AbstractData are presented on flow regimes, holdup and pressure drop for vertical co‐current two phase flow in a 0.026 m i.d. pipe. A universal flow regime map was not possible but flow regime transitional equations were developed for the slug to churn, churn to semi‐annular, semi‐annular to annular and annular to annular ripple boundaries.

We present real-time observations of a new growth pattern called a spiral two-phase dendrite, which we observed during univariant directional solidification of a ternary-eutectic alloy. Two different crystal phases grow from the apex of a parabolic finger, forming a spiral pattern that leaves behind in the solid a double helix microstructure.

A direct measurement of shaft angular acceleration may be made with a conventional drag cup tachometer operated as an accelerometer. In this operating mode the tachometer is supplied with direct current and provides a direct voltage proportional to acceleration.

A bi-directional two-phase/two-phase heat exchanger
28th Thermophysics Conference, 1993This paper describes the design and test of a heat exchanger that transfers heat from one two-phase thermal loop to another with very small drops in temperature and pressure. The heat exchanger condenses the vapor in one loop while evaporating the liquid in the other without mixing of the condensing and evaporating fluids.

Separated two-phase flow model: application to critical two-phase flow
International Journal of Multiphase Flow, 1983Abstract A separated flow model has been developed to allow the calculation of critical flow rates for steam-water mixtures. This model considers hydrodynamic as well as thermal non-equilibrium effects which are present due to rapid depressurization. Thus, this model incorporates interphase interaction terms for momentum, energy and mass.
