Xist^® 3.0 predicts negative pressure drops for some design cases with tubeside condensation under deep vacuum. We reviewed the momentum pressure drop method for condensation under vacuum conditions and modified the momentum recovery factor for tubeside condensation. This update greatly improves predictions of pressure drop, especially for condensation under deep vacuum conditions.
