Abstract Combustion instability in annular combustors of jet engines is a recurring issue. In this study, the characteristics instabilities for different fuels are investigated by combining maps obtained laboratory-scale combustor equipped with multiple swirling spray injectors (MICCA-spray) and flame describing functions (FDFs) from single sector configuration (SICCA-spray). Two types liquid i...

Catalytic steam reforming of diesel fuel has the potential for producing syngas or hydrogen that can be feed to a cell (especially SOFC) portable power generation. Cost-effective, highly active catalysts with resistance towards carbon formation and sulfur poisoning are critically needed commercialize such technologies successfully. Thus in present work, we have explored CaO-Al2O3 based hydrotal...

A mathematical model for the simulation of spherical bubble dynamics in binary alkane mixtures is presented. Detailed heat and mass transfer phase transition are resolved, air absorption desorption considered. As example mixtures, high-volatile heptane low-volatile dodecane investigated. The component shows a convective counter-intuitive transport opposite to diffusion flux. staggered flux asso...
