An aerodynamic CFD analysis of inlet swirl in a micro-gas turbine combustor

Author: Meyers, Bronwyn C ; Grobler, Jan-Hendrik ; Snedden, GC Date: Jul 2023 A combustor was designed for a 200N micro-gas turbine [1, 2] using the NREC preliminary combustor design method [1, 2, 3]. During the design process, there are various aspects where there are no definitive methodologies for specifying the ... Read more
The design and testing of a can-type combustor in a compressor test rig

Author: Meyers, Bronwyn C ; Jan, MA ; van der Spuy, SJ Date: Sep 2017 In order to increase the power of a blowdown, turbine driven compressor test rig, a combustor was designed to insert in the flow before the turbine. The combustor was required to provide 800K output temperature in order to achieve this. The ... Read more
Experimental results showing the internal three-component velocity field and outlet temperature contours for a model gas turbine combustor

Author: Meyers, BC ; Snedden, Glen C ; Meyers, Bronwyn C ; Roos, TH ; Mahmood, GI Date: Sep 2011 A three-component flow field inside a can-type, forward flow experimental combustor was measured under non-reacting conditions. The combustor was run at atmospheric conditions with the air flow supplied from a fan and the outlet was straight ... Read more
The numerical aerodynamic investigation of swirling inlet flow in a vaporizer tube micro-gas turbine combustor

Author: Meyers, Bronwyn C ; Grobler, Jan-Hendrik ; Snedden, GC Date: Sep 2022 A 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
Overview of experimental measurements in a generic can-type gas turbine combustor

Author: Meyers, BC ; Mahmood, GI ; Meyers, Bronwyn C Date: Nov 2009 Due to CFD Shortfalls, experimental data on gas turbine combustors is required to obtain insight into the combustion and flow mechanisms as well as for simulation and model validation and evaluation. The temperature and velocity fields of a ... Read more
The preliminary design of an annular combustor for a mini gas turbine

Author: Meyers, Bronwyn C Date: Oct 2015 This study involves the redesign of the combustor liner for a 200N mini gas turbine engine using first principles and the design methods of the NREC series as shown in Figure 1. The combustor design was performed using five different operating ... Read more
Three-component particle image velocimetry in a generic can-type gas turbine combustor

Author: Meyers, Bronwyn C ; Snedden, Glen C ; Meyer, JP ; Roos, TH ; Mahmood, GI Date: Nov 2012 A stereoscopic particle image velocimetry (PIV) system was used to obtain the velocity field of a can-type combustor in the non-reacting condition. In order for these measurements to be taken, an optically accessible can-type forward flow ... Read more
Three-dimensional particle image velocimetry in a generic can-type gas turbine combustor

Author: Meyers, BC ; Snedden, Glen C ; Meyers, Bronwyn C ; Roos, TH ; Mahmood, GI Date: Sep 2009 The three-dimensional flow field inside a generic can-type, forward flow, experimental combustor was measured. A stereoscopic Particle Image Velocimetry (PIV) system was used to obtain the flow field of the combustor in the non-reacting ... Read more
