Question

Identify some examples of streamline flow and turbulent flow in every day life. How would you explain them? When would your prefer a stream line flow?

Answer 1

Examples of streamlined flow include smoke rising from an incense stick in a windless room and airflow around a moving automobile or plane. Additionally, fish, dolphins, and whales have streamlined shapes to reduce drag. Long-distance migratory birds often have long necks, and flocks fly in a spearhead shape to create a streamlined pattern.

Turbulence leads to wasted energy. Aeroplanes and cars are designed to minimise fuel consumption by reducing friction. Turbulence is frequently observed in washing machines and kitchen mixers. Turbulence in these devices is beneficial since it promotes mixing.

High-speed videography and computational modelling are improving our understanding of the aerodynamics of bird and insect flight, a topic of interest for physicists and biologists alike.
