  1. 21. Turbulence-droplet interaction modelled by One-Dimensional-Turbulence

    Författare :Marco Fistler; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; One-Dimensional-Turbulence ODT ; Multiphase Flow; Turbulence; Droplets;

    Sammanfattning : A stochastic model to study droplet/particle influence on the gas phase using the One-Dimensional-Turbulence model (ODT) is evaluated. To address one of the major problems for multiphase flow simulations, namely computational costs, the dimension-reduced model is used with the goal of predicting certain classes of these flows more efficiently.

  5. 25. Non-linear mechanics of nanocellulose foams

    Författare :Prashanth Srinivasa; Artem Kulachenko; Kristofer Gamstedt; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : There has been a growing interest in nano-fibrillar cellulose (NFC), which has been fuelled not merely by the advantages it presents in terms of strength to weight ratio and biodegradability, but also owing to the recent advances in production techniques. NFC foam is essentially a hierarchical structure, wherein nanofibrils account for the smallest scale, with the pores/cell walls forming the meso scale. LÄS MER
