A friction factor correlation based on pressure drop measurements at burnout in an annular channel is presented. From Reynolds analogy and this correlation, critical heat fluxes were predicted within ±10 percent of the values measured with ideal geometry (no ribs), stainless steel heaters, and H2O coolant flowing vertically downward at a velocity of 15 to 45 ft/sec and subcoolings greater than 25 deg C. Tubular critical heat fluxes are predicted within ±20 percent using the friction factor correlation and Reynolds analogy. A short theoretical discussion is presented.
