Research Abstract |
In this study, flame speed and shape will be investigated. Experimental
research will be conducted using two vessels, spherical and cylindrical
systems. Premixed fuel-oxidizer mixtures will be centrally ignited in
the spherical vessel. Dynamic rise of pressure will be measured. A thermodynamic
model will be used to calculate flame speed as a function of unburned
gas temperature, pressure and fuel-air mixture equivalence ratio. Experiments
will be done for different fuel-air mixtures at different initial temperatures
and pressures. The cylindrical vessel has two large windows for optical
measurements. A camera with capability of 8000 frames per second is used
to observe flame propagation. Flame shape, cracks and cellularity will
be investigated using the optical set up.
