Supersonic combustion modelling using the conditional moment closure approach [PDF]
, 2014 This work presents a novel algorithm for supersonic combustion modelling. The method involved coupling the Conditional Moment Closure (CMC) model to a fully compressible, shock capturing, high-order flow solver, with the intent of modelling a reacting ...

Experimental and Numerical Study of Turbulent Flame Structures of a Spray Jet Flame
, 2017 The flame structure of a laboratory scale n-heptane spray flame is investigated experimentally and numerically. The experimental burner is an open chamber with an ambient temperature co-flow surrounding a hollow cone simplex atomiser. OH-PLIF measurements are performed to study the interaction between turbulence, droplets, and chemistry. The simulation

Experimental study of combustion and scalar mixing in swirling jet flows
Turbulent mixing of passive scalar field and combustion of gaseous fuel were studied in the context of a non-premixed isothermal and reacting swirling jets discharged from a swirl-stabilised burner, as a function of swirl number.

Investigation of Flame Stretch in Turbulent Lifted Jet Flame
Investigation of Flame Stretch in Turbulent Lifted Jet FlameDNS data of a laboratory-scale turbulent lifted hydrogen jet flame has been analyzed to show that this flame has mixed mode combustion not only at the flame base but also in downstream locations. The mixed mode combustion is observed in instantaneous structures as in earlier studies and in averaged structure, in which the predominant mode is found to ...
