Numerical investigations of highly complex flow systems, such as the aero-thermal flow through an entire aircraft gas turbine engine, require the application of multiple specialized flow solvers in order to compute the flow efficiently and accurately. The flow solvers have to run simultaneously in order to capture unsteady multi-component effects. The(More)
Multi-component effects, such as compressor-combustor interactions, are difficult to predict with computational fluid dynamics using reasonable computational resources due to the variety of physical phenomena, which have to be modeled. The approach described in the present study is to couple two separate flow solvers, a RANS flow solver computing the last(More)
Turbulent flame brush thickness is a characteristic measure of the transition zone between the burned and unburned states of a premixed flame. It may be interpreted as the square root of flame position variance, and must be accurately described if the flow properties and heat release characteristics of a premixed flame are to be captured. In this work the(More)
