Active flow control methods based on dielectric barrier discharge plasma actuators can be used to increase the efficiency of combustion systems. In this study, influence location bluff body in a non-premixed burner non-reactive field fuel and oxidizer is investigated numerically. Flow properties spatial mixing deficiency (SMD) are calculated evaluate actuator's reactants' inside burner. The res...

nowadays, utilization of blended fuel in internal combustion engine is one of main topics in vehicle industries. the synergy effect will be highlighted when the potential of each fuel is employed and the engine performance will improve consequently.  in this research, the laminar flame speed of methane (main component of reference fuel for natural gas) and isooctane (main component of reference...

Maximization of the fuel economy of the lean burn spark ignition (SI) engine strongly depends on precise air-fuel ratio control. A great challenge associated with the air-fuel ratio feedback control is the large variable time delay in the exhaust system. In this paper, a systematic development of an air-fuel ratio controller based on post lean NOx trap (LNT) oxygen sensor feedback using linear ...

A novel ammonia/hydrogen dual-fuelled Linear Joule Engine Generator (LJEG) is developed for medium to large scale power generations and electrification of ship propulsion systems. The characteristics premixed combustion the LJEG are investigated through chemical kinetic modelling. Three representative mechanisms compared based on their accuracy reproducing experimental results. With robust low ...

This article analyzes the results of a numerical study effect initial injection mass and temperature oxidizer on tridecane (C13H28) combustion process. During research work, KIVA software package was used. Based performed simulation, distribution fuel droplets concentration CO2 were obtained for various values injected liquid in chamber. After analyzing study, it turned out that effective is 9 ...

The hypergolic reaction between the recently developed green propellant combination consisting of an ionic liquid and highly concentrated hydrogen peroxide was investigated for various fuel to oxidizer ratios heights fall. influence catalytic copper additive on ignition delay time (IDT) analyzed. Flame emission/absorption spectroscopy revealed chemical constituents. All emission spectra were do...

A newly developed heavy duty diesel engine in dual fuel mode of operation has been studied in detail. The main fuel would be natural gas and diesel oil as pilot injection. The importance and effects of mixture preparation and formation through ports, valves and in cylinder flow field with different swirl ratio and tumble on diesel combustion phenomena is an accepted feature which has been studi...

Spatial distributions of temperature, major species, and OH mole fractions under moderate or intense low-oxygen-dilution (MILD) conditions in a laminar-jet-in-hot-coflow configuration were measured using spontaneous Raman laser-induced-fluorescence methods. A preheated mixture 18% CH4/82% N2 at 1100 K was used as fuel, while the products laminar, flat, premixed burner-stabilized flame with an e...
