Sealed Gravitational Capillary Viscometry of Dimethyl Ether and Two Next-Generation Alternative Refrigerants

The viscosities of dimethyl ether (DME, C2H6O) and of the fluorinated propene isomers 2,3,3,3-tetrafluoroprop-1-ene (R1234yf, C3H2F4) and trans-1,3,3,3-tetrafluoropropene (R1234ze(E)) were measured in a combined temperature range from 242 K to 350 K at saturated liquid conditions. The instrument was a sealed gravitational capillary viscometer developed at NIST for volatile liquids. Calibration ...

New Chemical Alternative Refrigerants

Due to the increased public concern over the role that chlorofluorocarbons CCFCs) play in depleting stratospheric ozone, a landmark international agreement , the Montreal Protocol, was signed in 1987 which regulated the production and consum ption of CFCs. More recently, several nations, most notably Canada, the Federal Rep ublic of Germany, Norway, Sweden, and the United States, have planned o...

New, Natural and Alternative Refrigerants

It is good to be able to pass on the best wishes of the International Institute of Refrigeration (IIR) and to remind you that the IIR will be holding its Gustav Lorentzen Memorial Conference in Glasgow next year. I hope that the IIR conference will be as well supported and as valuable as this CIBSE/ASHRAE conference. You are warmly invited to attend the Gustav Lorentzen conference in Glasgow, w...

Gravitational-wave Antennas for the next Generation

The sensitivity of resonant-mass gravitational-wave antennas has now reached h ≤ 10−18, where h is the dimensionless metric perturbation caused by the wave. In order to observe gravitational wave events such as coalescing neutron star binaries and colliding black holes from as far as the Virgo cluster of galaxies, the detector sensitivity must be improved by three orders of magnitude. With such...
