"FlowExpert2D3C" is a fluid analysis software that extracts three velocity components by analyzing images taken synchronously with two cameras on a two-dimensional cross-section visualized with a laser sheet. By adding depth direction evaluation to phenomena where accurate flow assessment was difficult with two-component evaluation, it achieves high-precision analysis. Additionally, it is compatible with time-series PIV using two high-speed cameras as well as systems that utilize W-pulse light sources. [Analysis Images] - Instantaneous velocity vectors - Misalignment correction - Vorticity - Average velocity vectors - Turbulent energy, etc. *For more details, please download the PDF or feel free to contact us.

The "SS Series" is a system-type Schlieren that visualizes even subtle differences in density gradients with low refractive index at a high level, using a W-path method where parallel light passes through the observation space twice. The optical axis adjustment has been simplified, making Schlieren photography easy and accessible. Additionally, it achieves less than half the space requirement of conventional systems, alleviating concerns about space. 【Features】 ■ Capable of visualizing subtle differences in density gradients with low refractive index at a high level ■ Simplified optical axis adjustment allows for easy Schlieren photography ■ Can be installed in less than half the space of conventional systems ■ The optical system that determines the observation space is adjustable via a sliding mechanism ■ Can be detached from the main unit for installation (optional) *For more details, please download the PDF or feel free to contact us.
