Combustion instabilities in gas turbine engines often give rise to acoustic resonances. These resonances occur as manifestations of different acoustic modes, of which a single or multiple modes may be present. In this work, the acoustic behavior of a model gas turbine combustor, developed at DLR Stuttgart by Meier, was investigated using both syn(thetic) gas and standard hydrocarbon fuels. Syng...

This work describes a laboratory method to synthesize aerosols with properties similar to those emitted by ocean going ships. In this method, an oxy-hydrogen flame burner nebulizes and combusts heavy fuel oil (HFO). The oil was fed to the burner via a syringe pump at a maximum rate of 15 ml/h. Adjusting the feed temperature of the oil and the use of a quenching ring in the burner, it is possibl...

Dalam perkembangan teknologi pengecoran logam, burner yang baik adalah menghasilkan panas optimal dalam membakar tungku peleburan logam sehingga dapat mempercepat leburnya logam. Burner sebagai alat mengatur pembakaran melakukan pencampuran antara udara dan bahan bakar dihasilkan meningkatkan efisiensi pembakaran. Tujuan penelitian ini untuk merancang tipe gun berbahan LPG mengarah pada produks...

This paper presents the results of validation calculations nuclear fuel depletion calculation module CBZ reactor physics code system, CBZ/Burner. Validation were conducted using post irradiation examination data obtained at Fukushima-Daini Unit 2 and Takahama 3. The nuclide number densities calculated with CBZ/Burner compared measurement values, generally good agreement was obtained. sensitivit...

The baseline specifications of European XFEL give a range of wavelengths between 0.1 nm and 2 nm. This wavelength range at fixed electron beam energy of 17.5 GeV can be covered by operating the SASE FEL with three undulators which have different period and tunable gap. A study of the potential for the extending the spectral range accessible to the XFEL in the direction of longer wavelengths is ...
