Rotating tank experimentation-Sloping Bottom run #2

11/05/10

    Running another experiment (on Thursday November  4, 2010) with 10 revolutions per 1 minute for the rotation of the tank. In this run the spin tank was

rotated anticlockwise. Further investigation is needed to measure the velocity of the water particle maybe utilizing PIV (particle image velocity) measurements.

In contrast with the first run some speculation why a beautiful three wave structure pattern emerged so rapidly was due to trial and error quick-fixes. The first quick-fix was to add sponges in the inner cylinder so that ice (almost zero degrees Celsius) could be concentrated in the upper layer of the tank which is not what we had in the first run so could possibly be a reason why we had such a beautiful structure pattern. The temperature gradient in this run was much less ergo  the fluid behavior came out the way it did shown in the video. 

The experiment took place with Dr Huei-Ping, PhD student Ashish Sharma and FURI (Fulton Undergraduate Research Initiative) funded student Michael Thompson.
