Determination of viscosity in ethanol and HFA 134a mixtures
conference contribution
posted on 2018-06-18, 13:12 authored by R. Johnson, D.I. Lewis, Paul M. Young, Hendrik Versteeg, Graham HargraveGraham HargraveKnowledge of formulation liquid properties is beneficial when modelling internal transient flows of pMDI HFA 134a and ethanol binary mixtures during atomization1, 2. Non-linear expressions are available that correlate saturated vapor pressure, density and surface tension to HFA 134a-ethanol composition3, 4 2. In this study, experimentally determined dynamic viscosity is presented for ethanol-HFA 134a mixtures at 20.4 ± 1.2°C.
