Several reasons caused the mismatch between W8 and W27. The following steps can minimize the differences in your cases:
- Using constant temperature BC for both the gas phase and solid phase.
- Provide the actual Young’s modulus, e.g. 78e9
- use the same “flpc” in different cases.
LENS_RAD = MAX_RAD * (1.0D0 + FLPC) - Other hydrodynamics related parameters, such as interpolation and revision of restitution coefficient
Summary:
The model is accurate for convection-dominated cases and the errors in conduction-dominated cases are larger. Your previous setup leads to high ratios of conduction/convection.
