Research Article | Legal requirements for refrigerants necessitate a continuous development of these fluids, also focusing on mixtures. In this study, mean heat transfer coefficients were determined for the condensation of two novel zeotropic mixtures, hexamethyldisiloxane (MM)/octamethyltrisiloxane and ethanol/MM, gathered for filmwise condensation on a vertical tube. Several compositions were investigated to provide a comprehensive understanding of the mixture effects. Based on the results a novel superposition approach to predict mixture condensation was developed.
