The study of transport processes is key to countless applications from multiphase flow in pipelines to boiling flows in concentrating solar power plants and combustion in engines. Understanding the fundamental phenomena of fluid mechanics, mass transfer and heat transfer associated with such systems informs their efficient design and operation, translating to tangible improvements in performance. In the Transport Processes Division, advanced experimental methods including state-of-the-art optical techniques are employed to gain insights into transport phenomena through detailed measurements with high spatial and temporal resolution.

The research activities conducted by the Transport Processes Division are:

  1. Multiphase/Interfacial flows
  2. Heat transfer
  3. Phase change
  4. Chemically-reacting flows
  5. Complex fluids, heat transfer enhancement and drag reduction
