Shade-grown coffee provides a livelihood to many farmers, protects biodiversity, and creates environmental services. Many shade-coffee farmers have abandoned production in recent years, however, in response to declines in international coffee prices. This paper builds a farmer decision model...

This paper presents a new hybrid methodology for the determination of the effective heat capacity (Ceff) of phase change materials (PCMs) for use in numerical models. The methodology focuses on PCM enhanced building panels utilizing a heat flow meter apparatus (HFMA) operating in dynamic mode...

In this study, the effect of an applied electric field on the separation and rise of bubble was simulated by Computational Fluid dynamics and results were compared with experimental data. The numerical results showed proper agreement (10%) with experimental reports. The working fluids in the...

Molasses is a first-generation bioethanol feedstock that is a byproduct of sugar production. Molasses is a viscous fluid; consequently, when it serves as a substrate, it needs to be dissolved in water to obtain the appropriate conditions for the yeast. Therefore, the mixing process of molasses...

All modern hydro-kinetic turbines are being designed based on a lift, using airfoils, which should have a significant lift to drag ratio to achieve maximum efficiency.SG604X family airfoil has significant lift-to-drag ratio under an operating range of Re from 105-106, which also come under our...

Supersonic Ejector (SE) is a thermally-driven fluidic compressor that replaces the electro-mechanical compressor in Reverse-Rankine refrigeration/heat pump cycles. These widely used thermal cycles account for billions of kWh of electric energy and produce hundreds of millions of metric tons of...

The present work seeks to review the current biomass combustion models in use for industrial applications. Combustion efficiency of coal fired boilers is a major concern for engineers and policy makers especially with the effect emissions have on the climate. Biomass, a renewable fuel, offers an...
