Chemically Reacting, Turbulent Shear Layer

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...

A-priori Testing of Sub-grid Models for Chemically Reacting Nonpremixed Turbulent Shear Ows

The assumed pdf approximation of Cook Riley is tested as a subgrid model for the LES computation of nonpremixed turbulent reacting ows in the limit of cold in nitely fast chemistry for two plane turbulent mixing layers with di erent degrees of intermittency Excellent results are obtained for the computa tion of integrals properties such as product mass fraction and the model is applied to other...

Forced Turbulent Shear Layer

Bubble breakup in a turbulent shear layer

The breakup of a millimetre size buoyantly rising bubble encountering a horizontal plane turbulent jet is experimentally investigated using high-speed shadowgraphy and acoustic techniques. The bubble diameter to jet height ratio is 0.75 and the jet height based Reynolds number is 4000. The high-speed imaging was recorded at 7 kHz simultaneous with hydrophone output at 100 kHz. Bubble breakup ev...
