Dr. Franklin, P.E. is a registered Professional Engineer in the state of Michigan. He is Director of CFD and has been with Airflow Sciences Corporation since June 1993. Dr. Franklin has been the lead developer of many complex CFD software tools for ASC. These include:
• Program COMBUST, an equilibrium chemistry model for simulation of fossil fuel combustion.
• Program TWOPHASE, for simulation of gas streams with heavy particulate loading. Enhancements incorporate particulate drying and evaporation, including drying of wet solids, such as coal or cement, and evaporation of liquid droplets.
• Program NOx, which is used in conjunction with COMBUST to predict nitrous oxide formation in coal-fired power plants.
• Azore® software suite, a collection of CFD tools that includes an arbitrary polyhedral control volume solver and a graphical user interface. Dr. Franklin has driven the development of this software for over 20 years. With his guidance this tool has successfully transitioned from a specialized research package to a commercial package that is distributed and supported by Azore Software, LLC.

Dr. Franklin has also developed software for several client-specific applications, such as:
• A finite-rate chemistry model for the accurate prediction of chemical reactions in a CO catalyst.
• Particulate build-up (or slag formation) in a utility furnace.
• Ammonia injection for power plant SCR catalysts.
• Heat treating of forged and cast metal parts for automobile engines.
• Automated CAD model and CFD mesh generator for cooling tower design.

Dr. Franklin has acted as an Adjunct Faculty Member at Lawrence Technological University, Mechanical Engineering, 2005 – 2007.

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.
