Abstract
A pump uses the steam hammer effect to pump water from a reservoir into a control volume. Steam is injected into a water conduit extending between a liquid water reservoir and the control volume forms a liquid steam interface. Steam within the conduit condenses on the interface creating a region of partial vacuum. Water accelerates into the region of partial vacuum and is vented into the control volume, flow being controlled by a valve.
