Ejector primary nozzle steam condensation: area ratio effects and mixing layer development
, 2014 Recent ejector simulations based on wet steam modeling give significantly different performance figures relative to ideal gas modeling, but the origins of such differences are not clear.

Journal of Chemical Technology &Biotechnology, EarlyView.Abstract Continuous neutral‐alcohol and food‐grade ethanol production is an energy‐intensive process in which distillation and rectification alone account for 50–85% of total plant energy use. While significant advances in separation technology have emerged over the past two decades, the spirits industry continues to rely predominantly on multi‐effect ...
