Exact calculation of convection thresholds in rotating binary liquid mixtures
The exact sine series method of Stein [Phys. Rev. A 43, 768 (1991)] has been extended to allow the calculation of critical Rayleigh numbers and wave numbers for both stationary and oscillatory convect...

The initial development of the free-surface flow due to a submerged two-dimensional source (or sink) is studied analytically. The source is turned on at time zero. The fluid depth is infinite. The nonlinear initial/boundary-value problem is solved to second order in a Taylor expansion in time. A critical sink strength is found, for the formation of a surface dip. Its Froude number is equal to 1/3. The leading gravity wave is considered in the context of classical Cauchy–Poisson problems.
