Effects of heat release in a turbulent, reacting shear layer
Experiments were conducted to study the effects of heat release in a planar, gas-phase, reacting mixing layer formed between two free streams, one containing hydrogen in an inert diluent, the other, fluorine in an inert diluent. Sufficiently high concentrations of reactants were utilized to produce adiabatic flame temperature rises of up to 940 K (corresponding to 1240 K absolute). The temperat...
متن کاملMixing and Reaction at Low Heat Release in the Non-Homogeneous Shear Layer
The effects of freestream density ratio on the mixing and combustion in a high Reynolds number, subsonic, gas-phase, non-buoyant, two-dimensional turbulent mixing layer, have been investigated. Measurements of temperature rise (heat release) have been made which enable us to examine the effect of f reestream density ratio on several aspects of the mixed fluid state within the :urbulent co~busti...
متن کاملMixing and combustion with low heat release in a turbulent shear layer
Turbulent mixing and combustion are investigated in a gaseous shear layer formed between two streams: one containing a low concentration of hydrogen in nitrogen and the other containing a low concentration of fluorine in nitrogen. The resulting temperature field is measured simultaneously at eight points across the width of the layer using fast-response cold-wire thermometry. The results show t...
متن کاملA Model for Shear Layer Effects on Engine Noise Radiation
Prediction of aircraft engine noise is an important aspect of addressing the issues of community noise and cabin noise control. The development of physics based methodologies for performing such predictions has been a focus of Computational Aeroacoustics (CAA). A recent example of code development in this area is the ducted fan noise propagation and radiation code CDUCT-LaRC. Included within th...
متن کاملEntrainment and spreading of turbulent shear flows
Over the last decade there has been a renewed interest in understanding the entrainment process in turbulent shear flows [5]. Even though there are differences between the way different shear flows (such as jets, wakes, boundary layers and shearfree flows) develop [14], the origin of these differences is not clear. Here, employing experimental data from an axisymmetric turbulent jet and a turbu...
