Introduction

Dr. Linfield, P.Eng., P.E. is a registered Professional Engineer in Ontario and Michigan. He is Engineering Director of Airflow Sciences Corporation and has been with the company since January 2000. He has managed and performed hundreds of distinct client projects using CFD (computational fluid dynamics), laboratory, and field testing skills. Applications include electrostatic precipitators, fabric filter systems, HRSGs and simple cycle systems, gas turbines, flow mixing devices, and fossil fuel boilers for power generation, mining, and other industries. Legal experience includes engineering evaluation of locomotive exhaust plumes to ensure a safe environment for operators and switch yard personnel. His attendance at the American Academy of Forensic Sciences Convention provided insight into opportunities for ASC's engineering expertise beyond the rail industry.

Dr. Linfield's work has been presented and published at MABS, CFDSC, COAL-GEN, ChemShow, and CANCAM conferences. He has been an invited speaker at Project Management and Quality Control seminars on the topic of PM and QC for Small Companies, and at electric power industry seminars on the topic of electrostatic precipitator optimization. He provides courses and seminars, such as "Flow Modeling" and "Field Testing", for Continuing Education (CE) and Professional Development Hours (PDHs) recognized by most states and provinces. Prior to joining ASC, Dr. Linfield had worked for CAE Inc, Ontario Hydro, Toyota Canada, the University of Toronto, and Netron.

Airflow Sciences Corporation (ASC) was founded in 1975 to provide engineering design and analysis in the areas of fluid flow, combustion, and heat transfer. ASC specializes in numerical flow simulation and aerodynamic testing. Our expertise includes physical and CFD flow modeling, field testing, data acquisition systems, and custom test equipment fabrication. Advanced technologies developed in the aerospace industry are applied to fluid flow problems in a variety of industries, including power generation, pollution control, food processing, automobile production, and computer software development. ASC consultants include mechanical, aerospace, and chemical engineers with advanced degrees, professional engineering licenses, and over 25 years of industrial experience. Previous legal project experience includes failure mode analysis, liability litigation testimony, environmental engineering analysis, root cause evaluation, compliance audits, and intellectual property infringement research.
