  • Characterization of Six Clustered Methane-Air Diffusion Microflames through Spectroscopic and Tomographic Analysis of CH* and C2* Chemiluminescence

    The current study presents an emission spectroscopic investigation of clustered microflames established on a burner consisting of six micro fuel nozzles surrounding a center air nozzle which has been designed for flame synthesis and characterization of microflames. We conducted the spectrally resolved measurement of chemiluminescence of C2* and CH* and compared these results to a tomographic method applied to filtered emission measurements of CH* emission which can yield spatially resolved three dimensional mapping of the flame front. The analysis of the spatial distribution of the integrated band emission of C2* and the CH* showed that the emission of both species is generated in the same locations in the flame which are the thin flame sheets shown in the tomography results of CH*. The ratio of the C2* and the CH* emission from the emission spectroscopy measurements was used to determine a local corresponding equivalence ratio through empirically derived correlations for premixed flames reported in literature. The resulting equivalence ratio equals one when the flame zone established at the boundary between fuel and air, indicating that the diffusion dominated flame zones are established. Under certain nozzle pitch and flow rate conditions, the equivalence ratio above the center air nozzle inside the merged flame became significantly greater than one, which indicates a fuel rich premixed type flame zone being established.
    To determine distributions of rotational and vibrational temperatures throughout the entire flame, we used the spectrally resolved emission from C2* and CH*. The temperature associated with vibrational excitation was different for both species but remained constant throughout the entire flame region and was found no representation of the flame temperature but an artifact of the combustion reactions producing the chemiluminescence. The rotational temperature of di-atomic molecules, however, equilibrates rather quickly with the translational temperature and can accurately represent the gas-dynamic temperature of the flame. The temperature distributions found from the two species agreed qualitatively, the CH* temperature was consistently higher than the C2* temperature by about 200 K. Spatial resolution was assigned to the results from the spectroscopic measurements through a comparison with the tomographically analyzed images of the CH* chemiluminescence.

  • A Novel Rotational Internal Combustion Engine with a Single-Lobe Peritrochoid Rotor (Design Fundamentals and Motoring Test of a Prototype Engine)

    A novel rotational internal combustion engine is invented and investigated as an auxiliary power unit (APU) of aircraft and range extension power unit for electric automobiles. For the intended applications, IC engines are required to have vibration-free characteristics. There are no reciprocating components in the present engine, resulting in vibration-free operation. This engine mainly consists of a rotor casing, a rotor and a crankshaft. The rotor is shaped in a single-lobe peritrochoid (S.L.P.) curve. The rotor is turned using a crankshaft eccentricity e and self-rotation in the counter-direction is achieved using phasing gears. The rotor casing shape has two cavities that define the envelope curve of the rotating single-lobe peritrochoid rotor. The space between the rotor and casing is where the processes for the working gas are performed: intake, compression, ignition, expansion and exhaust. The intake of premixed air/fuel gas and exhaust of burnt gas are controlled by rotary valves installed on the combustion recesses of the rotor-casing. The combustion recesses are equipped with spark-electrodes for ignition. One of the advantages of this engine compared to Wankel rotary engines and a previous engine invented by authors is easy and reliable sealing of the working gas. In this engine configuration, a sealing component is only installed on the waist section of the rotor-casing, instead of complex sealing system used for the rotor in the case of Wankel engines, resulting in higher efficiency by reducing the leakage of working gas.
    In this paper, first the configuration and geometries of this engine are described. Next a prototype engine is introduced and the cyclic behavior of the working process of the engine is explained. The performance of the prototype engine driven by an electric motor is also shown.
