The Relative Impacts of U.S. Bio-Fuel Policies on Fuel-Energy Markets: A Comparative Static Analysis

The Relative Impacts of U.S. Bio-Fuel Policies on Fuel-Energy Markets: A Comparative Static Analysis

Rapidly declining gasoline prices from their record high during the summer of 2008, while ethanol prices remained relatively high, made it difficult for many bio-fuel policy modelers to fully explain the impacts of U.S. bio-fuel policies on fuel prices. Using profitmaximization models for blenders, refiners, and distillers, we conduct a comparative static analysis to measure the relative magnit...

Comparative Analysis of a Single Fuel Droplet Evaporation

In this research, the results of comparative analysis of a single fuel droplet evaporation models are presented. Three well-known evaporation models including Spalding, Borman-Johnson and Abramzon-Sirignano models are analyzed using Computational Fluid Dynamic (CFD). The original Spalding model is extended to consider the effects of the Stefan flow, unsteady vaporization, and variable propertie...

a comparative pragmatic analysis of the speech act of “disagreement” across english and persian
