Full description
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.
Significance Statement
The modelling work of the LTRAC group has attracted significant national investment through ARC funding and existing national computational MACs, in addition the LTRAC’s work is supported through the EU’s PRACE scheme. Significant quantities of simulation trace data are collected from LTRAC’s modelling, this data is a direct input into existing and future research outputs and requires storage for both preservation and future analysis. The detailed information obtained from the above simulations and the following analyses will assist in the development of realistic physical models that explain the complex mechanics and phenomena associated with turbulent shear flows and under-expanded supersonic impinging jet flows. These include the instability and transition to turbulence, formation of coherent flow structures, vortex breakdown and importantly the control of these phenomena. Thus, a better understanding of the complicated turbulent flow physics leads to significantly optimised engineering designs in aviation, transportation, and power generation to reduce energy consumption and consequently to diminish carbon dioxide emissions.
