Latest Patents

Ning Ren's latest patents include a "Method and system for spatially-resolved 3-dimensional characterization of near-field sprays." This invention establishes near-field spray characteristics through local measurements acquired by a data acquisition subsystem. The system utilizes different laser-based probes, such as shadowgraphy, PIV, and diffraction, to obtain measurements related to drops. A mechanical patternator measures the volume flux distribution of the spray under study. The data collected is post-processed to generate spatially-resolved spray characteristics mapped in a spherical coordinate system. This innovative approach also incorporates a data compression scheme to create compact analytical functions that can be utilized in computational fluid dynamics (CFD) based spray dispersion and fire suppression modeling.

Another notable patent is the "Method and system for evaluation of fire suppression systems performance." This invention fully characterizes the initial spray generated by a sprinkler using a laser-supported Shadowgraphy/PTV system. Similar to his previous work, near-field spray characteristics are established from local measurements and mapped in a spherical coordinate system. A novel data compression scheme is introduced to generate analytical functions that describe the sprinkler spray based on the measurements. These functions are essential for initiating the sprinkler spray in CFD-based spray dispersion and fire suppression modeling. The validation of the near-field spray measurements and the associated data compression approach is achieved by comparing volume density measurements with predictions generated from spray dispersion calculations.
