'water closed flow simulation' simulation project by afischer


#1

I created a new simulation project called 'water closed flow simulation':

Water flow from the tank of a water closet down. Kind of a fun project but with a very interesting analysis on the shear stresses on the inside walls dependent on the different designs, showing a much better performance for the design introducing a rotational flow.


More of my public projects can be found here.


#2

Flow simulation of a toilet flush

A focus was set on analyzing the wall shear stresses based on two different design for the inlets into the water closet. The analysis shows that the shear stress is much more equally distributed for the small inlets that introduce a rotational flow inside the wc.

Note that the simulation on the right diverged at the end of the simulation time and can not be taken into account for the last timesteps
