Locomotive Diesel Exhaust

Rail Diesel Exhaust Analysis for Legal Cases

As of 2021, Airflow Sciences Corporation (ASC) has consulted on eleven legal cases where the train operators’ exposure to diesel exhaust was evaluated.

The Role of CFD in a Legal Proceeding

The Role of CFD in a Legal Proceeding

In legal cases that rely on technical details, engineers are oftencalled upon to perform engineering analysis or testify as expert witnesses.

Balanced Mill

Air and Coal Balancing for Improved Combustion

The air to fuel ratio is important for combustion efficiency. By adjusting the coal and air flow to within acceptable balanced standards, coal pipe balancing is achieved.

SCR Tuning schematic

SCR Tuning

Gas analyzer equipment is used to measure the SCR performance. Testing personnel then tune the AIG to minimize ammonia consumption.

Simple Cycle Temperature Profile

Simple Cycle Systems and HRSGs

CFD flow modeling of simple cycles or HRSGs can improve uniformity of velocity, temperature, and ammonia, as well as minimize the pressure drop.

V-22 Osprey Cabin

V-22 Osprey Cabin Cooling System Upgrade

A physical model of the HVAC ducting system of a V-22 aircraft was constructed in order to test the flow balance and to verify an improved duct design.

Ocean Research MBARI cfd

Helping Advance Ocean Research

CFD analysis of aerodynamics was used to determine whether a long-range, high-speed vehicle was feasible based on current energy storage technology.

Thermal Stratification in Ductwork

Innovative Mixing Device Reduces Thermal Stratification in Ductwork

A coal plant experienced temperature stratification in its pulverizer inlet ductwork. A CFD model was used to design and optimize an air mixer device.

Optimizing SCR

Optimizing SCR Performance

A physical model and CFD analyses were used together to generate a uniform velocity profile and provide consistent NOx ratios, despite severe stratification in the SCR.

Temperature Mixing

Temperature Mixing Solutions

"Cold zones" in an ESP increased the risk of metal corrosion. A CFD model of the flow patterns was used to develop a customized mixer to reduce the thermal gradient.

Coal Pipe Balancing

Coal Pipe Balancing

Coal pipe balancing can ensure that emissions are reduced and combustion efficiency is improved. Duct field testing of existing pipe geometry and subsequent analyses can optimize flow control devices.

Particulate Emissions

Particulate Emissions Reduction

Flow distribution through particle collection systems has a major influence on pollution control. Flow control baffles designed for this ESP not only improved flow, but also minimized potential for flyash accumulation.

Interior Heating/Cooling

Vehicle Interior Heating & Cooling

A CFD model simulated the radiative heat transfer from the sun, and the temperature of the vehicle interior was computed. The effectiveness of different glass types was quickly evaluated by changing glass transmission assumptions.

Panel Duct

Panel Duct & Register Development

Applied in conjunction with testing, numerical analysis techniques allowed our engineers to design panel duct systems with optimal flow balance.

Defrost System

Defrost System Development

CFD analysis evaluated various defrost system designs. A time-dependent simulation showed the rate at which heat was transferred from the warm defrost air through the windshield glass and, finally, to the ice.

Racing Helmet

Racing Helmet Design

Wind tunnel testing was used to evaluate improved helmet designs, greatly reducing violent drag forces on the Indy car driver.
