1. 1. Measurements of Film Flow Rate in Heated Tubes with Various Axial Power Distributions

   Författare :Carl Adamsson; Henryk Anglart; Bengt Sundén; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; film flow; film thickness; dryout; power distribution; annular flow; Atomic physics; Atomfysik;

   Sammanfattning : Measurements of film mass flow rate for annular, diabatic steam-water flow in tubes are presented. The measurements were carried out with four axial power distributions and at several axial positions at conditions typical for boiling water reactors, i.e. 7 MPa pressure and total mass flux in a range from 750 to 1750 kg/m2s.

3. 2. Flow Measuring Techniques in Steady and Pulsating Compressible Flows

   Författare :Fredrik Laurantzon; Henrik Alfredsson; Björn Lindgren; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flow measuring; compressible flow; steady flow; pulsating flow; hot-wire anemometry; cold-wire anemometry; Engineering mechanics; Teknisk mekanik;

   Sammanfattning : This thesis deals with flow measuring techniques applied on steady and pulsatingflows. Specifically, it is focused on gas flows where density changes canbe significant, i.e. compressible flows. LÄS MER

4. 3. Känsla för skådespelarkonst : mot en förståelse av tysta kunskaper och görandets fenomenologi

   Författare :Ann Enström; Ringby Per; Ulrika von Schantz; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; Gender; theatre; acting; performance; performativity; emotion; feeling; affect; mood; atmosphere; body; sensibility; senses; sensuous; situated; tacit knowledge; doing; act; action; kinesthesia; hermeneutics; phenomenology; intentionality; ontology; becoming; expression; intensity; rhythm; response; touch; flow; devotion; vulnerability; Literature; litteraturvetenskap;

   Sammanfattning : The primary argument in this thesis is that the common assumption that an actor has emotion inside him- or herself which can be evoked and projected outwards is an outdated misconception. A proposition is made to replace this possessive acting model, which underpins the realist tradition and is based on the popularized aspects of Stanislavsky’s system for actor training, by a situational acting model.

7. 5. Experimental Heat Transfer, pressure drop, and Flow Visualization of R-134a in Vertical Mini/Micro Tubes

   Författare :Wahib Owhaib; Björn Palm; Tassos Karayiannis; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Minichannel; microchannel; heat transfer; pressure drop; single-phase; two-phase; flow boiling; flow visualization; dry out; bubble behavior; flow pattern.; Mechanical energy engineering; Mekanisk energiteknik;

   Sammanfattning : For the application of minichannel heat exchangers, it is necessary to have accurate design tools for predicting heat transfer and pressure drop. Until recently, this type of heat exchangers was not well studied, and in the scientific literature there were large discrepancies between results reported by different investigators. LÄS MER
