Jan 1, 2015 at 9:16 | comment | added | Isopycnal Oscillation | @stali i was interested because you mentioned instabilities. Which you expanded on in the comment - thanks. I have studied and simulated Rayleigh-Taylor instabilities in Boussinesq fluids, and it is interesting to see the same phenomena at those scales and with markedly different materials. | |
Dec 24, 2014 at 15:22 | comment | added | stali | @IsopycnalOscillation It is relevant though the reasons are subtle. See plate tectonics depends on mantle convection which depends on the viscosity of mantle rocks and onset of Rayleigh-Taylor instabilities. Water can alter both viscosity of olivine as well lower its melting point which in turn will have an effect on the onset of convection as well as its evolution. Now how drastic this effect is unknown. The only insight we have is from numerical simulations. It is my area :). | |
