xvelocity profile x=0.015


These comparison on xvelocity for x=0.005 and x=0.01 show us that the absolute value of the xvelocity is the same in the two cases. However, one can notice that the two curve are opposite, refered to the x=0 axe. This is due to the contrary rotative direction of the rolls, phenomenon explained in the previous part.


Temperature x=0.01


These results show us two things:
 on the one hand, the x=0.005 profiles show us that
the temperature is the same for the steady and the unsteady simulation.
This tend to confirm the results given by the x velocity profile:
results given by the steady and the unsteady simulations are the same
 on the other hand,, we can see that the evolution of
temperature on x=0.01 axe is different. This is due to the contrary rotative
direction of the rolls


Dynamic pressure x=0.01


These tests have been done only to confirm the fact that steady and unsteady simulations give the same results. At the contrary of the temperature,
Temperature x=0.005 and x=0.015


Dynamic pressure x=0.005 and x=0.015


The goal of these graphics is to see if the axe x=0.01, which is a symmetric axe for the geometrie of our domain, is a symmetric axe for the dynamic pressure and temperature fields. One can see that the temperature and pressure fields are identical on x=0.005 and x=0.01 axes for the steady simulation. For the unsteady simulation, there are little differences, but there negligeable. So this results tend to show that in the two cases (steady and unsteady), the symmetric axe for the geometrie is a symmetric axe for the fields which caracterize the flow.
