Rotational Acceleration OF 1.7.1
i'm trying to solve a very complicate case, but i'm having great difficulties and i need the help of some expert.
I would like to evaluate the movement of a liquid contained in a tank, which is subjected to high linear acceleration and rotation velocity varying with the time. No analitical expression can be used, since the values (both g and omega) are taken from a txt file.
I've already used the interFoam solver (VOF) and modified it in order to get linear acceleration values (g) from the txt file. Since it is uniform for all the domain, these values are constant in space.
Now i need to do the same thing with the rotational velocity, in order to take in account the centrifugal, tangential and coriolis contribution. But i don't know how to implement a time varying rotational velocity, since it is uniform in space, but must be calculated for every cell.
Please, could someone help me? i'm desperate....
Hi , I'm trying to simulate a rotating CD with constant rotational acceleration , please let me know if you know how to do this
