Local Flow Boiling and Pressure Drop Measurements for R134a/Oil Mixtures Part 1: Evaporating in a Microfin Tube

Intube flow boiling experiments for refrigerant R-134a mixed with a lubricating oil are reported. The tests were run at a nominal inlet pressure of 3.4 bar over a wide range of vapor qualities at mass velocities of 100, 200 and 300 kg/m2s (73500, 147000 an ...

Online Measurement of Oil Concentrations of R134a–Oil Mixtures with a Density Flowmeter

John Richard Thome, Daniel Favrat

A very high accuracy, straight vibrating tube type of density flow meter has been used online to measure oil concentraiton of flowing R-134a/oil mixtures. The calibrations covered oil concentrations from 0-6 wt.% oil over the temperature range from -9.4 to ...
