TL;DR: In this article, a modified test rig has been developed from the former Cardiff University ‘Cloud Chamber’ for this experimental study, which comprises of a 250-mm length cylindrical stainless steel explosion bomb enclosed at one end with a stainless steel plug which houses an internal stirrer to allow mixing.

TL;DR: In this article, the numerical simulation of a turbulent non-premixed hydrogen (H 2 ) diffusion flame has been performed in a model combustor, where air 25% was staged and introduced through the two tangential inlets.

TL;DR: In this paper, a three-dimensional micro combustor model was built to investigate impact of various turbulence models on combustion and emission behavior of studied hydrogen/air flames, and performance evaluation of these models was executed by examining combustor outer wall temperature distribution; combustor centerline temperature, velocity, pressure, species and NOx profiles.

TL;DR: In this paper, the effect of hydrogen addition on combustion instability was assessed by examining the flame response to a range of constant amplitude, single frequency chamber acoustic modes, and it was found that the flame shows significant increases in flame base coupling and flame compaction with increasing hydrogen concentration for all conditions.

TL;DR: In this paper, the effect of swirl number on combustion characteristics such as temperature, velocity, gas concentrations in a natural gas diffusion flame was investigated using numerical simulations carried out using the commercial computational fluid dynamics (CFD) code by choosing appropriate model parameters.
