Abstract

This training session aims at learning the participants the basics of combustion instabilities as well as how to use the thermoacoustic code AVSP developed at CERFACS. The latter is a general purpose Helmholtz solver which computes the frequency of oscillation, growth rate and spatial structure of the thermoacoutic modes of interest. Several test cases are considered during this one day training session in order to get the participants acquainted with the different features of AVSP (speed of sound inhomogeneities, complex valued boundary impedance, multi-perforated liners, acoustic flame coupling, multi-burner annular combustors, …).

Target participants

This training session is for engineers, physicists, computer scientists and numerical analysts who wish to learn on thermoacoustic instabilities.

Prerequisites

Unix, Fortran, numerical simulation.

This study focuses on Hall-effect thrusters, which were first invented in the 1960s. Although such systems have been extensively studied, the detailed physics of the magnetized plasmas in these thrusters is very complex and several plasma processes that have direct influence on the thruster...Read more
