Research Projects

1. Mass Transfer and Process Dynamics

Means of increasing mass transfer rates, particularly in electrochemical reactors,
are being explored. Studies on combined heat and mass transfer are being used to
develop design correlations. Investigations into fluidized bed electrode systems, and
into modelling time-dependent surface roughness in corrosion processes in flow
systems are being pursued.

2. Thermodynamic and Transport Properties

The relationship between thermodynamic and transport coefficients in non-ideal
systems is being explored. Calculations are proceeding on correlations for
diffusivity and activity coefficient data for non-ideal liquid systems.

3. Radioactive Waste Management

Reviews of scientific and technical issues, trends and operations regarding
disposal of high level radioactive waste are being made. Performance assessment
of disposal systems, and related environmental assessment approaches are
being evaluated.
