Abstract

A multi-component All-Mach solver is developed at the Laboratorio de Mecânica dos Fluidos (MFLab) in the Multi-Physics Simulator (MFSim) environment. The code uses a finite volume scheme featuring total variation diminishing (TVD) discretization methods, immersed boundary method (IBM), and SIMPLE family algorithm, such as Semi-Implicit Method for Pressure-Linked Equations (SIMPLE), Semi-Implicit Method for Pressure Linked Equations-Consistent (SIMPLEC) and Pressure-Implicit with Splitting of Operators (PISO). The code is used to study a non-reactive Volvo burner case with a bluff-body. The case assessed in the present work was studied experimentally in the Volvo Flygmotor AB program, the experimental results of the non-reactive case are compared with the results obtained by MFSim. The simulations are performed using a propane gas mixture, with their properties being evaluated through the CANTERA software. RANS and Large Eddy Simulation (LES) and the All-Mach PISO algorithm. The results agree with the experimental data.
