Photoelectric Composite Three-Phase Flow Sensor for Complex Oil and Gas Wells. [PDF]
Sensors (Basel)Reliable measurement of multiphase flow is fundamental to production evaluation in complex oil and gas wells. However, conventional sensors often suffer from low integration, limited measurement capability, and potential environmental impact.

Characteristics of Bubbles and Gas Holdup In A Two-Phase Column For Different Liquid Phases [PDF]
Engineering and Technology Journal, 2007 Experimental study of gas holdup (Eg), bubble diameter (dvs) interfacial area(a) m-1, small bubble rise velocity (Ubs), and bubble rise velocity (Ubr) in (0.1mi.d) and (1.5m) high column operated at ambient temperature and pressureconditions.

The gas holdup in a multiphase reciprocating plate column filled with carboxymethylcellulose solutions [PDF]
Journal of the Serbian Chemical Society, 2005 Gas holdup was investigated in a gas–liquid and gas–liquid-solid reciprocating plate column (RPC) under various operation conditions. Aqueous carboxymethylcellulose (sodium salt, CMC) solutions were used as the liquid phase, the solid phase was spheres ...

Influence of the geometry on the riser gas holdup in an external-loop airlift reactor: empirical and neural network modelling [PDF]
Acta Periodica Technologica, 2018 Experimental studies on the effect of geometrical characteristics (restriction orifice free area and sparger configuration) on the riser gas holdup of an external-loop airlift reactor have been conducted in this paper. The impact of the addition

Information Design in the Holdup Problem [PDF]
Journal of Political Economy, 2020 We analyze a bilateral trade model where the buyer chooses the distribution of her valuation for the good. The seller, after observing the buyer’s distribution but not the realized valuation, makes a take-it-or-leave-it offer. If distributions are costless, the price and the payoffs of both the buyer and the seller are shown to be 1/e in the unique ...
