1. 1. CFD-simulations of urea-waterspray in an after-treatment systemusing Star-CCM+

   Master-uppsats, KTH/Mekanik

   Författare :Emelie Trigell; [2018]
   Nyckelord :after-treatment systems; selective catalytic reaction SCR ; AdBlue; multiphase flow; multi-component liquid; Unsteady Reynolds Average Navier Stokes RANS ; wall film formation; solid deposits; efterbehandlingssystem; selektiva katalytiska reaktioner; AdBlue; flerfasstr ¨ommning; flerkomponentvätska; Unsteady Reynolds Average Navier Stokes; väggfilm; avlagringar;

   Sammanfattning : The legislation has forced the vehicle industry to reduce tail-end emissions. The air pollutant nitrogen oxide (NOX) has been shown to have a negative impact on human health and the environment. One of the key technologies to reduce the levels of NOX emitted from a vehicle is by implementing an after-treatment system. LÄS MER

3. 2. In situ evaluation of terminal and in-line sensor setups for unsteady pressure measurements

   Master-uppsats, KTH/Flygdynamik

   Författare :Otto Kuosmanen; [2016]
   Nyckelord :;

   Sammanfattning : The frequency response of an in-line pressure measuring setup was investigated in order to evaluate its suitability for use in wind tunnel measurements. Testing was conducted in a laboratory environment and a general procedure was developed for both the calibration of the sensors and obtaining the transfer functions for the setup. LÄS MER

4. 3. The movement of the rider’s hand related to the horse’s behaviour and the stride cycle

   Master-uppsats, SLU/Dept. of Anatomy, Physiology and Biochemistry

   Författare :Marie Eisersiö; [2012]
   Nyckelord :Equine behaviour; Equitation; Rein tension; Kinematics;

   Sammanfattning : One way of signalling commands to the horse during riding is through applying tension on the reins to create bit pressure in the horse‟s mouth (Terada et al., 2006; Clayton et al., 2011). The skilfulness of the rider in using the hands when applying bit pressure has consequences both for the horse‟s performance and welfare (Manfredi et al. LÄS MER

5. 4. Reglering av avgasningen i en dialysmaskin.

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

   Författare :Andreas Stolt; [2009]
   Nyckelord :Technology and Engineering;

   Sammanfattning : The current control strategy in the degassing system in a Gambro AK200S dialysis machine leads to a rather noisy flow upstream in the machine. This is where different concentrates are added to the dialysis fluid and as the control of this adding is rather slow the unsteady flow leads to an unsteady conductivity of the dialysis fluid, which makes it difficult to evaluate the effect of the dialysis treatment.

7. 5. Experimental Campaign on a Generic Model for Fluid-Structure Interaction Studies

   Magister-uppsats, KTH/Kraft- och värmeteknologi

   Författare :Hakim Ferria; [2007]
   Nyckelord :aeroelasticity; boundary layer; flutter; reduced frequency; unsteady pressure measurement; shock wave;

   Sammanfattning : Fluid-structure interactions appear in many industrial applications in the field of energy technology. As the components are more and more pushed to higher performance, taking fluid-structure interaction phenomena into account has a great impact on the design as well as in the cost and safety. LÄS MER
