"FlowExpert2D3C" is a fluid analysis software that extracts the three components of velocity by analyzing images taken synchronously with two cameras on a two-dimensional cross-section visualized with a laser sheet. By adding depth direction evaluation, it achieves high-precision analysis for phenomena where accurate flow evaluation was difficult with two-component assessment. Additionally, it is compatible with time-series PIV using two high-speed cameras as well as those using a W-pulse light source. [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.
