Flame stability in a lean fuel-air mixture is studied experimentally in a metal–ceramic porous burner. Ceramic medium with small pore diameter is inserted on the metal porous medium in order to prevent flame blow off. Position of the flame is obtained with the measured temperature profile in the sidewalls of the burner. Temperature profiles are obtained at different firing rates and equivalence...
in this work, the feasibility study for design of a laboratory sample rde which has an annular geometry with diameter of 76 mm and length of 101 mm has been performed. detonation engines are expected to be used as propulsion system in aerospace applications in the future. several types of detonation engines are currently under examination, including the rotating detonation engine (rde). first, ...
Low caloric sweeteners have been investigated to substitute sugar as an advantage for both nutritional and medicinal purpose. These sugar substitutes are interesting particularly for concepts marketed under a natural claim. Among these, Stevia rebaudiana is a small shrub; its leaves are used as a sweetener. Serial dilution of the hot water Crude extract of S. rebaudiana leaves and aqueous solut...
This paper investigates the effect of ethanol-unleaded gasoline blends (E0,E10,E25,E35,andE65) computer interfaced, four-stroke single cylinder compression ignition engine. The said engine wasconverted to spark ignition and carburetion to suit ethanol fuel. A suitable provision was provided on theengine to vary the compression ratio thereby making the engine adaptable to operate at lowercompres...
Low radiation intensity heat transfer from methane blue flame has turned into a challenge in industry. The addition of soot into the flame can enhance the radiation. However, the effect of adding soot on chain reaction of methane combustion and NO & CO emissions has not been assessed. Furthermore, one of the most important factors to be considered is the size of the fine particles. Therefore, t...
The tests were carried out with the spark timing adjusted to the maximum brake torquetiming in various equivalence ratios and engine speeds for gasoline and natural gas operations. In thiswork, the lower heating value of gasoline is about 13.6% higher than that of natural gas. Based on theexperimental results, the natural gas operation causes an increase of about 6.2% brake special fuelconsumpt...
