Fingerprints of surface flows on solid substrates ablated by phase change: from laboratory experiments to planetary landscapes by Carpy, Sabrina, Berhanu, Michael, Chaigne, Martin, Courrech du Pont, Sylvain

“…In many situations, these layers are controlled by fluid flow, either natural or forced convection. In the former case, the flow may be buoyancy driven by the melting/dissolution/sublimation itself, resulting in density stratification caused by, for example, temperature/concentration gradients. …”
