Furthermore, the detailed nano-structure of soot particles is analyzed to identify the source of combustion emissions. The effect of turbulence on the soot field is also evaluated by means of the analysis of the scattered signal. This is simply because of the fact that turbulent flames are extremely difficult to investigate due to unsteadiness in the flow field. A logical step towards the ultimate goal of adequately characterizing turbulent flames is to investigate relatively simple laminar flames that are forced by a time-varying flow field. Motivated by these observations, an experimental investigation of the properties of steady and unsteady soot-containing flames is proposed.
Hydrocarbon fuels used include methane, ethylene and acetylene.
Different steady strain rates and amplitudes and frequencies of the forced unsteady strain rates are considered. University of Missouri Research Board Each semiconductor emits or responds to light in a different wavelength range, so that each has special uses for different optoelectronic devices. The dramatic increase in the density of devices in integrated circuits and other devices has led to a demand for better crystals with fewer dislocations and other microdefects and with more uniform and controllable dopant compositions. The performance of a semiconductor is directly related to the uniformity of its composition. The objectives of the proposed research are to understand, predict and control the dopant composition using a magnetic field.
