Stated mathematically: = where is the circulation around a material contour ().

circulation theorem V. Bjerknes's circulation theorem: 1) With reference to an absolute coordinate system, the rate of change of the Kelvin's circulation theorem: The rate of change of the circulation dC / dt of a closed individual fluid curve is equal Höiland's circulation theorem: An

7 Poincaré–Bjerknes circulation theorem. A similar principle which conserves a quantity can be obtained for the rotating frame also, known as the Poincaré–Bjerknes theorem, named after Henri Poincaré and Vilhelm Bjerknes, who derived the invariant in 1893 and 1898. However, Bjerknes liked to go in his own direction, he had "the courage to do stupidities" (a famous saying by Bjerknes) and never liked to follow the mainstream. This time his courage was rewarded by his circulation theorems.

Two years later he discovered the circulation theorems that led him to a synthesis of hydrodynamics and thermodynamics applicable to large-

This is not incorporated into either Kelvins or Bjerknes circulation theorem. 7 circulation theorem of Bjerknes in Spanish translation and definition "circulation theorem of Bjerknes", English-Spanish Dictionary online By 1898, Bjerknes had combined personal mechanical research with a general analysis of the two primitive circulation theorems of absolute motion derived by British mathematician and physicist William Thomson Kelvin and German physicist Hermann Helmholtz.
