The Poiseuille flow serves as an important benchmark for the validation of CFD methods as well as for studying fundamental aspects of pressure-induced incompressible internal flows. In this article, capabilities of PreonLab in capturing hydrodynamically fully developed 2-D laminar flows between parallel plates (known as planar Poiseuille flow) are evaluated for different Reynolds numbers.

The lid-driven cavity problem is of high importance in fluid dynamics serving as a benchmark for the validation of CFD methods as well as for studying fundamental aspects of incompressible flows in confined volumes driven by the tangential motion of one or more bounding walls. In this article, capabilities of PreonLab in capturing 2-D flows inside a cavity are evaluated for different Reynolds numbers.

For coarsely-resolved simulations, especially those for applications that require numerous quick design iterations to asses the plausibility of a design, a simulation that both runs quickly and delivers results in the correct ballpark is needed. The coarse resolution allows for fast computation, but such simulations tend to suffer from gradient underprediction at the walls. This happens in particular for flow regimes which may be considered as turbulent, where the steep gradients at the wall mean that a very fine resolution is required to correctly reproduce them. With the effect of wall-bounded phenomena (e.g. wall shear stress, wall heat flux) being a key result for studies that such simulations are used for, it is clear that there is potential for improvement here.

The automotive world is changing. In order to keep up with the challenges faced in the context of digitalization, Audi established the simulation of water in the development process. In the beginning of this century the Audi portfolio had five segments with different models. From year to year, new model lines were added to meet growing customer needs. Currently, the automotive industry is faced with new challenges in fulfilling the criteria for sustainability and climate neutrality, resulting in even more models with various new types of powertrains, such as hybrid or the e-tron.

PreonLab is successfully employed by Renault to validate and improve heat shield designs which guarantee that no flammable liquid gets in contact with hot parts of the engine. Testing on a real prototype is difficult since first the leakage itself has to be reproduced and secondly, hot liquids may be dangerous.

Thanks to the electrification of the powertrain, innovation in the automotive industry is happening faster than ever. Short time to market for electric vehicles (EVs) and hybrid vehicles (HEVs) is one key to be successful for OEMs and tier 1 suppliers.

These are challenging and exciting times for the automotive industry. In 2020 the current EU regulations that set CO2 emissions standards for cars and vans will be replaced with stricter targets to be met by 2025, so innovative solutions are necessary to secure high mobility comfort at low emission rates. Our customer Volvo Car Corporation aims to have 50% of their annual sales come from fully electric vehicles.
