Influence of a Flow Obstacle on Boiling Two-Phase Flow

ASME 2011 Power Conference, Volume 1, 2011
The spacer of Boiling Water Reactor (BWR) becomes the flow obstacle. Moreover the clearance between fuel rods of the innovative Water Reactor for Flexible fuel cycle (FLWR) becomes very narrow. Thus understanding of the thermal-fluid characteristics in the boiling channel equipped with the flow obstacle becomes more important. In this study, to clarify

Two Phase Boiling and Flow Instabilities in a Microchannel

ASME 5th International Conference on Nanochannels, Microchannels, and Minichannels, 2007
Boiling in microchannels is a very efficient mode of heat transfer. High heat and mass transfer coefficients are achieved. Evaporation of the liquid meniscus is the main contributor to the high heat fluxes achieved due to phase change at thin liquid films in a microchannel. The microscale hydrodynamic motion and the mechanisms at the immediate vicinity

Flow boiling heat transfer and two-phase flow in microgravity

Proceedings of the 15th International Heat Transfer Conference, 2014
Flow boiling heat transfer can provide high heat transfer rates due to latent heat transportation. Its possible use is therefore potentially important to reduce size and weight of cooling systems in space platforms and satellites. A comprehensive knowledge is also important for the safe operation of existing single-phase systems in case of accidental ...

Boiling two-phase flow under microgravity

Nuclear Engineering and Design, 1994
To study the effects of reduced gravity on the flow regime and the heat transfer characteristics of a boiling two-phase horizontal flow, parabolic flight experiments were performed by using an aircraft. The gravity level during the parabolic flight and the duration time were about −0.01ge ∼ +0.01ge and 20 s, respectively.

Wall function approach for boiling two-phase flows

Nuclear Engineering and Design, 2010
Abstract One of the important goals of the NURESIM project is to assess and improve the simulation capability of the three-dimensional two-fluid codes for prediction of local boiling flow processes. The boiling flow is strongly affected by local mechanisms in the turbulent boundary layer near the heated wall. Wall-to-fluid transfer models for boiling
