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...

A number of technological, institutional and market developments have lowered the minimally economic viable wind speeds for wind power generation while contributing to increasing profitability of the wind power industry in recent decades. Yet, information on the potential for wind power...

Pelton turbine (or Pelton wheel) is among the most efficient impulse turbines and has retained its existence in hydropower for well over a century. However unlike in the development of the reaction turbines, where Computational Fluid Dynamics (CFD) have been successfully applied for more than 20...

In a tangentially coal-fired boiler, for locations inside and near the combustor, heat-transfer by radiation is significant, and hence, ash particles arrive in molten state. The aim of the present study is to adopt a mechanistic modeling approach which incorporates energy-conservation principles...

In the present work, the performance of an updraft gasifier was investigated experimentally and numerically. This study aimed to use a two-dimensional model using a code, namely COMMENT code, to investigate the gasification and combustion processes while taking into consideration the process...

An experimental and numerical model of a solar chimney was proposed in order to predict its performance under varying geometrical features in Iraqi environmental conditions. Steady, two dimensional, turbulent flow was developed by natural convection inside an inclined solar chimney. This flow...

When preserving perishable goods, maintaining a constant temperature over the cold supply chain is essential. Therefore, refrigerated vehicles are an important part of the cold supply chain system. However, many traditional refrigerated cargo systems are not designed to support the homogeneity...
