  1. 1. Improving Water Droplet Prediction for Vehicle Exterior Water Management: Insights from Experimental and Simulation Studies

    University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Author : Anton Labbé; Mahim Ahsan; [2023]
    Keywords : Computational Fluid Dynamics; Volume of Fluid; Kistler Correlation; Water Droplet; Wind Tunnel Measurement; Exterior Water Management.; Beräkningsfluidmekanik; Volume of Fluid; Kistler-korrelation; Vattendroppar; Vind Tunnel Experiment; Exteriört Vattenhantering.;

    Abstract : This thesis focuses on the study of water transportation on vehicle surfaces, which is crucial for ensuring the unobstructed operation of sensors and cameras in autonomous vehicles. The research aims to develop and validate experimental and simulation methods to enhance the understanding of water droplet behaviour and to create accurate models for computational fluid dynamics (CFD) simulations.

  3. 2. Simulations of complete vehicles in cold climate at partial and full load driving conditions

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Akshay Jamadagni H N; [2020]
    Keywords : Boundary conditions; climatic wind tunnel; computational fluid dynamics; temperature; vehicle thermal management.;

    Abstract : In this study, CFD simulations of a complete truck are carried out to investigate the effect of altered simulation settings at cold climatic conditions. The aim of this study is to obtain knowledge through CFD simulations performed on a selected driving condition namely at a vehicle speed of 93 kph, an ambient temperature of -20 °C and for an engine operating at 25 % load.

  4. 3. Aerodynamics of Sailing Yachts : Force, Pressure and sail shape measurements as bridge between experiments and numerical simulations

    University essay from KTH/Marina system

    Author : Francesco Giacobone; [2017]
    Keywords : ;

    Abstract : The present work reports the first systematic results obtained in wind tunnel and at full scale with theexperimental apparatus developed within the joint project among Politecnico di Milano, North Sails andCSEM. The steady state upwind aerodynamics of sailing yachts are investigated through the contemporarymeasurement of global forces, distributed pressures and sail flying shapes, and with numerical simulationsbased on Potential Theory and Navier-Stokes equations.

  5. 4. Measurement of the convective heat transfer with wind : Developing and testing an Earth Scaled Atmospheric Temperature Sensor

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Philipp Wittmann; [2016]
    Keywords : Wind; ATS; heat transfer; air temperature sensor; atmospheric temperature sensor;

    Abstract :    The HAbitability, Brine Irradiation and Temperature Package (HABIT) instrument of the ExoMars Surface Platform will investigate the present day habitability of Mars at the near surface environment. This instrument includes three Atmospheric Temperature Sensor's (ATS's) which are similar to the ones previously used on the Rover Environmental Monitoring Station (REMS) of the Mars Science Laboratory (MSL) rover, that has now been operating on Mars for more than four years.

  6. 5. 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
