PhD,
in Physics, ”Thermal Conductivity of Simple Molecules Between 100 and
450 K and up to 10 MPa”, Instituto Superior Técnico, supervision of
Prof. C. A. Nieto de Castro, January,
1988. Liquid and gaseous argon as well as liquid methane were studied in
this work, as a function of temperature and pressure. A cryostat, using
liquid nitrogen, was designed and constructed to operate in this
temperature range and capable to guarantee a thermal stability of 0.01 K
during about 20 minutes. All the automatic instrument was improved and new
pressure and vacuum systems were developed. q

q A new Laser Flash Instrument, for the measurement of the thermal conductivity of rocks up to 2200 ºC, was recently acquired (Anter Corporation, model FL5000), financed by PRAXIS XXI. This project is being developed in the Department of Physics under my responsibility. q
A
feasibility study was made after the PhD (as part of an EC project); the
objective of this study was the definition of a standard method for the
measurement of the thermal conductivity of high temperature melts between
300 and 1500º C. This work took 3 years, and 2 reports were presented: q
The
first one concerning a detailed analysis of the existing methods for the
measurement of the thermal conductivity that can be used, with or without
modifications, to the study of liquids. q
The
second one involved the proposal
of a new standard method for the measurement of the thermal conductivity
of high temperature melts. q A computer simulation, using the finite difference method to evaluate the solution of the integro-differential heat conduction equation, was made. In this case the analytical solution was not possible to obtain. This work was made in collaboration with Prof. W.A. Wakeham (Imperial College, London). q
Study
of Environmentaly Acceptable Refrigerants: q
Measurement
of the thermal conductivity of new environmentally acceptable refrigerants
for the protection of the ozone layer (co-orientation of the PhD thesis of
Anélia N. Gurova, 1996). Several alternative refrigerants, such as
HCFC123, HCFC141b, HCFC142b, HFC134a and HFC152a,
were studied between –90ºC and +30ºC and up to 20 MPa.
Correlations of the data obtained and comparison with the existing data in
the literature was performed. It was also applied the hard sphere model in
order to obtain a general correlation with a physical basis. q
Dielectric
constant of the same compounds (co-orientation of the PhD thesis of Maria
G. Barão, 1996). Several alternative refrigerants, such as HCFC123,
HCFC141b, HCFC142b, HFC134a and HFC152a,
were studied between –90ºC and +30ºC and up to 20 MPa.
Correlations of the data obtained and comparison with the existing data in
the literature was performed. The Kirkwood theory and the Vedam theory
were applied to data obtained. Subsequent work is in progress; several
refrigerants have been studied (HFC32, HCF125 and HFC143a) and also some
mixtures of these refrigerants (R404A, R410C, R407C and R507), in the same
thermodynamic region. |
