The contribution of the viscous dispersion of kinetic energy to thermal energy has been significantly overestimated in three recent publications. The internal kinetic energy of the macro-scale average current is assigned as exothermic to heat energy. It is estimated to lead to an increase in temperature, which contributes significantly to the melting of ice on Greenland.
ONE recent news release published the findings of the study and a video of a lake melting into glacier ice in the news and also at YouTube here.
Another estimate, where the viscous dissipation is determined at the microscale of the flow, is calculated in these notes. This estimate, and the associated temperature increase in the runoff, is significantly less than the macroscale-based estimate. PDF file with my analysis here [BSLdissip02]
Comments, especially corrections for mistakes, would be appreciated.
