Data-driven augmentation of a RANS turbulence model for transonic flow prediction

Purpose: This paper aims to improve Reynolds-averaged Navier Stokes (RANS) turbulence models using a data-driven approach based on machine learning (ML). A special focus is put on determining the optimal input features used for the ML model. Design/methodology/approach: The field inversion and machine learning (FIML) approach is applied to...

The hydro-mechanical interaction in novel polyurethane-bound pervious pavement by considering the saturation states in unbound granular base course

The pore-water pressure generated by intermittent dynamic vehicle loading under various saturation states is recognized as a critical factor influencing the behaviour of permeable pavement structures, especially the behaviour of UGB layer. However, the underlying mechanisms of hydro-mechanical interaction in the UGB layer and the influence on...

In-situ and numerical investigation on the dynamic response of unbounded granular material in permeable pavement

Permeable pavements have been widely used as an effective means to improve hydrological characteristics and the ecology of the urban environment. This study aims to investigate the response of fully permeable pavement (FPP) subjected to dynamic loading under dry and saturated conditions. A full-scale test track topped with polyurethane bound...

Full exploitation of high dimensionality in brain imaging: The JPND working group statement and findings

Advances in technology enable increasing amounts of data collection from individuals for biomedical research. Such technologies, for example, in genetics and medical imaging, have also led to important scientific discoveries about health and disease. The combination of multiple types of high-throughput data for complex analyses, however, has...

Gas turbine cycle calculations: experimental verification of off-design-point performance predictions for a two-spool turbojet with various air bleeds

As part of a continuing program of gas turbine cycle calculations , the Engine Laboratory of the National Research Council of Canada has proposed a simplified method for calculating off-design-point performance of turbojet and turbofan engines, both at sea level statie and at altitude flight conditions. This method specifically implies...

Ground effect experiments on a fan-in-wing configuration at zero forward speed

In order to investigate ground effect on a fan-in-wing configuration, a test rig was built. A 1-ft. diameter fan was buried in a 3-ft. by 5-ft. wing section. A movable ground board permitted operation at ground to fan-exit distances between 6 and 1/2 fan diameters. For one series, a symmetry wall was attached to one end of the aerofoil. Tip...
