99-11: Advanced Airfoils for Cooling Tower Fan BladesThe objective of this study was to explore the benefits of advanced airfoil technology for industrial cooling tower fan blades. An existing fan performance prediction code was used to identify desirable airfoil characteristics for large tapered twisted blades. The Eppler Airfoil design and analysis Code was then used to design advanced airfoils for the bade root and tip region. Results show and new airfoils allow a 20% reduction in blade chord

Dosage optimization requires sounds mathematical models for inhibitor dosages

The result is technology that continuously monitors the efficacy of any oxidizing microbiocide program and adjusts oxidant feed automatically based on system cleanliness and demand
