The gaseous by-product from natural or industrial processes which contain a small concentration of combustible gases is called a low-grade fuel or low calorific value gases (LCVG). Identifying the best strategy for efficient burning of such gases, where there is a bulk production, becomes inevitable to improve the efficiency of a system and reduction of pollutants emission. LCVGs have calorific...

In this study, the effects of mechanical milling and YSZ reinforcing on oxidation behavior of CoNiCrAlY coatings were investigated. Various amounts of YSZ particles (0%, 5%, 10% and 15 wt.%) were mixed with commercial CoNiCrAlY powder and milled for 24 hrs. Then, the mechanically milled and commercial powders were deposited on Inconel 617 substrate using High Velocity Oxygen-Fuel (HVOF) process...

Abstract Dense environmental barrier coatings (EBCs) are an essential prerequisite to exploit the advantages offered by SiC‐based fiber reinforced ceramic matrix composites (CMCs) increase efficiency in gas turbines. Today's state‐of‐the art materials for application as EBCs rare‐earth (RE) silicates which, however, form amorphous phases upon rapid quenching from melt. This makes their processi...

Three-dimensional computational fluid dynamics (CFD) modelling is employed to simulate a typical high velocity oxygen fuel process (HVOF) under laboratory operating conditions. Two different approaches, viz., the continuum and discrete models, are engaged model liquid kerosene, their influence on resulting primary gas investigated. Numerical results of validated against available measurements f...
