Resum
The onset of convection in fluids confined in a vertical rotating cylindrical annulus with radial gravity and heated from the inside is analyzed. Solutions to the eigenvalue problem are found numerically for flat lids and either no-slip or stress-free boundary conditions on these surfaces. Except in special cases occurring with the latter boundary conditions all critical modes precess in the rotating frame. The critical Rayleigh number and the corresponding precession frequency are computed for ...
