  1. 6. Principles for Diverting and Merging Viscous Flows : Evaluation and Visualisation

    University essay from Uppsala universitet/Mikrosystemteknik

    Author : Åke Strese; [2017]
    Keywords : Flow splitter; chromatography; diversion; dispersion; laminar; fluid mechanics; MEMS; mock-up; design; delayloop; Mass rate attenuator MRA ; Flödessplitter; flödesdelning kromatografi; dispersion; laminära flöden; fluidmekanik; MEMS; mock-up; delayloop; kvarhållningssyste; mass rate attenuator MRA ;

    Abstract : In the chemistry branch of science is often a chromatograph usedto separate and purify substances in a solution. In achromatograph, different detectors are used to analyse the samplesconstituents. Some detectors destroy the sample during analysis. READ MORE

  2. 7. Accuracy of transient versus steady state forces on a rudder operating in a propeller slipstream

    University essay from Umeå universitet/Institutionen för fysik

    Author : Erik Löfgren; [2015]
    Keywords : Unsteady flows; rudders; propellers; fluid mechanics; performance prediction; unsteady aerofoils;

    Abstract : In computational fluid dynamics (CFD), a transient simulation is in general more costly than computing the steady state of the system, if such a state exists. The velocity field produced by the propeller blades upstream of a rudder is transient in nature, and rudder design using CFD may therefore become very time-consuming. READ MORE

  3. 8. Investigation of the transient nature of rolling resistance on an operating Heavy Duty Vehicle

    University essay from Umeå universitet/Institutionen för fysik

    Author : Petter Lundberg; [2014]
    Keywords : Rolling resistance; Air drag; Heavy Duty Vehicles; Vehicle dynamics; Complete vehicle test; Coastdown; Effective radius; ACEA; Pneumatic tires; Driving resistances; Energy efficiency; Rullmotstånd; Luftmotstånd; Tunga fordon; Fordonsdynamik; Helfordonstest; Utrullningstest; Effektiv radie; ACEA; Pneumatiska däck; Körmotstånd; Energieffektivitet.;

    Abstract : An operating vehicle requires energy to oppose the subjected driving resistances. This energy is supplied via the fuel combustion in the engine. READ MORE

  4. 9. Development of Body and Viscous Contribution to a Panel Program for Potential Flow Computation : Aero Dynamic Analysis and Preliminary Design Tool

    University essay from Institutionen för konstruktions- och produktionsteknik

    Author : Erik Nordin; [2006]
    Keywords : Flygteknik; Aerodynamik; Potentiellströmning; Panelprogram; Kroppsmodell; Gränsskiktsmodell;

    Abstract : The aim of this thesis was to develop a potential flow calculation model which includes computation of flow around aircraft bodies (fuselage, engines) and a boundary layer method which calculates the viscous effects over the aircraft wings. The models developed will be merged with an already existing panel program developed by Saab, Linköping, Sweden. READ MORE
