Model of a Krogh Unit (blood vessel and surrounding tissue) Interface of "UDRS" refrigeration software CFD-grid of a beef carcass


I have published more than 100 refereed papers on the following topics:

Heat and mass transfer: Mixed convection. Numerical heat transfer.
A long-time interest in the development of efficient finite difference and finite elements technique to solve the phase change problem. ( Abstract )

Food engineering: Refrigeration. Freezing and chilling. Thermal properties of foods.
The food industry is one of the largest employers of chemical engineers and users of process engineering equipment. Refrigeration processes, in particular, are big users of energy and need to be modelled accurately and optimised.
See also International Congress Of Refrigeration, Sydney 1999.

Environment: Natural replacements for ozone-depleting refrigerants
Hydrocarbons, ammonia and other natural substances are ideal replacements for ozone-depleting CFC refrigerants. They are cheap, plentiful, and environment- friendly. They do not cause ozone depletion or greenhouse warming. So why are they not used more widely? ( Abstract )
(See also Greenpeace's Ozone Action Homepage. )

Artificial intelligence: Applications of genetic algorithms in chemical engineering
Modern minimisation methods such as evolutionary optimisation and simulated annealing, in conjunction with faster computers, are getting better in handling uncertainties and errors, in finding global optima and in coping with large problems. They have wide potential applications in the processing industries. ( Abstract )
