Abstract: This paper presents energy end-use model of the U.S. Chemical Industry. The model allocates combustible fuel and renewable energy inputs among generic end-uses including intermediate conversions ...

Abstract: This paper gives a representative energy process-step model of hydrogen production in the U.S. Chemical Industry based on federal data. There have been prior efforts to create energy process-step ...

Abstract: Carbon particles can be used as catalyst in solar reactors where they serve as radiant absorbent and nucleation sites for the heterogeneous decomposition reaction. Unlike commonly used metal catalysts, carbon catalyst does ...

Abstract: The numerical characterization of a 10 kWe xenon arc high flux solar simulator is thoroughly presented and performed using two approaches: a forward Monte Carlo ray tracing (MCRT) method and an inverse ray tracing method. ...

Abstract: Hydrogen is a high energy content fuel and methane is currently the most preferred feedstock for hydrogen production. Direct thermal splitting of methane offers the cleanest technique to produce hydrogen and carbon as ...

Abstract: Variable aperture mechanisms are being used in many fields including medicine, electronics, fluid mechanics, and optics. The main design characteristics of these aperture concepts are the use of multiple blades regulating ...

Abstract: This study focuses on a technique, referred to as “solar cracking” of natural gas for the coproduction of hydrogen and carbon as byproduct with zero emission footprint. Seeding a solar reactor ...

Abstract: Despite the significant potential of solar thermochemical process technology for storing solar energy as solid-state solar fuel, several challenges have made its industrial application difficult. It is important to note ...

Abstract: Abstract. Biomimetic designs draw inspiration from biological organisms for engineering design. This paper presents a design and analysis of multiple-piece winglets based on the wingtip feathers of birds. The biomimetic ...

Abstract: With reducing energy demand and required installed mechanical system power of modern residences, alternate heat pump system configurations with a possible increased economic viability emerge. Against this background, this ...
