Model Description

Initial temperature and flow rate is applied for the fluid domain. Temperatures and HTC in the cylinders (convection is applied on the structure domain) that can result from a combustion analysis.
FE Model
Element Types
The linear material properties are:
Young’s Modulus
21500 MPA
Poisson Ratio


Review the temperature contour on the structure and fluid domain, as shown in Figure 2.
