Results from a GOTHIC simulation of a test performed in the Marviken experimental facility in 1976. The test includes venting of air, then steam, through vertical vent pipes submerged in a pool of water. The vented air forms large bubbles in the pool and lifts the pool surface. The steam venting that follows results in smaller bubbles that condense in the pool. This simulation validates GOTHIC's ability to predict vent clearing, pool swell and condensation heat and mass transfer in steam bubbles.

Results from a GOTHIC simulation of solid particles transported by water, including the effect of settling, bed load, and resuspension. Liquid laden with 2% particles is horizontally injected in the upper left at a velocity of 2 ft/s for 0-800 seconds and then vertical injection of liquid with increasing velocity over time starts at 800 seconds. A vent is located in the upper right. The animation shows the particle volume fractions and velocity vectors over time.
