Experimental and numerical investigations in the near-burner region of a versatile multi-fuel burner
An experimental and numerical investigation on the effect of swirl on the motion of coal particles in the near-burner region of a versatile multi-fuel swirl-stabilised laboratory burner of total thermal input of 100kW, has been performed. The burner was designed as a scale model of a lOMW coal burner operating in a cement rotary kiln, produces flames of different aerodynamic characteristics, an...
متن کاملNumerical Simulations of Isothermal Flow in a Swirl Burner
In this paper, the non-reacting flow in a swirl burner is studied using large eddy simulation. The configuration consists of two unconfined coannular jets at a Reynolds number of 81,500. The flow is characterized by a Swirl number of 0.93. Two cases are studied in the paper differing with respect to the axial location of the inner pilot jet. It was observed in a companion experiment (Bender and...
متن کاملSimulation of Cup-Burner Flames in Microgravity
The extinction process of cup-burner flames under normal-gravity conditions were previously studied. As the low-speed diffusion flames behave differently in microgravity compared to those on earth, it is important to understand the structure of cup-burner flame and its extinction characteristics under 0g conditions. A numerical study was performed in the present paper using a time-dependent, ax...
متن کاملNumerical Investigations of Chemical Kinetics for Methane Catalysis and Pyrolysis
In the framework of the active and regenerative cooling of hypersonic and space structures, a kinetic mechanism should be proposed to investigate numerically the fuel pyrolysis and the coke formation with a possible surface effect (catalytic reactions). This chemical mechanism should be suitable for Computational Fluid Dynamics approach (limited number of species and reaction). For this purpose...
متن کاملNumerical investigations on the stability of flame balls
The paper is concerned with the numerical simulation of two– and three–dimensional flame balls. In the two–dimensional case we use a Galerkin–type discretization in an adaptive basis of orthogonal wavelets. Therewith the solution is represented by means of a reduced basis being adapted in each time step. For the three–dimensional simulations we employ a classical Fourier pseudospectral method i...
