An experimental method was developed to measure both steam-water and air-water capillary pressures using an X-ray CT technique. We conducted spontaneous water imbibition and gravity drainage in ceramic core samples for steam-water and air-water systems respectively. The results were compared, and it was found that the steam-water capillary pressures were significantly less than the airwater cap...

Computational simulation of steam flow and heat transfer in power plant condensers on the basis of the threedimensional mathematical model for the flow through porous media is presented. In order to solve the mathematical model of steam flow and heat transfer in power plant condensers, the Streamline Upwind Petrov-Galerkin finite element method is applied. By comparison of the results of simula...

Fluidic interconnects provide the passages for the transport of liquid analytes, containing mass and information, from one component to another in a microfluidic system. The pressure capacity of a novel, modular, gasketless, chip-to-chip microfluidic interconnect that forms a seal with a liquid bridge suspended between concentric through-holes was evaluated experimentally (see Figure 1). [5] Th...

in this research, water and steam absorption behavior and also effect of maleic anhydride polypropylene (mapp) on these behaviors in wood fiber-polypropylene composite were compared. for this purpose, the composites were manufactured from 60% fibers and 40% polypropylene in presence and absence of ma. the oven dried samples with dimensions of 2.5×2.5×1 cm were immersed in distilled water and ex...

In this work, char gasification of two coals (i.e., Shenfu bituminous coal and Zunyi anthracite) and a petroleum coke under a steam and CO2 mixture (steam/CO2 partial pressures, 0.025–0.075 MPa; total pressures, 0.100 MPa) and CO2/steam chemisorption of char samples were conducted in a Thermogravimetric Analyzer (TGA). Two conventional kinetic models exhibited difficulties in exactly fitting th...

This paper presents steam temperature models for steam distillation pilot-scale (SDPS) by comparing Pseudo Random Binary Sequence (PRBS) versus Multi-Sine (M-Sine) perturbation signal Both perturbation signals were applied to nonlinear steam distillation system to study the capability of these input signals in exciting nonlinearity of system dynamics. In this work, both linear and nonlinear ARX...

The most common wood species in Sweden, and one of the most important renewable raw materials in Northern Europe, is Norway spruce (Picea abies). Today, it is utilized mainly for sawed timber and the production of pulp and paper. A modern kraft pulp mill that produces bleached pulp has a material efficiency of about 40-45%, and the final product contains mainly cellulose. The other components o...

This article suggests the value in a broad view of STEAM beyond arts-integration, as well as the potential of design thinking for STEAM. Despite much interest in STEAM it is often challenging for many teachers to integrate into their teaching of school subject matter. I suggest that as an interdisciplinary crossroads, design thinking provides a natural bridge between the arts, sciences, and oth...

Research on achieving Class A material through thermophilic digestion at 55 C (131 F) in a continuously fed, single reactor configuration was performed at the Districts= Joint Water Pollution Control Plant (JWPCP) in Carson. Bench-scale (8.0 l) work showed that sufficient thermophilies for seeding purposes exist in mesophilic cultures at 35 C (96 F). After stable bench-scale thermophilic operat...

This paper aims to illustrate how the combination of Network Analysis and Futures Studies becomes a powerful instrument for envisioning and analyzing futures and social change. The study of three cases shows network analysis becoming an analytical tool in futures studies while, at the same time, acquiring the dimension of change and dynamics steaming from the futurist perspective.
