  4. 3. Comparative study of residue pellets from cane sugar and palm-oil industries with commercial wood pellets, applied in downdraft gasification

    Författare :Catharina Erlich; Torsten Fransson; Björn Zethraeus; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy engineering; Mechanical and thermal engineering; Mekanisk och termisk energiteknik;

    Sammanfattning : While biomass utilization for energy conversion in the industrialized nations is being largely developed, highly efficient and environmentally friendly, many tropical countries still use biomass at low efficiencies and high emission levels. The main reasons for these gaps are both political and technological: the energy markets are different, the Gross National Product (GDP) differs widely, and the feedstock differs in form and conversion behaviour.

  5. 4. Adaptive Finite Element Methods for the Reynolds Thin Film Model with Cavitation

    Författare :Bertil Nilsson; Sweden Gothenburg Chalmers University of Technology Department of Applied Mechanics; []
    Nyckelord :tribology; Reynolds equation; cavitation; FEM; adaptivity; variational inequality; penalty formulation; error estimation; residual; duality;

    Sammanfattning : The main purpose of this thesis is to use modern goal-oriented adaptive finite element techniques in order to improve the numerical simulation of tribology. Two novel adaptive finite element methods for the Reynolds thin film model including cavitation are presented and their different strategies are compared. LÄS MER
