Data Brief

POLO Research Laboratories for Emerging Technologies in Cooling and Thermophysics, Federal University of Santa Catarina, CEP 88040-900, Florianopolis, SC, Brazil.

Published: April 2020

The data presented herein are related to the simulations and correlations reported in the article entitled "Numerical analysis and correlations for radial and tangential leakage of gas in scroll compressors" [1]. The numerical simulations were carried out using the ANSYS FLUENT 12.1.4 CFD code, which is based on the finite volume method. Details of the numerical modeling setup and data collection are provided to allow reproducibility. The datasets include predicted values of radial and tangential leakage carried out using ANSYS FLUENT 12.1.4 CFD code for different gases, operating conditions and geometries expressed as dimensionless parameters. The scripts in C++ for the correlations of radial and tangential leakages developed based on the numerical predictions are also provided together with experimental and numerical data used to validate the correlations.

The traditional phase shift measurement technique necessitates two orthogonally oriented fringe patterns to complete the phase measurement, which is time-consuming, and the phase modulation of the traditional fringe image exhibits only a gradient change in a single direction of the horizontal-vertical fringes, or a smooth gradient change in the tangential direction of the circular fringes. To enhance the measurement speed and improve the adaptability to large curvature measured specular surfaces, this paper proposes a phase measurement deflectometry (PMD) technique based on composite circular fringes. The composite circular fringes demonstrate a steeper slope in the phase change, enabling the acquisition of finer surface features under identical measurement conditions, effectively improving the detection sensitivity to small shape changes and enhancing the ability to discern fine details.

Based on the symmetric initiation mechanism of double-wing cracks in coal rock mass induced by high-pressure electro-recoil water pressure, fracturing experiments have been performed on coal rock mass under different water pressures and discharge conditions using high-voltage electric pulse hydraulic fracturing devices. Combined with CT scans, the crack spatial distribution inside the post-break coal rock mass was analyzed and found that the edge of the water injection hole is prone to produce double-wing cracks along the drilling hole diameter. ABAQUS is used to verify the physical test and extend the test conditions, the geometric parameter change, morphological expansion rule and crack initiation mechanism of double-wing crack in coal rock mass under different discharge conditions and ground stress conditions are studied.

Tire wear particles (TWPs) are generated with every rotation of the tire. However, obtaining TWPs under real driving conditions and revealing key factors affecting TWPs are challenging. In this study, we obtained a TWPs dataset by simulating tire wear process under real driving conditions using a tire wear simulator and custom-designed test conditions.

This study investigates lignin's influence on the hygroscopic behavior of poplar wood. Delignification was achieved using an acidic NaClO solution, and digital image correlation (DIC) was employed to measure strain distribution during shrinking and swelling across relative humidity (RH) ranging of 0 % to 97 %. Results showed that lignin removal increased equilibrium moisture content (EMC) by up to 3.
