3D Numerical Study of Velocity Profiles and Thermal Mixing in Passive, Infrared Suppression Devices for Gas Turbine Engine Driven Generators

Abstract

A 3D numerical study was conducted and compared to experimental data from a venturi-type, infrared (IR) suppression device for exhaust ducting. The results, for a gas turbine driven generator, yield a novel design that is more compact and allows for shorter duct lengths, hence enabling associated camouflage netting to be lower in height and also reducing engine power loss due to reduced backpressure. Venturi-type, infrared suppression devices are of interest due to low-cost, low-maintenance, duct-type construction. This information is reported to demonstrate the value of virtual prototyping and testing for design optimization, hence impacting system design and providing the best product to the soldier.
