Sinopsis

The effects of g-jitter on three fluids enclosed in a container are numerically investigated. The g level used in the study is composed of a steady component and a time varying sinusoidal component (with frequency 10−2, 10−1 or 1 hz.). Impulse type forcing is also investigated. The results show that complex flow patterns can arise that significantly modify the heat transfer characteristics of the system. The effects are more pronounced at the lowest frequency of 10−2 hz. than at the higher frequencies. Impulse induced effects are found to take a fairly long time to decay to steady state conditions. Detailed velocity, temperature, average Nusselt number and temperature sensitivity information is presented for many of the cases that were investigated.
