Aspen Physical Property System - Physical Property Models

3 Transport Property Models
This section describes the transport property models available in the Aspen
Physical Property System. The following table provides an overview of the
available models. This table lists the Aspen Physical Property System model
names, and their possible use in different phase types, for pure components
and mixtures.
Viscosity models
These models calculate MUL (pure) and/or MULMX (mixture) for the liquid
phase, and MUV (pure) and/or MUVMX (mixture) for the vapor phase, except
models marked with * calculate MUVLP (pure) and/or MUVMXLP (mixture) for
the vapor phase, and models marked with ** calculate MUVPC (pure) and
MUVMXPC (mixture).
