Recent investigation has increased attention in using ,supercritical, carbon dioxide (s-,CO 2,) as a potential HTF in PTC applications . Its main advantage is thermal enhancement when compared with subcritical ,CO 2, as it behaves as a hybrid liquid–gas ,fluid,. Unfortunately, there is a lack of experimental research about s-,CO 2,.
