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...

The ability of Karhunen-Loève ~KL! decomposition to identify, extract, and separate the spatial features that characterize a spatiotemporal system is demonstrated using video images from a combustion experiment and nonstationary states from a phenomenological model. Cellular flames on a circular porous plug burner exhibit a variety of stationary and nonstationary patterns. KL decomposition is u...

Marked inflammation of the cornea (keratitis solaris) is often observed after exposure to strong solar radiation, especially in high altitudes and snow-covered terrain. Using the action spectrum and the solar spectrum, the radiant exposure causing keratitis solaris was calculated for a horizontal surface. The parameters selected were altitude, season, ozone content and albedo. The radiant expos...

The scattering of a partially coherent beam by a deterministic, spherical scatterer is studied. In particular, the Mie scattering by a Gaussian Schell-model beam is analyzed. Expressions are derived for (a) the extinguished power, (b) the radiant intensity of the scattered field, and (c) the encircled energy in the far field. It is found that the radiant intensity and the encircled energy in th...

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...
