   Sammanfattning : The challenges faced in today’s industry require materials capable of working in chemically aggressive environments at elevated temperature, which has fueled the development of oxidation resistant materials. All-Oxide Ceramic Matrix Composites (OCMC) are a promising material family due to their inherent chemical stability, moderate mechanical properties, and low weight. LÄS MER

3. 2. Variability of turbulent fluxes (momentum, heat and CO2) during Upwelling conditions. A case study

   Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

   Författare :Carlos Román Cascón; [2010]
   Nyckelord :CO2 fluxes; upwelling; marine boundary layer; turbulent fluxes;

   Sammanfattning : Measurements of turbulent fluxes (momentum, sensible heat, latent heat and CO2) at two different heights were studied from data of a tower at Ostergarnsholm Island (Baltic Sea) during one week, while calculations using bulk formulations of fluxes were done with measurements in the tower and in two buoys moored at different locations. Different behaviors are found for the different fluxes. LÄS MER
