... illustrate the character of abundant over cooling from a dense cooling array. Spatially averaged iso-energetic heat transfer coefficients at different contraction ratios Cr for blowing ratios BR of 2.0, 5.0, and 10.0, are presented in Figs. 16–18 , respectively. These data represent a streamwise hole...

...% 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...
