Experimental study of flooding phenomenon in a power plant reflux air-cooled condenser
TL;DR: In this paper, three two-phase flows are identified: (i) the start of droplet entrainment at the tube bottom, (ii) the post-flooding, and (iii) the flooding onset.

Multi-scale study of wet pressure drop model for a novel structured wire gauze packing
TL;DR: In this paper, a novel type of structured wire gauze packing was designed, investigated, and compared with initial packings to improve hydrodynamic performances, especially in reducing the wall flow phenomenon and lowering pressure drop.

A Simple Model to Identify Dryout Location: Validation and Computational Fluid Dynamics Predictions
TL;DR: In this article, a simple model is proposed to predict the dryout location of a thermal system in order to identify reliable heat flux margins for the safe operation of different thermal systems.

Boundary layer theory
TL;DR: The flow laws of the actual flows at high Reynolds numbers differ considerably from those of the laminar flows treated in the preceding part, denoted as turbulence as discussed by the authors, and the actual flow is very different from that of the Poiseuille flow.

Flooding in tubes and annuli
TL;DR: In this article, a new flooding correlation is presented which solves the obvious contradiction between the Wallis correlation and the study by Pushkina and Sorokin concerning the scaling question at zero penetration of liquid.

Air-water countercurrent annular flow
D. Bharathan,Graham B. Wallis +1 more
TL;DR: In this paper, the authors investigated the effect of tube end geometries on measured countercurrent fluxes, liquid fraction, and pressure gradients, and analogies between countercurrent gas-liquid flow and other more familiar flows in internal geometry are indicated.

Flooding and churn flow in vertical pipes
TL;DR: In this paper, a 32 mm dia vertical pipe with various forms of liquid outlet, namely a porous wall, a tapered outlet, and a square-edged outlet, was used to investigate the effect of churn flow on the penetration rate.
