TechTip: Momentum Recovery in Tubeside Vacuum Condensers

Traditionally, for tubeside vacuum condensers, designers attempt to ensure that the velocity profile through the exchanger decelerates from the inlet nozzle to the outlet nozzle. Momentum recovery occurs with a reducing velocity profile throughout an exchanger. If correlations do not account for momentum recovery in the inlet and outlet header of tubeside condensers with decelerating velocity profile, predictions of pressure drop are conservative. Based on a presentation from the 2016 HTRI Global Conference and Annual Meeting of Stockholders, this webinar discusses the challenges that condenser designers encounter with momentum recovery in vacuum condensers and how to address them in Xist^®.
