Water & Dirt Management

Ensuring a vehicle’s performance under harsh weather conditions is crucial for customer satisfaction and driver safety. With the increase of sensors coming with ADAS requires sensors to have peak performance, even with these harsh conditions. This requires keeping sensors clear doing rain, snow, or dirt, whilst maintaining vehicle styling and budget for production. In addition to the sensors, windows/mirrors needs to keep clear for driver vision to the changing road conditions. Vehicle aerodynamic designers need to balance these objectives, between styling, acoustics, and water/dirt management while applying new innovative technologies.

Siemens PLM Software solutions enable you to develop a vehicle that performs in any weather condition to the standards you and your customers expect.

A complete understanding of how a vehicle interacts with water and dirt is an issue of safety, reliability and quality. It directly affects a driver when it’s most critical, such as in a rain storm on a highway at high speed. Drainage performance must ensure that water is cleared quickly and does not accumulate near electronic equipment, and that wading through puddles does not cause water ingestion by the engine intake system or damage underbody trays. The exploding integration of sensors coming with the rise of autonomous vehicles also adds a level of complexity, as keeping those sensors clean is essential to guarantee the expected level of performance and behavior. Car designs must be adapted integrating all these different factors, coming on top of classical attributes aerodynamicists have to study.

Siemens PLM Software solutions allow you to directly model these considerations with a complete 3D computational fluid dynamics (CFD) process that accounts for multiphase flows such as liquid films, sprays and deposition.
