Sample interview questions: What are the challenges associated with modeling multiphase flows with phase change?
Sample answer:
Challenges of Modeling Multiphase Flows with Phase Change
- Complex Phase Interactions: Capturing the interactions between different phases (e.g., liquid, gas, solid) and their transitions (e.g., boiling, condensation) requires advanced numerical methods and accurate constitutive relationships.
- Non-Equilibrium Effects: Multiphase flows often involve non-equilibrium states (e.g., metastable liquids, superheated vapors), which introduce additional complexities and require sophisticated models.
- Large Simulation Domains: Phase change phenomena often occur over large spatial and temporal scales, making it computationally demanding to resolve the entire process efficiently.
- Interfacial Tension and Capillary Effects: Accurately captur… Read full answer
