1. 1. Temperature measurement in flames using TLAF, alkali emission and OH UV absorption

   Magister-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

   Författare :Yuhe Zhang; [2018]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : There is a continued need for reliable and convenient nonintrusive thermometric techniques for better understanding and effective control of combustion related processes. In this thesis, three spectroscopic thermometric methods were studied to evaluate the hot flue gas temperatures provided by a multi-jet burner. LÄS MER

3. 2. Measurements and analysis of atomic emission from atomic Li, Na, and K seeded in different flames for potential application to temperature sensing

   Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

   Författare :Yuhe Zhang; [2017]
   Nyckelord :Flame Emission Spectroscopy; temperature measurement; alkali metal atoms; Physics and Astronomy;

   Sammanfattning : Alkali metal atoms, especially sodium and potassium, show an intense fluorescence in hot flue gases. The bright fluorescence emitted by alkali metal atoms offers a large potential for spectroscopic combustion analysis. LÄS MER
