Heat transfer and critical heat fluxes in the boiling of aqueous solutions of polyethylene oxide at reduced pressures under natural-convection conditions

Experimental data are presented on heat transfer and critical heat fluxes in the boiling of aqueous solutions of polyethylene oxide of different concentrations under conditions of natural convection at atmospheric and reduced temperatures.Notation q heat flux - q_cr critical heat flux - q_cr.s critical heat flux during boiling under subheating conditions - T overheating of heating surface relative to-saturation temperature - T_S subheating of liquid core to the saturation temperature - heat-transfer coefficient - P pressure - , densities of the liquid and vapor - c_p isobaric specific heat of water - r heat of vaporization Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 47, No. 1, pp. 24–28, July, 1984.
