“…Combined application of PLIF imaging and PIV has been used extensively in recent years in a variety of nonpremixed [114][115][116][117][118], lifted partially-premixed [119][120][121], and premixed [45][46][47][48] turbulent flames. These measurements have been enabled by the development of digital PIV, which has in turn been enabled by the introduction of large interline-transfer arrays (e.g., 2048 · 2048 pixels and, more recently, 4008 · 2672 pixels).…”

“…First, the use of simultaneous techniques, in one or multiple interrogation planes, allows for measuring several flow field properties, for instance, multiple scalar fields and temperature [46] or velocity [27,36,44]. Multi-scalar fields have been measured in 2D [36] and also in 3D [44], simultaneously with the velocity field, both in low temporal resolution.…”

With the developments of computer technologies, three-dimensional direct numerical simulations (DNS) of turbulent combustion have been realized with a detailed or reduced kinetic mechanism. The 3D DNS gives detailed information about turbulent flames, while there are few experimental techniques which have high accuracy enough to compare with DNS. In this paper, after showing summary of recent DNS of turbulent premixed flames, newly-developed laser diagnostics are presented. Simultaneous CH-OH planar laser induced fluorescence (PLIF) and stereoscopic particle image velocimetry (PIV) are used to investigate the local flame structure of the turbulent premixed flames. From CH-OH PLIF and PIV measurements, flame fronts are identified, and the curvature of the flame front and the tangential strain rate at the flame front are evaluated. The experimental results are compared with 3D DNS of hydrogen-air and methane-air turbulent premixed flames. The flame displacement speeds in turbulent premixed flames have been measured directly by the CH double-pulsed PLIF. Since the time interval of the successive CH PLIF can be selected arbitrarily, both of the large scale dynamics and local displacement of the flame front can be obtained. As an application of laser diagnostics for development of high-efficient and low-emission combustors, reconstruction of 3D flame structure is shown by using multiple-plane OH PLIF.
