Blowoff velocities and recirculation-zone lengths of propane-air flames stabilized by cylindrical flameholders were measured as a function of pressure (0.25 to 0.8 atm), cylinder diameter (3/8 to 1.0 inch), fuel-air ratio, and tunnel geometry (3 by 3 and 1 by 3 in.) for Reynolds numbers ranging from 0.64 x 10 to the 4 to 17.3 x 10 to the 4.
