Void Fraction Correlation for Boiling and Non-Boiling Vertical Two-Phase Flows in Tube

A General Correlation for Saturated Two-Phase Flow Boiling Heat Transfer Inside Horizontal and Vertical Tubes

A simple correlation was developed earlier by Kandlikar (1983) for predicting saturated flow boiling heat transfer coefficients inside horizontal and vertical tubes. It was based on a model utilizing the contributions due to nucleate boiling and convective mechanisms. It incorporated a fluid-dependent parameter Ffl in the nucleate boiling term. The predictive ability of the correlation for diff...

Computations of Boiling Flows

A numerical method to simulate liquid-vapor phase change is presented. The method is based on the so-called single eld formulation where one set of equations for conservation of mass, momentum, and energy are written for the entire ow eld. Interfacial source terms for surface tension, interphase mass transfer and latent heat are added as delta functions that are non-zero only at the phase bound...

Experimental Investigation of Boiling and Condensation Heat Transfer of a two Phase Closed Thermosyphon

In this paper the heat transfer characteristics of a two-phase closed thermosyphon over a wide range of heat transfer rates, system pressure, aspect ratios and filling ratios were studied. The experiments focused on the boiling and condensation heat transfer characteristics of the thermosyphon. The experimental boiling and condensation heat transfer coefficients inside the thermosyphon were com...
