    Non-scanning 3D-CT(Computer Tomography) technique employing a multi-directional quantitative schlieren photographic system with flash light source, has been performed to obtain instantaneous density distributions of spark-ignited laminar / turbulent flame kernels. For simultaneous schlieren photography, the custom-made 20-directional schlieren camera was constructed and used. The flame kernels are made by spark ignition for a fuel-rich propane-air premixed gas (flow velocity :1.0 m/s, equivalence ratio :1.4 ). Spark electrodes of 0.4 mm diameter with 1.0 mm gap are used. First, development of laminar flame kernel is indicated in the 1st row high-speed image of top right. 3D printed model of the CT reconstruction result show the spherical shape of flame kernel with a pair of deep wrinkles. The wrinkle is considered to be caused by spark electrodes. Next turbulent flame kernel behind turbulence promoting grid is selected (trubulence intensity 0.26 m/s). Second row high-speed images of top-right show corrugated flame shape. 3D model of CT result expresses the instantaneous 3D turbulent flame kernel shapes. These 3D solid models are 3D-printed as 2 times large size for threshold density level of 0.7 kg/m3.

    Measurement of instantaneous density distribution of the shock-cell structure of an underexpanded supersonic microjet escaping into an ambient space from an axisymmetric convergent-divergent (Laval) micro nozzle has been conducted. For 3D observation of supersonic microjet, non-scanning 3D-CT technique using a multi-directional quantitative schlieren system with flash light source is employed. In this technique, for simultaneous schlieren photography, the custom-made 20-directional schlieren camera has been constructed and used. This study examines underexpanded supersonic jet from a micro nozzle with nozzle pressure ratio (NPR) 5.0 and plenum chamber pressure (stagnation pressure) 0.505 MPa. This micro nozzle design Mach number is Md = 1.5 and has circular cross-section with an exit diameter of 1000μm. First, the report deals with the density distribution. The density contour plot data of the jet flow is obtained by 3D-CT (Three Dimensional Computer Tomography) reconstruction of the images by MLEM an appropriate CT algorithm. Next, the density distribution data is calculated by formula. Theoretical results based on the theory of Tam (1984) are found to compare favorably with experimental measurement. The measured and calculated results are in acceptable agreement.
