3. Modeling A#
3.1. Characteristics of modeling#
AXIS (TRIA6)
Boundary conditions:
Side \(\mathrm{AB}\): |
\(\varphi =500.W/{m}^{2}\) |
Side \(\mathrm{CD}\): |
\(\varphi =-500.W/{m}^{2}\) |
Side \(\mathrm{DA}\): |
\(h=377.W/{m}^{2}°C\) \({T}_{i}^{e}=130.+12.5z\) |
Side \(\mathrm{BC}\): |
\(h=339.3W/{m}^{2}°C\) \({T}_{e}^{e}=20.+12.5z\) |
Die-cutting:
49 items next \(y\) |
5 items next \(x\) |
3.2. Characteristics of the mesh#
Number of knots: |
1089 |
Number of meshes and types: |
490 TRIA6 (and 108 SEG3) |
3.3. notes#
Volume heat \(\rho {C}_{P}\) is not a step in this test, but must be declared for*Code_Aster*. We take \(\rho {C}_{P}=1.0J/{m}^{\mathrm{3 }}°C\).
Boundary condition \(\varphi =0\) is implicit on free edges.
3.4. Tested values#
The values tested are the temperatures and the flow densities calculated with option FLUX_NOEU.
