Abstract

Interfacial tension measurements of the (CO 2 + N 2 + H 2 O) and (N 2 + H 2 O) systems are reported at pressures of (2 to 40) MPa, and temperatures of (298.15 to 448.15) K. The pendant drop method was used in which it is necessary to know the density difference between the two phases. To permit calculation of this difference, the compositions of the coexisting phases were first computed from a combination of the Peng–Robinson equation of state (applied to the non-aqueous phase) and the NRTL model (applied to the aqueous phase). Densities of the non-aqueous phase were computed from the GERG-2008 equation of state, while those of the aqueous phase were calculated knowing the partial molar volumes of the solutes. The expanded uncertainties at 95% confidence are 0.05 K for temperature, 0.07 MPa for pressure, 0.019 γ for interfacial tension in the binary (N 2 + H 2 O) system; and 0.032 γ for interfacial tension in the ternary (CO 2 + N 2 + H 2 O) system. The interfacial tensions in both systems were found to decrease with both increasing pressure and increasing temperature. An empirical correlation has been developed for the interfacial tension of the (N 2 + H 2 O) system in the full range of conditions investigated, with an average absolute deviation of 0.20 mN · m −1 , and this is used to facilitate a comparison with literature values. Estimates of the interfacial tension for the (CO 2 + N 2 + H 2 O) ternary system, by means of empirical combining rules based on the coexisting phase compositions and the interfacial tensions of the binary sub-systems, (N 2 + H 2 O) and (CO 2 + H 2 O), were found to be somewhat inadequate at low temperatures, with an average absolute deviation of 1.9 mN · m −1 for all the conditions investigated. To enable this analysis, selected literature data for the interfacial tensions of the (CO 2 + H 2 O) binary system have been re-analysed, allowing for improved estimates of the density difference between the two phases. The revised result on eleven isotherms were fitted with empirical models that generally represent the data to within 1 mN · m −1 . [ABSTRACT FROM AUTHOR]

Abstract

A fibre optic sensor for monitoring high pressures, using an in-fibre grating, has been constructed. The method involves tracking the wavelength of peak reflection from an in-fibre grating as it is pressurised. Experimental trials, under the influence of hydraulic pressure, have been carried out and a wavelength shift of 0.22 nm at 70 MPa pressure was observed. The sensor should be an attractive choice for ultra-high pressure monitoring.

Abstract

Ion-exchange in neodymium doped glasses has been used to fabricate waveguides which were optically pumped to realise lasers. The application of these layers as light sources in glass substrates will enhance the functionality of integrated optic systems in glass, allowing integration of active and passive devices. To obtain practical light sources, the neodymium-doped waveguides must be laser diode pumped to provide compact laser systems. Since the power available from a single stripe laser diode is limited, it is necessary to design the waveguide so that its modal field pattern matches that of the laser diode, thereby minimising the pump power required from the laser diode for the waveguide laser to reach threshold. We report on the fabrication and characterisation of waveguide laser pumped with a laser diode. These lasers operated in a continuous wave at a wave length of 1059nm, and were single transverse mode at both the pump and lasing wavelengths. The variation of the waveguide laser thresholds with the waveguide dimensions reveals the existence of an optimum dimension which minimises the laser threshold. A laser threshold of 20mW from the pump source and an overall slope efficiency of 5% with respect to the laser diode output power was obtained.
