Niebuhr, Chantel Monica; Hill, Craig; Van Dijk, Marco; Smith, Lelanie (MDPI, 2022-07)Hydrokinetic turbine deployment in inland water reticulation systems such as irrigation canals has potential for future renewable energy development. Although research and development analysing the hydrodynamic effects of ...

Fouellefack, Lionel Dongmo; Smith, Lelanie; Kruger, Michael (Emerald, 2023-01)PURPOSE : A hybrid-electric unmanned aerial vehicle (HE-UAV) model has been developed to address the problem of low endurance of a small electric UAV. Electric-powered UAVs are not capable of achieving a high range and ...

Niebuhr, Chantel Monica; Van Dijk, Marco; Smith, Lelanie (Elsevier, 2023-10)Hydrokinetic (HK) energy production has been primarily developed for use in tidal energy applications. However, where inland water infrastructure systems with sufficient velocities and spatial requirements exist, HK energy ...

Schoombie, Janine; Schoombie, S.; Connan, Maelle; Jones, C.W.; Risi, M.; Craig, K.J. (Kenneth); Smith, Lelanie; Ryan, P.G.; Shepard, E.L.C. (Inter Research, 2023-11)Albatrosses exploit winds to travel vast distances across the ocean. Their morphology is adapted for low-cost dynamic soaring flight, but these adaptations confer low manoeuvrability, which may be risky when flying over ...

Smith, Lelanie; Oxtoby, Oliver F.; Malan, A.G.; Meyer, Josua P. (Emerald, 2013)PURPOSE – The purpose of this paper is to introduce a unique technique to couple the two-integral boundary layer solutions to a generic inviscid solver in an iterative fashion. DESIGN/METHODOLOGY/APPROACH – The boundary ...

Smith, Lelanie; Craig, K.J. (Kenneth); Meyer, Josua P.; Spedding, G.R. (American Institute of Aeronautics and Astronautics, 2019-01)It is common for new aircraft configuration proposals to include some kind of lifting body. The reduction in fuselage–wing interference drag, in principle, improves span efficiency and hence allows for reduction in total ...
-
Tank, J.; Smith, Lelanie; Spedding, G.R. (The Royal Society, 2017-02)The flight of many birds and bats, and their robotic counterparts, occurs over a range of chord-based Reynolds numbers from 1 x 104 to 1.5 x 105. It is precisely over this range where the aerodynamics of simple, rigid, ...

Mutangara, Ngonidzashe E.; Smith, Lelanie; Craig, K.J. (Kenneth); Sanders, Drewan S. (American Institute of Aeronautics and Astronautics, 2021-11)New aircraft developments are made to improve aircraft performance and efficiency. One such method is integrating propulsion into the airframe. This allows for boundary-layer ingestion, which shows promise of significant ...

Matemba, Esther; Smith, Lelanie; Inglis, Helen Mary; Mogashana, Disaapele; Jansen, Lauren; Gwynne-Evans, Alison; Campbell, Anita L.; Kwuimy, Cedrick; Nassar, Shamim; Magara, Irene; Kloot, Bruce; Hattingh, Teresa; Raji, Atanda; Musa, Tagwa; Nyamapfene, Abel (Taylor and Francis, 2023)The Engineering Education Research Network in Africa (EERN-Africa) was created to enable connections between practitioners and researchers with a shared interest in African engineering education contexts. Recognising the ...

Niebuhr, Chantel Monica; Schmidt, S.; Van Dijk, Marco; Smith, Lelanie; Neary, Vincent S. (Elsevier, 2022-04)Computational fluid dynamics is employed for detailed prediction of the hydrokinetic turbine performance and wake modelling. Of these, Reynolds-averaged Navier-Stokes (RANS) models are most widely used due to their ability ...
