the center of buoyancy (xb) and the center of mass (xcm) may not coincid
 e\, and in this case the resulting couple has to be compensated by hydrody
 namic means as well.\n\nSimilar to many other elongated swimmers\, sea sna
 kes propel themselves by lateral deformation waves propagating along their
  bodies (nose to tail) faster than they swim. As opposed to other elongate
 d swimmers\, sea snakes also twist their tails in coordination with the la
 teral wave. This study attempts to quantify the hydrodynamic lift and coup
 le this type of propulsion can generate\, utilizing the framework of elong
 ated body theory originally developed by J. Lighthill.\n\nThe quantitative
  results are validated through the existing data of buoyancy states sea sn
 akes can swim at\, which appear to fit. The values of hydrodynamic couple 
 cannot be validated due to absence of relevant data\, however they appear 
 to be too small. Additional methods of dealing with excessive pitching mom
 ent are proposed.\n\n.\n\n.
