The Flowmaster Gas Turbine secondary air solver allows users to build up two dimensional models of the cavities within a gas turbine engine. It is a powerful tool for those engineers concerned with secondary or bleed air flows and allows them to understand the effects of swirl and heat transfer within and throughout the cavity.
Flowmaster’s ability to deliver accurate results for complicated fluid networks under high centripetal forces makes it an extremely capable design tool for those involved in the design of lubrication systems within gas turbine engines.
Purge Air Systems
Purge Air Systems are typically used on gas turbines that are equipped to run both liquid and gaseous fuels. High pressure air is pumped through the fuel lines to “purge” any remaining fuel from the lines and any possible contaminants. The pressure used is 20% to 30% higher than the normal operating pressures. In these instances Flowmaster compressible analysis can be used to determine proper flow rates and identify any possible choking locations.
