EXPERIMENTAL DATA ON CHF FOR FORCED CONVECTION WATER BOILING IN LONG HORIZONTAL CAPILLARY TUBES
摘要
We present experimental results on critical heat flux in forced convection boiling of water in a horizontal capillary tube with inner diameter D = 1 mm, for L/D ratio approximately equal to 250, 500, and 1000. Data are for: low mass fluxes, between 800 and 2700 kg/m2s; pressures between 1.9 and 7.2 MPa; and inlet conditions between saturation and strong subcooling. In all cases fluid exit quality is high and critical heat flux is reached through dryout. Results are compared with extrapolations of the Katto correlation.
