Aug. 22, 2023 Researchers show mechanics of how drag on a partially submerged object may be several times greater than drag on a fully submerged object made of the same ...
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 ...
July 11, 2023 An interdisciplinary team presents a study of the dynamics of buoyant spheres at the air-water interface. Their work reveals complex hydrodynamics involved in forming horizontal air cavities and the ...
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 ...
Apr. 6, 2022 A new laboratory 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 ...
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 ...
Sep. 22, 2023 There is a largely untapped energy source along the world's coastlines: the difference in salinity between seawater and freshwater. A new nanodevice can harness this difference to generate ...
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 ...
