Thermal Relief - two phase fluid
Thermal Relief - two phase fluid
(OP)
Thermal relief is considered for liquid filled systems. What if the fluid contains a few percent gas? Does the presence of the gas cause the fluid to no longer be considered a liquid, and therefore discount the need to provide thermal relief protection. I am making the assumption that the density of the gas phase increases faster than the density of the liquid phase as temperature increases.

The issue here as I see it is how reliable your "few percent" is. That only you can answer, but if the gas can be swept out or absorbed into the liquid under various conditions, then no it doesn't allow you to avoid thermal relief protection.
It's all about the worst case because thermal expansion pressures unrelieved can be very high.
