MATHEMATICAL MODELLING OF 3D FLUID FLOW AROUND BLUFF BODIES

Objective


IKARUS code developed as a solver for the Navier-Stokes equation for three-dimensional separated flow around bluff bodies and is suitable for applications for car industry. It includes major improvements currently available for the numerical simulation of industrial problems.

Two types of models were developed to provide data and evaluate IKARUS, the split sphere model and JRC R25, a modification of the Renault 25.

IKARUS correctly calculates the larger structures of the flow around bluff bodies with wall pressures and visualizations in agreement with experiments. But the two equation turbulence models currently available do not fully simulate base flows when they are strongly three-dimensional.
ACCURATE COMPUTATION OF DRAG AND LIFT OF BLUFF BODIES AT HIGH REYNOLDS NUMBERS NEEDS AN ACCURATE NUMERICAL EVALUATION OF THE TURBULENT BOUNDARY LAYER GROWTH, OF ITS SEPARATION, AND OF THE VORTEX SHEDDING AND TRACKING. FOLLOWING THE CONCLUSION OF THE PHASE 1 OF THE PROJECT AND THE MID-TERM ASSESSMENT EVALUATION, IT APPEARS THAT THE KEY POINT FOR THESE PREDICTIONS IS THE MODELLING OF TURBULENCE.

THE ULTIMATE OBJECTIVES OF THE PHASE 2 ARE
(1) INTEGRATION OF THE ALGORITHMS DEVELOPED DURING THE PHASE 1 IN A CODE INCLUDING ALL IMPROVEMENTS, MAINLY IN BOUNDARY LAYER CALCULATION, LOCAL GRID REFINEMENT, VORTEX SHEDDING AND TURBULENCE MODELLING.
(2) DEVELOPMENT OF AN INDUSTRIAL NAVIER-STOKES COMPUTER PACKAGE USABLE AS A TOOL FOR DESIGNERS AND CAPABLE OF PREDICTING COMPLETE FLOW FIELDS AROUND A COMPLETE CAR.
(3) VALIDATION OF THE CODE USING A REALISTIC FULL SCALE SMOOTHED CAR SHAPE.
