Thanks so much, Chet. In practice, the PCM will be in a container, but the container will always be cooled at roughly room temperature. We were thinking that assuming the surface is in contact with air would at least eliminate the container as a variable, plus make it simpler to confirm by...
A colleague and I want to model how a slab of PCM (wax) solidifies as it cools off. What I have noticed in my experiments is that temperature sensors on the top and bottom of the slab say it should be solid, as they read well below the melting point. But when I peek at the sample, the center...
