In a former post , “Early earth simple model”, I considered the toroidal poloidal decomposition of the velocity solenoidal field. Here below, in the embedded pdf file, I expose some conditions for such a decomposition to exist and how it can be determined. The conditions are about the smoothness of the velocity field and the… Continue reading Toroidal poloidal decomposition

In the “simple model pdf” embedded below to read and/or download it, we consider a simple possible model for the earth at an early stage in the history of its formation, in which the earth was a nearly homogeneous fluid sphere with convective motions generated by an uniform distribution of heat sources under the influence… Continue reading Early earth simple model

In “Hydrodynamic and Hydromagnetic stability” by S. Chandrasekhar we find the analytical solutions for the Kelvin-Helmholtz instability problem for a semi-infinite heterogeneous inviscid fluid in wich density is exponentially decreasing with the height and the streaming velocity is continuously variable as a function of height . In this question, the Whittaker function and also the… Continue reading Whittaker function zeros
