An experimental investigation of dryout heat flux in a saturated porous medium with forced flow from below has been conducted. Freon-113, methanol, and water were used as test fluids. Particle sizes were 0.59-0.79 mm, 1.6 mm, 3.2 mm, and 4.8 mm. The dryout heat flux increases as the inlet mass flux increases, and asymptotically approaches the total evaporation energy of the inlet flow. The pressure drop across the bed changes rapidly near the dryout point due to the formation of a dry zone.
