We investigate laminar Bunsen flames with detailed chemistry and multicomponent transport. The governing equations are discretized by a finite element method on a sequence of adaptively refined, unstructured triangulations. The finite element method is an extension to chemically reacting flows of the streamline diffusion method, including least-squares stabilization of the pressure gradient and...

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 ...

In this study, we developed the design process and optimization of structural parameters a new low-NOx burner based on combustion technology flame stabilization principle. Firstly, basis two-stage swirl burner, applied fuel-graded introduced central nozzle structure to explore influence law graded NOx emissions. Secondly, previously optimized structure, matching between first- second-stage cycl...

Particulates and complex organic mixtures were sampled from the exhaust of a flame retention head residential oil burner combusting No. 2 fuel oil at three firing conditions: continuous at Bacharach Smoke No. 1, and cyclic (5 min on, 10 min off) at Smoke Nos. 1 and 5. The complex mixtures were recovered by successive Soxhlet extraction of filtered particulates and XAD-2 sorbent resin with methy...

The article presents the data related to the flame acquisitions in a liquid-fuel gas turbine derived burner operating in non-premixed mode under three different equivalence fuel/air ratio, which corresponds to a richer, an intermediate, and an ultra-lean condition, near lean blowout (LBO). The data were collected with two high speed visualization systems which acquired in the visible (VIS) and ...
