Mar. 8, 2023 —Ships are the main modes of transport for global trade as they are efficient and effective. Improving the aerodynamic performance of ship could reduce fuel consumption and improve speed, further ...
Jan. 18, 2022 —Tiny gas bubbles could help reduce drag in small medical devices, scientists have found. Drag can lead to clogging and damage biological samples, so this discovery could pave the way to more robust ...
Apr. 4, 2023 —A research team has demonstrated a unique method that reduces the aerodynamic resistance of ships by 7.5 per cent. This opens the way for large cargo ships borne across the oceans by wind alone, as ...
Sep. 15, 2020 —Fish and seaweed secrete a layer of mucus to create a slippery surface, reducing their friction as they travel through water. A potential way to mimic this is by creating lubricant-infused surfaces ...
Apr. 6, 2022 —一个新的拉boratory method uses a high-accuracy ball delivery device and speed measurement system to provide better clues on exactly how high and far some of those baseballs will ...
Feb. 2, 2023 —Sometimes, the most complex problems can be solved with the simplest approaches. Such was the case for researchers as they tried to resolve a longstanding issue of fluid friction -- the resistance ...
Oct. 7, 2020 —A new research study has revealed that fish scale arrays generate a streaky base flow on the surface of the animal which yields important clues into reducing drag - the aerodynamic force that opposes ...
Apr. 20, 2021 —To search for answers about how blood droplets from a gunshot wound can reverse direction while in flight, researchers explored the influence of propellant gases on blood backspatter. They report ...
June 16, 2021 —We've seen robots take to the air, dive beneath the waves and perform all sorts of maneuvers on land. Now, researchers are exploring a new frontier: the ground beneath our feet. Taking their ...
Aug. 31, 2021 —Researchers detail how the protruding eyes and mouths on simulated stingrays affect a range of forces involved in propulsion, such as pressure and vorticity. They created a computer model of a ...
