Abstract The arylhydrazones of ethyl α‐oxo‐cyanoacetate 1a – e and the α‐arylhydrazones β‐phenyl‐α,β‐diketopropionitrile 2a , react with G RIGNARD reagents at room temperature to yield cyanocarbinols 3a h . On other hand, 1 2 phenylmagnesium bromide in refluxing ether‐benzene mixture, imino derivatives 4a d are dehydrated by hot acetic acid compounds 5a Similar treatment 41 affords α‐arylazo‐β‐phenylchalcones 6a which hydroxylamine isoxazoline 7a Treatment 1b ethereal diazomethane results...

In the present study, two measurement techniques are adopted to evaluate fuel–air mixing under atmospheric conditions using an industrial premixer. These CO2 and planar laser induced fluorescence (PLIF) in water. these techniques, fluorescent dye injected as fuel simulants. measurements used validate PLIF technique, concentrations converted mass fractions, whereas a modified post processing method is convert LIF signal into fraction. The experiments conducted at same Reynolds number momentum...

A novel airblast injector is designed for gas turbine combustors. Unlike standard pressure swirl and prefilming/non-prefilming air blast atomizers, the to improve fuel injection delivery atomization of by using a porous stainless steel tube. There are three swirling streams in injector. The liquid injected through tube, with 7 micron porosity, between streams, viz. an inner tube other two merging downstream vane angles split ratio selected increase amount facilitate process. outer surface...

In the present investigation, a novel fuel injection concept is developed for Dry Low NOx combustors. A multi-injector block used fuel-air mixing and flame stabilization. The injectors in are equally spaced rectangular grid of 3×3. Each injector has porous concentric tube through which injected into annular space around tube. made up stainless steel with 30 μm porosity. Air enters eight tubes that surround air mix between wall CO2 technique adopted to investigate quality under non-reacting...

The Combustion and Fire Research Laboratory (CFRL) at the University of Cincinnati (UC) is working on development advanced next generation injectors for DLN combustors. Several inputs were received from project partners during phase. In present paper, developmental work two novel with Porous Injection Technology (PIT) presented. technology has potential to reduce NOx emissions single digit PPM level a stable combustion across wide range load conditions. One key factors that are essential...
