  1. 1. Solving the incompressible Navier-Stokes equations in 3-D to model gas flow in a room

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Fredrik Malmström; [2024]
    Keywords : ;

    Abstract : The thesis proposes to model the flow of gases in a room by solving the incompressible Navier-Stokes equations in three dimensions. The transportationof scalars such as temperature and concentration of CO2 is modeled by solving the advection-diffusion equation, and the effects of temperature on thevelocity is accounted for by employing the Boussinesq approximation.

  2. 2. Sensorless Field-Oriented Control and Position Estimation

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Roberts Bitenieks; Lars Brander; [2023]
    Keywords : Sensorless rotor position estimation; High-frequency injection; Technology and Engineering;

    Abstract : This master's thesis investigates the feasibility of implementing field-oriented control for a BLDC motor without relying on a position sensor from a standstill up to 400 rad/s. To achieve this objective, various approaches were used at standstill and high speeds. READ MORE
