TS-038711 — A mixed surfactant solution consisting of a zwitterionic surfactant and cationic surfactant with an added counterion ("ZwitCat solution") which demonstrates switchable and improved drag-reduction ability at a wide range of compositions, flow rates, and temperatures
Large-scale recirculating heating and cooling systems, such as those for regional, district, and single-building applications, require a working fluid to be pumped across large distances from the heat source to the consumer. While large-scale systems like district heating are more energy efficient…
