Turbulent flows show a non-linear behaviour and can in most cases be investigated experimentally or numerically only at high costs. For the last two decades one of the most important challenges in this field have been control and optimization of fluid flows with the goal to decrease flow resistance, to reduce the flow noise of vehicles and machines, and to improve mixing (e.g. in combustion chambers).

湍流表现出一种非线性行为，在大多数情况下，只能以高昂的成本进行实验或数值研究。在过去的二十年里，该领域最重要的挑战之一是控制和优化流体流动，以降低流动阻力，降低车辆和机器的流动噪声，并改善混合(例如在燃烧室中)。
