Author:Meyers, Bronwyn C; Grobler, Jan-Hendrik; Snedden, GCDate:Sep 2022A combustor was designed for a 200N micro-gas turbine for the model aircraft industry using the NREC design method. Multiple designs resulted which varied in terms of annular area split configuration, hole area splits and relative hole ...Read more
Author:Gledhill, Irvy MA; Roohani, H; Forsberg, K; Eliasson, P; Skews, BW; Nordström, JDate:Feb 2016Most computational fluid dynamics simulations are, at present, performed in a body-fixed frame, for aeronautical purposes. With the advent of sharp manoeuvre, which may lead to transient effects originating in the acceleration of the centre ...Read morecb
Author:Ndebele, Bright B; Gledhill, IMADate:Sep 2023The dynamics of two-dimensional vortex shedding from a rotating cluster of three cylinders was investigated using Computational Fluid Dynamics (CFD) and Dynamic Mode Decomposition (DMD). The cluster was formed from three circles with equal ...Read more
