The modeling of many physical processes includes transport phenomena, such as mass and heat transfer. The corresponding governing equations are often either one-way coupled to a flow field via a convection term or, when the transported physical quantity also influences the flow, even two-way coupled. Our computational approaches for solving the (coupled) transport equations are based on multiscale and stabilized finite element methods.

Examples for transport phenomena are:

• general transport of any scalar physical quantity
• heat tranfer in solids and fluids
• mass transport in solids and fluids
  • nano-particle transport in the human lung
  • gas exchange processes in the human lung
  • chemical species transport in biofilms
• multi-ion transport in electrochemical systems
• level-set equation

Transport phenomena are currently addressed in several of our applications such as:

• Biofilms
• Chemically reacting flows
• Combustion
• Electrochemical power sources
• Electrodeposition of metals
• Electroforming of rocket combustion chambers
• Multiphase flows
• Respiratory system
• Thermo-(Fluid-)Structure Interaction
• Variable-density flows
