circulation theorem of bjerknes — Svenska översättning

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. 2.2, The Circulation Theorems Well before Vilhelm Bjerknes, Leonard Euler had pio- neered the science hydrodynamics. 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. at that time unknown to Bjerknes, who developed one of Bjerknes’ two circulation theorems with out comprehending its far-reaching implications.

Vilhelm Bjerknes introduced an extension of Kelvin's ideas on circulation into geophysics. In this essay a historical perspective will be given on what has become known as the “Bjerknes circulation theorem.” Bjerknes wrote several papers on this topic, the first being in 1898. circulation theorem, obtained independently by Kelvin and Helmholz, on the conservation of circulation (vorticity) in barotropic fluids (Bjerknes 1898; 1900; 1902; Thorpe et al. 2002). With this work he also united the disciplines of hydrodynamics and thermodynamics, which until then had developed independently and along separate lines.

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. The Bjerknes circulation theorem is a relatively simple model that begins with the presence of a cross‐shore mesoscale PGF and reproduces the SBC from an initially stationary atmosphere.

This is just the line integral of v over γ, which we can rewrite for any surface m which has γboundary. Kelvin’s Circulation Theorem It follows that in a homogeneous and frictionless fluid, circulation is conserved.
