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

    University essay from KTH/Mekanik

    Author : Emelie Trigell; [2018]
    Keywords : 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;

    Abstract : 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. READ MORE

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

    University essay from KTH/Flygdynamik

    Author : Otto Kuosmanen; [2016]
    Keywords : ;

    Abstract : 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. READ MORE

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

    University essay from SLU/Dept. of Anatomy, Physiology and Biochemistry

    Author : Marie Eisersiö; [2012]
    Keywords : Equine behaviour; Equitation; Rein tension; Kinematics;

    Abstract : 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. READ MORE

  4. 4. Reglering av avgasningen i en dialysmaskin.

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Andreas Stolt; [2009]
    Keywords : Technology and Engineering;

    Abstract : 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.

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

    University essay from KTH/Kraft- och värmeteknologi

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

    Abstract : 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.
