Has anyone studied throttled expansion in thermodynamics?

Has anyone studied throttled expansion in thermodynamics? Does the volume always increase after passing through a throttling expansion device? If not, then why is it called throttling expansion, rather than throttling compression or throttling effect? As I understand it, the volume must increase, but my colleague doesn’t think so. What do everyone think of this process? Could you give some advice?
Haven’t heard of that thing; maybe the pressure increases after throttling and that’s what causes expansion!
If it is a supercooled liquid that is throttled, and it remains in a supercooled state after throttling, then its volume changes almost none. In cases of throttling under other conditions, the volume should increase significantly, accompanied by a drop in temperature. For isenthalpic processes, you can take a look at the Joule-Thomson process.
The pressure has decreased, and the temperature has dropped (except for hydrogen and helium)
