Investigation of the influence of conductivity of two-component geometry in Ansys Transient Thermal PART 3

In this post, we compare the heat conduction dynamics of geometry from the previous postss in two directions: longitudinal and transverse. Of course, all boundary conditions, or more precisely, their value, remain unchanged. The only variable will be the modification of their position.

Transverse or Longitudinal - which conduction is more dynamic ?

As mentioned above, we are repositioning our BC's. You can see all the modifications in the picture below.

Of course, analogously to our boundary conditions, we change the plot (temperature) of our individual finite elements. You can see their location in the picture below.

After performing the analyzes, we get a completely different temperature distribution after 600 s compared to the analyzes from the previous post.

Also, the plotted temperature gradient in Excel is already clear and significant. You can see that the course of both curves is separate.

In the next step, we will compare our Diff A and Diff B temperature gradients as a function of time.

You can see on the graph prepared in Excel that the position of the boundary conditions (tested gradient) of the same geometry has a significant influence on the dynamics of conductivity. The longitudinal gradient for the same convection values is over 15 times greater than the transverse gradient.
