    Abstract : European Commission (2011) aims to reduce the greenhouse gas emission sby 85-95% by 2050 in comparison to 1990’s levels. Wave energy could be an important step to archiving this goal. This report aims to develop a quantitative risk assessment for the Uppsala University's wave energy converter. READ MORE

  6. 15. Fluid motion analysis in the cryogenic tanks of the upperstage of Ariane 5 during the ascent phase

    University essay from KTH/Aerodynamik

    Author : Christophe Montsarrat; [2017]
    Keywords : ;

    Abstract : In the frame of the improvement of the performances for Ariane 5, an analysis iscarried out to explain the pressure drop observed in the ascent phase of some flights inthe liquid hydrogen (LH2) tank of the upper stage. This stage is mainly idle until therocket is out of the atmosphere but is submitted to important excitation throughoutthe ascent phase in the atmosphere. READ MORE
