Using Computational Modeling to Design Cleaner, More Fuel-Efficient Motor Vehicles
Replacement of conventionally powered vehicles with alternatively powered vehicles will likely accelerate as the new powertrain technologies mature. In the meantime, the focus will remain on improving the existing, conventional engine designs and relying on after-treatment devices to clean up emissions. Simulation software can play a valuable role in identifying cleaner, more fuel-efficient alternatives to improve engine designs. This paper discusses the scope and impact of the problem, and explains how CFD can be used to analyze emission-controlling devices and contribute to the achievement of emission standards.

Using Computational Modeling in the Development and Design of Alternative Powertrain Vehicles
With two out of every three people now concerned about climate change and governments concerned with the economic and political implications of volatile oil prices, new alternative powertrain technologies are needed to deliver zero, or near zero, emissions and improved fuel economy. Simulation software designed to optimize product development processes can play a valuable role in identifying cleaner, more fuel-efficient powertrain alternatives.

New Methods for Moving Toward Zero Emissions While Minimizing Cost
The primary challenge currently faced by the power generation industry is meeting the increasing consumer demand for electricity while reducing airborne toxic emissions in compliance with federal regulations. Emission reduction techniques generally fall into one of two categories: eliminating the pollutants at the source with improved combustion that optimizes heat transfer while minimizing pollutant formation, or removing them from the flue gas downstream.

Flow Modeling Helps Prove Hurricane Damage Caused by Wind, Not Water
A steel storage building located on a canal between downtown New Orleans and Lake Pontchartrain was damaged during Hurricane Katrina. The insurance company asserted that the damage, in which the walls were pushed outward in two areas, was water-related. Since insurance covered only wind damage, the claim was denied. TRC, representing the owners of the storage building, undertook a modeling study to investigate whether the strong winds could explain the damage.
