Phase-Change Phenomena

​

Introduction

• Many engineering applications involve solid-liquid and liquid-gas phase-change:

  • Thermal energy storage and management​

  • Liquid and solid fuel combustion

• Complex physical processes that require special numerical methods 

 

Research Details

• Melting of a heavy hydrocarbon (eicosane)

• 2-D incompressible laminar flow

• Complex physics:

  • Moving boundary problem​

  • Natural convection in the melt

  • Heat transfer through a thin molten layer

  • Solid movement and interaction with the melt

• Innovative coupling between the immersed boundary and enthalpy methods

• Fully resolved simulation
