  4. 4. Single Phase Convective Heat Transfer with Nanofluids An Experimental Approach

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Ehsan Bitaraf Hgahighi; Björn E. Palm; Elena V. Timofeeva; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanofluid; convective heat transfer; thermal conductivity; viscosity; heat transfer coefficient; performance; pumping power; Reynolds number; shelf stability;

    Abstract : Nanofluids (NFs) are engineered colloids of nanoparticles (NPs) dispersed homogenously within base fluids (BFs). Due to the presence of NPs, the thermophysical and transport properties of BFs are subject to change. READ MORE

  5. 5. On Heat and Paper From Hot Pressing to Impulse Technology

    University dissertation from Stockholm : Fiber- och polymerteknologi

    Author : Marco Francesco Carlo Lucisano; [2002]
    Keywords : Paper; Impulse Drying; Heat Transfer; Phase Change; Heat-Pipe Effect; Delamination; Flashing;

    Abstract : Impulse technology is a process in which water is removedfrom a wet paper web by the combined action of mechanicalpressure and intense heat. This results in increased dewateringrates, increased smoothness on the roll side of the sheet, andincreased density. READ MORE
