Only a limited analytical approach to the problem of Direct Contact Condensation (DCC) in horizontal stratified flow is possible, therefore experiments are necessary. Two frequently used correlations for heat and mass transfer during the DCC in stratified flow were derived from experimental results by Lim [24] and Kim, Lee and Bankoff [20].

Recently Chu et al. [5], Lee et al. [8] investigated an interfacial condensation heat transfer in a stratified smooth and wavy liquid flow in a horizontal pipe, respectively.

Condensation induced water hammer (CIWH) in horizontal pipes Condensation induced water hammer (CIWH) in horizontal pipes is a safety issue for various fields of engineering including nuclear (Griffith, ).

The phenomenon starts with direct contact condensation of steam on subcooled liquid in horizontally stratified flow. The phenomenon starts with the direct contact condensation of steam on the subcooled liquid in horizontally stratified flow. Condensation induced acceleration of vapour and liquid may results in slug formation.

Once the slug is formed, a rapid condensation of the bubble entrapped behind the slug may follow, resulting in a strong pressure by: Direct-contact condensation of pure steam on co-current and counter-current stratified liquid flow in a circular pipe February International Journal of Heat and Mass Transfer 52() Maron and Sideman theoretically analyzed and compared the vapor condensation rate inside horizontal conduits for co-current and counter-current flow of steam and the accumulated condensate at the bottom of the tube, and investigated the heat transfer by a direct-contact condensation in a stratified two-phase flow at high system pressure and Cited by:   I want to simulate stratified flow of steam and water with CFX in 2-D rectangular geometry.

experimentally direct contact condensation of saturated vapor on the water droplets and effects of droplet diameter and velocity on the heat transfer rate. Kulic and Rhodes [9] developed a model to obtain the temperature fields of direct contact condensation of air-vapor mixture on the Size: 1MB.

steam flow rate increases significantly, momentum introduced by the steam injec-tion and/or periodic expansion and shrink of large steam bubbles due to direct contact condensation can cause breakdown of the stratified layers and lead to mixing of the pool water.

Accurate prediction of. When subcooled water in accumulator tanks is injected during a loss-of-coolant accident of a pressurized water reactor, violent condensation takes place in cold legs because of direct contact of steam with water. A flow model based on the multifluid model of the two-phase flow has been developed to formulate the condensation and mixing Cited by: 4.
