   Sammanfattning : A condensed treatment of conventional beam physics (both linear and nonlinear) is given for the non-expert; this constitutes a minimum knowhow for constructing simulations of rudimentary beamlines. The criteria for an ideal nonlinear charged-particle simulation algorithm are then presented, leading to the derivation of a symplectic, explicit, Lorentz-covariant integrator. LÄS MER

3. 2. Fast devolatilization of biomass : An experimental study using high-speed imaging, relevant for suspension firing technologies

   Sammanfattning : We have performed experiments using imaging techniques in a flame-assisted, drop-tube reactor with optical access, to extract information relevant to the improvement of multi-particle devolatilization models. These models could be of interest for different suspension firing techniques, such as entrained flow biomass gasification, (EFBG) and oxyfuel combustion. LÄS MER
