Chemiluminescence spectroscopy to explore the flame temperature

An Experimental Study on the Measurement of Fuel to Air Ratio Using Flame Chemiluminescence

Abstract—This study is aiming at establishing the relationship between the optical signal of flame and an equivalent ratio of flame. In this experiment, flame optical signal in a furnace is measured using photodiode. The combustion system is composed of metal fiber burner and vertical furnace, and flame chemiluminescence is measured at various experimental conditions. In this study, the flame c...

Simple Laser-Induced Fluorescence Setup to Explore Molecular Spectroscopy

We will demonstrate a relatively simple, affordable and highly visual experiment to explore molecular spectroscopy by measuring the laser-induced fluorescence (LIF) spectrum of the iodine molecules at room temperature. Iodine is a uniquely suited molecule for LIF measurements since it conveniently absorbs about 20,000 lines in the 490to 650-nm visible region of the spectrum and serves excellent...

Explore attitude mythical and the archetype to design cultural signs

Cultural signs are simple graphic forms. Signs compressed by the rich culture of nations. They are view form content facial and conceptual countries in small modle also they have reflection of reserves the archetype a nation. Archetypes are primary and stable pattern mentally. They are product collective experience over the thousands of years. Archetype represent itself in every human aspect, i...

Flame-enhanced laser-induced breakdown spectroscopy.

Flame-enhanced laser-induced breakdown spectroscopy (LIBS) was investigated to improve the sensitivity of LIBS. It was realized by generating laser-induced plasmas in the blue outer envelope of a neutral oxy-acetylene flame. Fast imaging and temporally resolved spectroscopy of the plasmas were carried out. Enhanced intensity of up to 4 times and narrowed full width at half maximum (FWHM) down t...
