... of 20 deg and 30 deg, and contraction ratios Cr of 1 and 4 Fig. 27 Variations of spatially averaged heat transfer coefficients for blowing ratio BR of 5.0, hole spacings X / D  = 6 and Y / D  = 5, streamwise hole inclination angles of 20 deg and 30 deg, and contraction ratios Cr of 1 and 4...

...% of the critical pressure. Local heat transfer coefficients were measured for the mass flux range 200 < G < 800 kg ∕ m 2 ‐ s in small quality increments over the entire vapor-liquid region. Heat transfer coefficients increased with quality and mass flux, while the effect of reduced pressure was not very...
