摘要: Abstract Experimental saturated and subcooled-pool film-boiling heat-transfer data from horizontal cylinders in liquid nitrogen for wide ranges of surface superheat, subcooling system pressure showed little dependence on the diameter relatively large diameters. A correlation subcooled pool film boiling heat transfer with diameters was derived by slightly modifying a theoretical solution based laminar boundary layer theory to accord better experimental data. similar applicable local vertical plates similarly using existing Local coefficients at midpoint light water PWR-type active fuel rod pulsed reactor agreed within error values calculated ranging 10 80 K.
