   Sammanfattning : Transient vehicle thermal management simulations have the potential to be an important tool to ensure long component lifetimes in heavy-duty vehicles, as well as save development costs by reducing development time. Time-resolved computational fluid dynamics simulations of complete vehicles are however typically very computationally expensive, and approximation methods must be employed to keep computational costs and turn-around times at a reasonable level.

3. 2. Efficiency of a Time-of-Flight Detection System for Analysis of Wall Material From Controlled Fusion Devices

   Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

   Författare :Embla Morast; Einar Svantesson; [2017]
   Nyckelord :;

   Sammanfattning : Time-of-flight elastic recoil detection analysis (ToFERDA)is a method for material analysis which has provenadvantageous when examining wall samples from fusion devicesas well as for tracking tracer isotopes such as deuterium, oxygen-18 and nitrogen-15. When ToF-ERDA data is processed tocalculate the composition of a material, the detection efficiencyis used to compensate for the lower detection rate of lighterelements. LÄS MER
