要約

Combined investigation of the scale formation and heat transfer in boiling at high heat fluxes provides the possibility to obtain additional data on hydrodynamics of wall layer near the heating surface. A salt method makes it possible to estimate both the effective degree of fluid evaporation within the wall layer at high heat fluxes and the effective temperature of a liquid phase within the wall layer at moderate heat fluxes. This method demonstrates that heat transfer crisis in boiling is due to deterioration of mass transfer between the flow core and the wall layer in question.
