Implementation of a Combustion Module within the Nektar++ FrameworkCombustion modelling methods are implemented into the Nektar++ framework to create a reactive flow solver capable of accurately modelling combustion flow regimes at low Mach numbers. The study investigates how the high-order resolution of a mixing flow field translates to modelling of ...

SummaryTwo methods of analysis are developed for the unsteady wave flow through axial turbomachinery of high hub-tip ratio. In the first method, the machine is supposed to consist of an infinite number of small stages. Differential equations for the instantaneous values of flow properties are derived which may be solved directly or by the method of ...
