Cambridge Professor's Door-Flapping Trick Cools Cars Instantly
Cambridge University professor Hannah Fry shares a fluid dynamics-based hack to cool down sweltering cars instantly. By opening one window and rapidly swinging the opposite door, drivers can expel hot air without using air conditioning. This method leverages the principles of bulk flow to replace hot interior air with cooler outside air.
Fry's technique involves opening a window on one side and fanning the opposite door to create airflow, effectively reducing interior temperatures. This approach, rooted in fluid dynamics, offers a quick solution during heatwaves, eliminating the need for air conditioning and providing immediate relief.
This door-flapping method has gained popularity, with many drivers adopting it as a quick and efficient way to cool their vehicles without relying on traditional air conditioning systems.
