Flow regime-based modeling of heat transfer and pressure drop in microchannel flow boiling

Local heat transfer coefficients and pressure drops during boiling of the dielectric liquid fluorinert FC-77 in parallel microchannels were experimentally investigated in recent work by the authors. Detailed visualizations of the corresponding two-phase flow regimes were performed as a function of a wide range of operational and geometric parameters. A new transition criterion was developed for...

Mechanistic Modeling of the Liquid Film Shape and Heat Transfer Coefficient in Annular-Regime Microchannel Flow Boiling

Numerical Simulation of Water Mist Suppression of Tunnel-fire Scenarios

Water-mist fire suppression systems offer a number of potential advantages over conventional sprinkler systems. A water-mist system uses very fine droplets of around 50μm diameter, which results in entirely different behaviour. In particular the water-mist remains suspended in air for long periods, and is influenced by the airflows caused by the fire and the general ventilation regime. In order...

Numerical simulation of growth of a vapor bubble during flow boiling of water in a microchannel

The present study is performed to numerically analyze the growth of a vapor bubble during flow of water through a microchannel. The complete Navier– Stokes equations, along with continuity and energy equations, are solved using the SIMPLER (semi-implicit method for pressure-linked equations revised) method. The liquid–vapor interface is captured using the level set technique. The microchannel i...
