Cavitation refers to the formation of bubbles in a liquid flow leading to a two-phase mixture of liquid and vapor/gas, when the local pressure drops below the vapor pressure of the fluid. Fundamentally, the liquid to vapor transition can occur by heating the fluid at a constant pressure, known as boiling, or by decreasing the pressure at a constant temperature, which is known as cavitation. Sin...

Today, the correct understanding of issue oil and water cavitation is important due to growing demands on working conditions in hydraulic systems (pressure flow rate). This article deals with measurement subsequent mathematical modeling a convergent-divergent nozzle circular cross-section. Cavitation depends physical properties flowing medium as function temperature. Usually, defined by two-pha...

The growth of molecular organic thin films by the process of organic vapor phase deposition (OVPD) was initiated by Professor Steve Forrest OVPD transports organic molecules to a cold substrate by a hot inert carrier gas. It has proven useful for the deposition of organic semiconductors, and is capable of patterned growth with micron resolution. Professors Benziger and Forrest collaborated to e...

We discuss the calibration and use of water vapor radiometers used for atmospheric phase correction on the BIMA array. Over intervals of a few minutes the WVR corrected data are consistent with the thermal noise of 100 microns. On longer time scales the calibration is currently limited by variations in the WVR passband and the atmospheric scale factor between the brightness of the water line an...

Astronomical arrays operating at (sub)millimeter wavelengths are seriously compromised by rapid variations in atmospheric water vapor that distort the phase coherence of incoming celestial signals. The signal received by each antenna of the array suffers a phase delay that varies rapidly with time and from antenna to antenna. Unless corrected, these distortions limit the coherence time of the a...

The effects of the finite size of a liquid drop undergoing a phase transition are described in terms of the complement, the largest (but mesoscopic) drop representing the liquid in equilibrium with the vapor. Vapor cluster concentrations, pressure, and density from fixed mean density lattice gas (Ising) calculations are explained in terms of the complement generalization of Fisher's model. Acco...

We have identified a fourth archetype of phase diagram in binary symmetrical mixtures, which is encountered when the ratio of the interaction between the unlike and the like particles is sufficiently small. This type of phase diagram is characterized by the fact that the lambda line (i.e., the line of the second-order demixing transition) intersects the first-order liquid-vapor curve at densiti...
