Present Research Interests:

Design and development of new methods and instruments for the measurement of thermophysical properties of fluids, in particular, density, viscosity and thermal conductivity (Five Doctorate Theses have been supervised in this area). The work is generally aimed at providing data with an accuracy fit for selected applications. In general the main purpose is to enable the development of better property prediction, estimation, and correlation methods, for the design and modelling of scientific and industrial equipment. A fundamental driving force of the work is the need for a better understanding of the relation between molecular interactions and the thermophysical properties of matter. As a result of these efforts novel instruments have been designed and built. In particular, it has been constructed an instrument to perform simultaneous measurements of the viscosity and the density of fluids, over wide ranges of temperature and pressure, which has been used for pure fluids and mixtures involving supercritical carbon dioxide. The most recent instrument is a vibrating wire viscometer that has shown to be able to measure viscosity from 0.5 mPa×s to about 265 mPa×s, with an estimated overall uncertainty of ±1 %, after direct calibration with the viscosity primary standard (water at 20 ºC).

Some of the work presently being carried out involves: (i)  the study of industrial reference liquids for moderately high viscosity (50 to 200 mPa×s); (ii) the development of an instrument to measure viscosity in industrial environment; and (iii) the study of ionic liquids.
