Analysis of heat exchange processes during ice drilling-melting by steam condenser

Abstract

Development of a high-performance thermodrill for high-speed sinking of "dry" wells with coring in snow and firn and ice deposits, based on the use of water vapor as an intermediate coolant on the principle of "open" steam tube, causes the necessity to find an analytical expression of the complex heat exchange between condensing steam and the ice face taking into account the shielding effect of the condensate film with thickness e inside the hollow annular condenser and the layer of melt water with thickness S, continuously formed under its working face during the drilling-melting process...
