Background

Pat Jordan has continued research in supercritical fluid extraction, in applications of computational fluid dynamics to practical problems, wood technology and in heat transfer. He was Interim Director of the Wood Technology Research Centre for 12 months in 2001/2002. A sabbatical leave spent in the Computational Fluid Dynamics Centre, University of Leeds, in 1998-1999 has led to the introduction of CFD courses at undergraduate and Masters level at the University of Canterbury.

A particular interest in undergraduate teaching has been the development of spreadsheet-based methods of solving heat transfer calculations.

Research Interests

Wood technology
A lab scale panel press is in use for studying the hot pressing of medium density fibreboard panels. The pressing process is also being mathematically modelled.

Studies are in progress on the size of wood dust particles generated during sanding operations in wood turning to help assess the hazards faced in using a wood lathe.

Computational Fluid Dynamics
Applications modelled have included vapour-liquid separation in a falling film evaporator, flow through membrane systems, dispersal of chloramines in a swimming pool building, mixing in an mdf blowline, and heat transfer in an agitated vessel.

Supercritical Fluid Extraction
A lab-scale supercritical fluid extraction apparatus is in use for extraction of materials from plant sources. Earlier work studied the solubility and separation of triglycerides and other lipids, with analysis done either on-line or off-line by HPLC.

Heat Transfer
Experimental studies have been made on heat transfer coefficients within agitated vessels.

Research has been carried out in conjunction with NZ Dairy Research Institute on heat transfer in falling film evaporators.
