Diethyl ether (DEE) is an interesting species for combustion at least two reasons: On the one hand, it used as a kind of ”worst case” reference substance studies concerned with prevention accidental ignition events. other also candidate bio-fuel. For this reason, in work, auto-ignition different /DEE-mixtures (90/10 and 95/5 mol-% /DEE) are studied rapid compression machine (RCM). In RCM, gas m...

The utilization of hydrogen for reciprocating internal combustion engines remains a subject that necessitates thorough research and careful analysis. This paper presents study on the co-combustion with diesel fuel biodiesel (RME) in compression-ignition piston engine operating at maximum load, content up to 34%. employed indication exhaust emissions measurement assess engine’s performance. Engi...

this article proposes a direct method for solving three types of integral equations with time delay. by using operational matrix of integration, integral equations can be reduced to a linear lower triangular system which can be directly solved by forward substitution. numerical examples shows that the proposed scheme have a suitable degree of accuracy.

homogeneous charge compression ignition (hcci) combustion is a pioneer method of combustion in which pre-mixed fuel and oxidizer (typically air) are compressed to the point of auto-ignition. hcci engines can operate with most alternative fuels, especially, dimethyl ether (dme) which has been tested as a possible diesel fuel due to its simultaneously low nox and pm emissions. in this paper a sin...

Ignition is the initial stage of burning the materials. Consequent flame spread over the materials, heat release rate, fire spread across the rooms, and other issues for building fires all depend on that. Ignition of cellulose materials is commonly classified as smoldering or glowing ignition (self-heating ignition) and flaming ignition including piloted and spontaneous ignition. Numerous studi...

For the purpose of providing scientific insights to combustion characteristics spray jet, numerical calculations reacting and non-reacting cases are performed for ECN (engine network) Spray A (n-dodecane combustion) which coupled finite chemistry model PaSR detailed chemical reaction kinetics based on OpenFOAM. The applicability accuracy is verified in case, it found that predicted such as pene...
