LTRAC Laboratory for Turbulence Research in Aerospace and Combustion

The LTRAC Research Group at the Monash University undertakes world-leading research in the areas of turbulent flows, combustion, alternative and renewable energy, laser diagnostics and numerical simulation of turbulence. LTRAC has wide ranging capabilities in laser diagnostics including high resolution PIV, SPIV, Tomographic PIV (Tomo-PIV), Digital Holographic PIV, PLIF, Time-resolved PIV, SPIV and Tomo-PIV, high speed imaging including ultra-high-speed Schlieren capable of up to 1 Million frames per second imaging. First class Aerodynamics, Fluid Mechanics and constant volume combustion experimental facilities are available in the LTRAC laboratories. The group has substantial high performance compute facilities and data storage in-house in addition to access to all major University, State and National high performance computing facilities. The group has numerous links with both national and international research institutes, industries and universities.

LTRAC data from this collection includes:

Outputs from direct numerical turbulence simulations in format/s VTK, HDF5 and RAW with custom metadata. Much of this data is generated on EU PRACE and AU NCI supercomputing infrastructures and returned for analysis and future reference on smaller scale compute systems available locally. It is required to make much of this data available for reference with current and future publications, additionally some of this data is subject of active research and will require near-compute storage. Raw imaging data from planar, tomographic and holographic particle image velocimetery experiments with post processed results. The raw images are stored in the .b16 file format. Raw and processed data from particle tracking velocimetery experiments stored in HDF5 files. Raw images produced from high speed Schlieren experiments of supersonic flow phenomena.

本数据集收录的LTRAC相关数据包括：
1. 直接数值湍流模拟的输出结果，格式包含VTK、HDF5与RAW，并附带自定义元数据。其中多数数据依托欧洲PRACE与澳大利亚NCI超级计算基础设施生成，随后回传至本地小型计算系统供分析与后续留存。为支撑当前及未来的学术发表，该类数据的大部分将对外开放；此外部分数据属于活跃研究课题，需采用近计算存储方案。
2. 平面、层析与全息粒子图像测速实验的原始成像数据及后处理结果，原始图像以.b16文件格式存储。
3. 粒子跟踪测速（Particle Tracking Velocimetry, PTV）实验的原始与处理后数据，存储为HDF5文件格式。
4. 超声速流动现象高速纹影实验的原始成像数据。
