Measurement and Analysis of Vitiation of Secondary Air in Air Distribution Systems (RP-1276)
HVAC&R Research, 2008Appendix A of ANSI/ASHRAE Standard 62.1-2007, Ventilation for Acceptable Indoor Air Quality, describes the recycling of unvitiated ventilation air in a recirculating air-handling system. Equation A-2 considers air delivered through the primary air path (central air distribution system) and secondary air paths, such as fan-powered boxes or transfer-air ...

On the Performance of Gas Turbine Secondary Air Systems
Volume 3: Heat Transfer; Electric Power; Industrial and Cogeneration, 2001The paper proposes a straightforward technique to quantify the performance of a gas turbine secondary air system. By recognising the air system as a component in its own right and performing the calculations suggested the systems engineer should be better able to develop and optimise a given air system.

Simple Particle Separator for the Secondary Air System of Gas Turbines
Volume 4: Heat Transfer, Parts A and B, 2012In heavy-duty gas turbines as well as in aero-engines, air is extracted from the compressor and led to the hot parts of the combustor and the turbine in order to cool them. Despite active design solutions such as material selection, and inclusion of compressor inlet filters, dust holes, and so on, the cooling air can be charged with solid particles ...
