DaimlerChrysler is developing new ways of creating computer models that will allow its designers to optimise airflow through vehicle ventilation and climate control systems, writes Jonathan Thomson.

Researchers at the company’s laboratory for acoustics and climate control told just-auto.com that ventilation channels normally “snake their way around many corners” on the way from the engine to the interior, creating high resistance to the airflow.

Instead of using time-consuming numerical calculations to improve airflow, the laboratory said it had developed a faster method, which it calls “bionic optimisation”.

Researcher Franz Klimetzek said it now takes them “only a few hours” to design a low-loss airflow channel within the space available – a process that can take several days, even when using powerful computer systems.

While Mr Klimetzek would not reveal much about the new technique, he did explain: “The process is based on the fact that the airflow will always seek out the best route for itself.”
