• A new hybrid humidification–dehumidification and air conditioning system is proposed and investigated. • The proposed system keeps the function of the air conditioning system and uses it in water desalination. • The effects of system operating parameters on system performance were evaluated and correlated. a b s t r a c t a r t i c l e i n f o An experimental study of the performance of a hyb...

ENSC 461 (S 11) Gas Vapor Mixtures and HVAC 1 Gas Vapor Mixtures and HVAC Atmospheric air normally contains some water vapor (moisture). The dry-air contains no water. Although the amount of water vapor in the air is small, it plays a major role in human comfort and thus in air-conditioning applications. The temperature of air in air-conditioning applications ranges from about -10 to 50°C. In t...

Using the techniques of optical microscopy and particle tracking, we measure the correlated diffusion in a monolayer of uniform silica spheres dispersed at a water-air interface. It is found that the correlated motion of the interfacial particles can be well described by two universal response functions, the normalized longitudinal and transverse diffusion coefficients D(∥)(r/r0) and D(⊥)(r/r0)...

A comparative analysis of air-water flow properties was performed between two geometrically scaled stepped spillway models with step height of 5 and 10 cm respectively. The experiments were conducted in the same large size facility with chute slope of 26.6° and with the same phase-detection intrusive measurement devices. A full range of macroand microscopic air-water flow properties was tested ...

This paper discusses the verification and application of the three-dimensional (3-D) multiphase flow model presented by Huyakorn et al. (Part I in this issue) for assessing contamination due to subsurface releases of non-aqueous-phase liquids (NAPL's). Attention is focussed on situations involving one-, twoand three-dimensional flow through porous media. The model formulations and numerical sch...

Previous work has shown that the ventilation of nitric oxide (NO) from the maxillar sinuses is affected not only by the steady air stream through the nasal tract, but also if this air stream is modulated by vocal fold activity. In order to explain the increased ventilation during such nasal murmur two models were built; one physical model, and one computer model of this physical model. This pap...

Partition coefficients of hydrophilic organic solvents (C1-C5 acetate esters and alcohols) in distilled water, olive oil, human blood, and various rat tissues (blood, liver, kidney, brain, muscle, and fat) were determined. Water/air partition coefficients were measured by a new vial equilibration technique, which needs no direct measurement of the concentration in either the liquid phase or the...

Water/air, blood/air, oil/air, oil/water, and oil/blood partition (or solubility) coefficients of 17 aromatic hydrocarbons and ketones were measured by a newly developed vial-equilibration method, which needs no direct measurements of the concentration either in the liquid or in the air phase, but only the gas chromatographic peak heights of the air in the sample (in which a test material is co...

We describe the implementation of a fluid dynamical benchmark on the 256 node SUPRENUM-1 parallel computer. The benchmark, the Shallow Water Equations, is frequently used as a model for both oceanographic and atmospheric circulation. We describe the steps involved in implementing the algorithm on the SUPRENUM-1 and we provide details of performance. We have measured 4.95 Mflops (64-bit arithmet...
