Purpose and goal
The objective of this project is to create the prerequisites to, in early phases of a vehicle development project, by means of simulations, be able to virtually assess suitable placements of sensors for autonomous drive and active safety systems on the exterior body of a vehicle when the vehicle is used in a realistic user environment, i.e. in rain or on wet roads. If exterior sensors become wet or contaminated, the automated systems relying on the sensor input will be impaired, or in a worst-case scenario, fail to work altogether.
Expected results and effects
The project will result in the following: 1. Numerical models describing water movement on a rotating front wheel, taking into account wheel modelling technique and water dynamics 2. Robustness and sensitivity analysis of the numerical models to ensure that the models are valid under real-life conditions. 3. Detailed information on spray characteristics in the vicinity of the front wheel. 4. Numerical models replicating the spray characteristics. 5. Choice of a phase-coupling formulation that is needed to capture the interaction between water and air.
Planned approach and implementation
The project will be conducted using a combination of experimental work, numerical modelling and numerical simulations. The first part of the project will be focused on experimental work, as these activities will build a foundation for development of numerical models, simulations and validation of the numerical models. In all phases of the project, full scale production vehicles and/or wheels will be used.
