Gamma radiation methods for clamp-on multiphase flow metering [PDF]

, 2008
The development of a cost-effective multiphase flow meter to determine the individual phase flow rates of oil, water and gas was investigated through the exploitation of a single clamp-on gamma densitometer and signal processing techniques.

Highly Selective H2 Production From Photoreforming of Formic Acid Triggered by Cu Single‐Atom Sites in a Cocatalyst

Carbon Energy
Photoreforming of formic acid (FA) represents a compelling technology for green hydrogen (H2) production, but the application is limited by the relatively low activity and selectivity.

Optimizing the Mass Flow and Temperature Difference in a Cooling System for Energy Conservation [PDF]

, 1980
Conventional wisdom in recent times has been to raise the chilled water temperature to conserve chiller power. This is an effective and well-proven conservation strategy; however, it may be less optimal than other available alternatives. Reducing the fan

Interfacial exchange relations for two-fluid vapor-liquid flow : a simplified regime map approach [PDF]

, 1981
A simplified approach is described for selection of the constitutive relations for the inter-phase exchange terms in the two-fluid code, THERMIT. The approach used distinguishes between pre-CHF and post-CHF conditions.
