This paper investigates the importance of network effects in the demand for ethanol-compatible vehicles and the supply of ethanol fuel retailers. An indirect network effect, or positive feedback loop, arises in this context due to spatially-dependent complementarities in the availability of ethanol fuel and the installed base of ethanol-compatible vehicles. Marketers and social planners are int...

This paper has studied fuel consumption in Nagel-Schreckenberg traffic flow model. The dependence of fuel consumption (per km per vehicle) on the average density ρ, the maximum velocity vmax, and the randomization probability p is studied. The relationship between fuel consumption and average velocity is also investigated. Our simulations indicate to minimize fuel consumption, different average...

in the presented research, heat transfer of a mobile electrolyte alkaline fuel cell (afc) (which the electrolyte has cooling role of system) has been considered. proper control volumes of system with specific qualification have been chosen. consequently, heat and mass transfer in control volumes have been assessed. considerations on them and contributed models lead to approve a double tube heat...

The present study is concerned with measuring and simulating soot formation and combustion in turbulent liquid fuel spray flames. Soot concentrations inside the combustor are measured by filter paper technique. The simulation is based on the solution of the fully-coupled conservation equations for turbulent flow, chemical species kinetic modeling, fuel droplet evaporation and combustion and...

Currently, the process design of fuel cells and the development of control strategies is mainly based on heuristic methods. Fuel cell models are often too complex for control purposes, or they are developed for a specific type of fuel cell and valid only in a small range of operation conditions. The application of fuel cell models to controller design is still limited. Furthermore, suitable and...

Despite widespread agreement that a carbon tax would be more efficient, many countries use fuel economy standards to reduce transportation-related carbon dioxide emissions. We pair a simple model of the automakers’ profit maximization problem with unusually-rich nationally representative data on vehicle registrations to estimate the distributional impact of U.S. fuel economy standards. The key ...

We develop a numerical model to simulate the impacts of overlapping energy policies on carbon emissions in the U.S. personal transportation sector. Consumers in our model demand fuel based on their underlying demand for miles and choices about car fuel economy; firms supply fuel by blending gasoline with corn, sugarcane, and cellulosic ethanol. We find that the current fuel tax, size-based fuel...

Fuel substitution in OECD-European electricity production is described by a putty-clay formulation. At the time of investment, fuel shares are determined according to a logit model. These fuel shares are maintained throughout the lifetime of the power plants. However, a significant share of capacity is assumed to be flexible. Short-term fuel switching is described by a logit model. An attempt h...
