Propeller cavitation
Propeller cavitation. Test being carried out on a propeller to study cavitation effects. Cavitation is the formation of bubbles in a liquid due to changes in pressure, as happens in water being churned by a propeller. Studies of cavitation aim to improve propeller design to reduce the turbulence caused by this unwanted effect. Photographed in the Ship Division of the National Physical Laboratory, Teddington, UK.

EDITORS COMMENTS
This print captures a momentous test being conducted on a propeller to study the intriguing phenomenon of propeller cavitation. The image was taken at the Ship Division of the renowned National Physical Laboratory in Teddington, UK. Cavitation occurs when changes in pressure cause bubbles to form in a liquid, such as water being churned by a propeller. This unwanted effect leads to turbulence, which can hinder propeller efficiency and performance. In this historical snapshot, we witness scientists engrossed in their research and experimentation, aiming to enhance propeller design by reducing the turbulent wake caused by cavitation. The smooth rotation of the model propeller creates an intricate pattern within the liquid medium, showcasing the complexity of fluid dynamics. This photograph not only highlights technological advancements but also reflects upon England's rich maritime history and its contributions to engineering excellence. It serves as a testament to British ingenuity during the 20th century. As we delve into this mesmerizing image captured by Science Photo Library, we are transported back in time to witness pioneering efforts aimed at analyzing and understanding cavitation effects. Through meticulous testing and analysis carried out at NPL's laboratory, researchers strive towards improving transportation systems through more efficient propellers that minimize turbulence caused by this fascinating yet challenging phenomenon.
