This project aims to develop optimised surfaces which minimise the drag experienced by a body rolling on a wall in a fluid. The force applied to the body by the surrounding fluid exhibits a surprising dependence on surface texture, which is not well understood. This project will develop innovative new models to understand how the details of surface texture, such as the size, shape and distribution of roughness elements, influence the fluid forces and subsequent motion of the body. These models will be used to develop optimal surface textures to minimise drag. The benefits of this project include substantially improved modelling of sediment transport in industrial and natural flows, and significant reduction of friction in roller bearings.","funding-current":442684.00,"funding-at-announcement":439243,"investigators-current":[{"title":"Dr","firstName":"Stephen","familyName":"Terrington","roleName":"Discovery Early Career Researcher Award","roleCode":"DECRA","isFellowship":true,"orcidIdentifier":"0000-0001-9117-9170 "}],"investigators-at-announcement":[{"title":"Dr","firstName":"Stephen","familyName":"Terrington","roleName":"Discovery Early Career Researcher Award","roleCode":"DECRA","isFellowship":true,"orcidIdentifier":"0000-0001-9117-9170 "}],"organisations-current":[{"organisationName":"Monash University","roleName":"Administering Organisation","state":"VIC"}],"organisations-at-announcement":[{"organisationName":"Monash University","roleName":"Administering Organisation","state":"VIC"}],"field-of-research":[{"isPrimary":true,"code":"4012","name":"Fluid Mechanics and Thermal Engineering","type":"FOR20"},{"isPrimary":false,"code":"401204","name":"Computational Methods In Fluid Flow, Heat and Mass Transfer (Incl.

While surface roughness is known to substantially affect the fluid forces acting on a particle in contact with a wall, the details of this process are not known. This project will develop new models to explain how the details of surface texture affect the drag for a particle in contact with a wall, and develop optimised surfaces to minimise drag. This project will lead to substantial economic and environmental benefits to Australia. Industrially, it will lead to improved design and efficiency of many processes featuring particle-laden flows, such as fluidisation and sedimentation. Environmentally, it will lead to improved modelling of sediment transport in rivers and coastlines. It will also inform the design of low-friction surfaces for use in roller bearings, with significant economic benefits in reducing frictional loss and extending useful life. Finally, the project will increase Australia’s capabilities and expertise by training PhD and honours researchers in experimental and computational fluid dynamics. The findings will be shared with industry and the broader scientific community through open access publications and conference presentations, and directly with the numerous Australian industry partners with which the host team has strong and continuing working partnerships."}}}
