in this work, result of experimental investigation on interaction of fuel spray generated by a swirled type injector, with air motion in a prototype cylinder are presented. experiments were carried out by planar imaging and particle image velocimetry (piv) techniques in order to provide information about the spray structure evolution and instantaneous velocity distribution of air motion and fue...

High-velocity oxy fuel (HVOF) sprayed coatings can improve the corrosion resistance of bare ASTM SA213-T22 boiler steel. In this report, we have investigated NiCrMoFeCoAl-30%SiO2 and NiCrMoFeCoAl-30%Cr2O3 composite were deposited on steel for protection. High-temperature studies conducted in a molten salt (Na2SO4-60%V2O5) environment at 700ºC under thermo-cyclic conditions. The as-sprayed are c...

On the basis of 2D hydro-base simulations, where a super-high velocity spherical DT impactor collides against a spherically-compressed stationary DT main fuel, the ignition and burn dynamics in the impact fast ignition (IFI) scheme has been investigated. It is found that the energy conversion from the impactor kinetic energy to its internal energy at the collision is not so high (20 ~ 40 %) sin...

High-entropy alloys (HEAs) have great potential to be used as high-temperature materials and in coating material applications due their combination of strength, ductility, thermal stability, wear, oxidation resistance. In this work, a new HEA alloy based on NiCoCrAlSi composition was designed deposited into metallic coatings by high-velocity oxy-fuel (HVOF) air plasma spray (APS) processes, wit...
