2. 70%fill, plunger velocity = 9.6 in/sec (24.4 cm/sec), acceleration = 3.0 in/sec/in

    A. 3-D Experiment

    B. 2-D simulation

2-D simulations are compared with 3-D experiments. This experiments were conducted at Dr. Brevick's lab. in industrial engineering department in 1993.
Wave patterns of these simulations agree with those of experiments.
