R134a, commonly used for automotive air conditioning, will be phased out due to its high global warming potential, while R1234yf/R290 and R1234yf/R600a were considered as two potential alternatives owing to their excellent environmental characteristics. In this work, the thermophysical properties and cycle performances of the above refrigerants wer...

AbstractExperimental analysis of viscosity can be a straightforward and inexpensive analysis for few samples. However, in industrial processes that have high demands of properties measurements, the determination of viscosity and other properties involves time-consuming with sampling, analysis, and availability of results. Also in refineries, the sa...

A database of the thermal conductivity of fused quartz was developed using the KD2 Pro thermal properties analyzer. The database contains the thermal conductivity data of fused quartz with changes in soil porosity and temperatures ranging from 5 ℃ to 45 ℃. The measured data show that the thermal conductivity increases with increasing temperature un...

This study investigates the determining parameters of thermal comfort of office in an arid hot-arid environment of Bechar, located in the northwestern region of Algeria, in which the vertical walls of the room and the roof are subjected to solar irradiations and the floor is considered to be adiabatic. The solar flux is calculated by the ASHRAE (Am...

The laser thermal lens spectroscopy (TLS) was used to measure the thermo-optical parameters of alcohols(1)–trichloromethane(2) binary mixtures with high accuracy. Using this spectroscopic method, the thermal lens characteristic time (tc), thermal diffusivity (Dth), thermal conductivity (k), thermo-optic coefficient (dn/dT), and the refractive index...

We present a new wide-ranging correlation for the viscosity of ethane-1,2-diol (ethylene glycol) based on critically evaluated experimental data. The correlation is designed to be used with an existing equation of state, and it is valid from the triple point to 465 K, at pressures up to 100 MPa. The estimated uncertainty is 4.9 % (at the 95 % confi...
