31. Sealed Gravitational Capillary Viscometry of Dimethyl Ether and Two Next-Generation Refrigerants
Journal of Research (NIST JRES)
Dylan S. Cousins, Arno R Laesecke
The viscosity 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)) was
measured in a combined temperature range from 242 K to 350 K ...
32. The Effect of Piping Heat Losses on the Efficiency of Solar Thermal Water Heating in a Net-Zero Energy Home
Tania Ullah, William M Healy
This study evaluates the thermal performance of an dual-tank domestic hot water (DHW) system designed for a net-zero home at the National Institute of Standards and Technology, Gaithersburg Maryland campus. Hot water demand for a virtual family of fo ...
33. WATER TRANSPORT ACROSS A POLYMER ELECTROLYTE MEMBRANE UNDER THERMAL GRADIENTS
David L Jacobson, Richard Fu, Takeshi Shiomi, Ugur Pasaogullari, Joshua Preston, Shinichi Miyazaki, Yuichiro Tabuchi, Daniel S Hussey
A fundamental experimental and numerical study of the water transport across a perfluorosulfonic
acid (PFSA) membrane under a temperature gradient is presented. The water transport phenomenon was
experimentally investigated through water flux mea ...
