A multiphase system is one characterized by the simultaneous presence of several phases, the two-phase system being the simplest case. The analysis of multiphase systems can include consideration of multiphase flow and multiphase heat and mass transfer. Based on the phases that are involved in the system, phase change problems can be classified as: (1) solid-liquid phase change (melting and solidification), (2) solid-vapor phase change (sublimation and deposition), and (3) liquid-vapor phase change (boiling/evaporation and condensation).
- Basics, integral formulation, differential formulation, claisfications of PDE and boundary conditions, boundary conditions at interfaces, and averaging formulation.
- Surface tension, contact angle, wettability, disjoinig pressure, interfacial thermal resistance, and instability.
- Classification, boundary conditions at interface, exact solution,and numerical solution, effect of natural cvonvection.
- Basics, dropwise condensation, vertical plate, cylinder and sphere, nongravitational condensate removal, and film condensation in porous media.
- Pool boiling regimes, nucleate boiling, critical heat flux (CHF), transition boiling, minimum heat flux, film boiling, and boiling in porous media.
