Background-oriented schlieren tomography is a prevalent method for visualizing intricate turbulent flows, appreciated its ease of implementation and ability to capture three-dimensional distributions multitude flow parameters. However, the voxel-based meshing scheme leads significant challenges, such as inadequate spatial resolution, substantial discretization errors, poor noise immunity, excessive computational costs. This study presents an innovative reconstruction approach termed neural...
A single-shot, lifetime-based pressure-sensitive paint (PSP) technique is proposed as a pressure sensor for applications requiring high sensitivity on moving model such rotor blade. The method based single pulse of high-energy excitation light and double-frame exposure an interline transfer charge-coupled device camera recording luminescent lifetime. Small pressures can be measured surfaces that are in aperiodic manner (which precludes phase averaging). Measurements environments having...
This paper describes the development of a two-color fast-responding pressure-sensitive paint with temperature correction capability. uses platinum porphyrin compound as pressure sensor perylene reference and laser dye added to adjust spectrum distribution sensitivity channel. Separate emission signals sensors can be captured by red green channels color camera, respectively. Temperature errors are counteracted taking ratio ratios, whereas parameter is introduced compensate for difference in...
Unsteady pressure-sensitive paint (PSP) measurements were acquired on an articulated model helicopter rotor of 0.26 m diameter in edgewise flow to simulate forward flight conditions. The was operated at advance ratios (free stream velocity normalized by hover tip speed) 0.15 and 0.30 a cycle-averaged chord Reynolds number 1.1 × 105, with collective longitudinal cyclic pitch inputs 10° 2.5°, respectively. A single-shot data acquisition technique allowed camera record the luminescence after...
The spatiotemporal distributions of the coolant coverage behind 777-shaped hole, sweeping jet (SJ), and compact SJ were quantified comprehensively. Nitrogen gas was selected as coolant, its blowing ratio (M) set from M = 1.0 to 3.0. fast pressure-sensitive paint technique applied measure instantaneous, mean, unsteady film cooling effectiveness three configurations, these data are compared side-by-side with hole. measured velocity spectra demonstrated a close level Strouhal number for (St...
The genus Salvia L. (Lamiaceae) comprises myriad distinct medicinal herbs, with terpenoids as one of their major active chemical groups. Abietane-type diterpenoids (ATDs), such tanshinones and carnosic acids, are specific to exhibit taxonomic diversity among lineages. To elucidate how ATD evolved, we carried out large-scale metabolic phylogenetic analyses 71 species, combined enzyme function, ancestral sequence trait reconstruction, comparative genomics experiments. This integrated approach...
Abstract This paper introduces a high-precision and nearly single-pixel three-dimensional (3D) calibration framework for the camera system optical transfer function (OTF); using digital micromirror device (DMD) to generate large number of 3D points, precise reconstruction 2D reprojection particle-based velocimetry techniques is achieved. Additionally, line-of-sight (LOS) approach, which utilizes an extensive LOSs from points centers, leverages accurate reconstruction—even in presence curved...
A phosphorescence-based flexible optical temperature-sensing skin was developed for temperature sensing in intelligent bionic robots and automated medical treatment. 4,4-Diamino diphenyl ether 4,4′-oxydiphthalic anhydride were combined as polyimide use the substrate of sensor.

Ultrasonic dispersion thermal imidization used to prepare a 45-μm-thick Compared traditional electronic-based sensor, sensor has advantages noncontact measurement, wide range...
Vortex dynamics during parallel blade-vortex interactions (BVIs) were investigated in a subsonic wind tunnel using particle image velocimetry (PIV). Vortices generated by applying rapid pitch-up motion to an airfoil through pneumatic system, and the subsequent with downstream, unloaded target studied. The may be classified into three categories terms of vortex behavior: close interaction, very collision. For each type trajectory strength variation obtained from phase-averaged PIV data....
A data-fusion approach is reported to reconstruct missing data and applied particle image velocimetry (PIV) measurements. This departs from the existing ones in that datasets involved its operation are incomplete. Two sets of incomplete but complementary with fault regions, obtained using different measurement setups, combined yield a complete dataset by reconstructing data. In this report, capability current first demonstrated three fabricated scalar patterns frequency spectra. Second,...
