First case: Omega1= 0.125 rad/s ---> Ta= 5000
Radial velocity in a radial cross-section
Deficit of velocity between the results obtained and the theoretical data v(theta)=a*r + b/r
The tore rolls appear clearly in the drawn sections.
Second case: Omega1= 0.073 rad/s ---> Ta= 1712
Third case: Omega1= 0.178 rad/s ---> Ta= 10000
A few remarks about the vizualisations: The maximum velocity in the rolls increases with the Taylor number. And the size of a roll ( his diameter) is forced to be less than the difference of both cylinder radius.
Fourth case: Omega1 = 0.25 rad/s ---> Ta =20000
For such a value of the Taylor number, six rolls appear,
seeming to prove that the number of rolls follows the same law and consists
in the same phenomenon as the Rayleigh-Benard instability.
Fifth case: Omega1= 0.395 rad/s ---> Ta=50000
