Over 1000 measured convective heat-transfer coefficients for normal cylinders in subsonic slip flow have been correlated by using Nusselt number as a function of Reynolds and Knudsen (or Mach) numbers. The experimental range corresponds to the following dimensionless groups: Mach number, M, 0.05 to 0.80; Reynolds number Re, 1 to 75; Knudsen number Kn, 0.009 to 0.077. Air temperatures between 0 and 280 degrees F and cylinder temperatures between 34 and 620 degrees F were used.
