  1. 1. Developing a Test Method to Evaluate the Blackout Effect of Uncoated Curtains at Varying Angles

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Sara Muminovic; Christina Lindén; [2023]
    Keywords : Blackout effect; blackout curtain; uncoated woven curtains; angle interval; light transmission; light box; light diffuser; microscopic image analysis;

    Abstract : This study aimed to explore the integration of varying angles in small-scale measurements and assess the light transmission performance of uncoated curtains. A total of four curtains were evaluated: blackout curtain samples 1 and 2 had a weft satin structure, while daytime curtain samples 3 and 4 consisted of a twill structure. READ MORE

  3. 2. Experiments and simulations of gas flow through a NiCd battery

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Sarah Petersson; [2023]
    Keywords : NiCd; battery; porous medium; experiment; CFD; NiCd; batteri; poröst medium; experiment; CFD;

    Abstract : This report describes the thesis work carried out regarding experiments and simulations of the gas flow through a NiCd battery. The objective of the work was to investigate how different geometries of the flip top vent on the battery and the level of porosity of the flame arresting disc impacted the amount of potassium carbonate created at the outlet of the vent.
