  1. 1. Life Cycle Assessment of Borehole Thermal Energy Storage

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Saga Karlsson; [2022]
    Keywords : ;

    Abstract : Borehole thermal energy storage (BTES) is a technology used to store energy between seasons. It could therefore be a solution to the seasonal mismatch between the use and production of (renewable) energy, which can be used to increase energy efficiency and reduce greenhouse gas emissions.

  3. 2. Identifying Important Features to Minimize Hole Deviation in Percussive Drilling

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Ketan Dhananjay Deshpande; [2021]
    Keywords : Bending; Buckled profile; Drilling; Hole deviation; Mathematical model; Böjning; Buckled profil; Borrning; Hålavvikelse; Matematisk modell;

    Abstract : Hole deviation is one of the most significant problems in drilling applications. Deviated holes result in inefficient blasting and have severe economic impacts due to increased equipment consumption. Conversely, straighter holes help in increasing production scales and reduce operational costs. READ MORE

  4. 3. Cooling Strategy Influence on Temperature in ETD Center

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Oskar Edinger; [2021]
    Keywords : Machining; Drilling; Exchangeable tip drill; 316L Stainless steel; Thermocouple; IR Thermography; Skärande bearbetning; Borrning; Löstoppsborr; 316L Rostfritt stål; Termoelement; IR Termografi;

    Abstract : Striving for increased productivity while maintaining hole quality and high process robustness when drilling requires knowledge about the working principles of heat generation, mechanics and a proper cutting fluid that aids in cooling, lubricating and evacuating chips from the cutting zone. If the heat generated in the tool-workpiece and tool-chip interfaces does not exit the cutting zone adequately through the chips, the workpiece material or the redistribution of coolant the hole quality can be impacted negatively and breakdowns may occur which reduces overall productivity.

  5. 4. Atomic wear mechanisms of hard chrome against Al2O3

    University essay from Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Author : Raul Fierro Tobar; Marius Yuku; [2021]
    Keywords : Wear mechanisms; DFT; MD; hard chrome; aluminium; RDF; adhesive; abrasive; Nötning; DFT; MD; hårdkrom; aluminium; RDF; adhesiv; abrasiv;

    Abstract : Hard chrome exhibit hardness of about 70 HRC and lubricity that prevents seizing and galling and is therefore the common first choice for engineers to reduce friction and minimize wear. These properties enable engineering applications such as cutting and drilling, especially in manufacturing, production and consumer good industries. READ MORE

  6. 5. Control Implementation and Co-simulation  of A 6-DOF TAU Haptic Device

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

    Author : Yang Zhang; [2020]
    Keywords : Co-simulation; Haptic rendering; Multi-body simulation MBS ; Parallel robot; Samsimulering; Haptisk rendering; Multi-body simulation MBS ; Parallell robot;

    Abstract : In the research area of virtual reality, the term haptic rendering is defined as the process of computing and generating the interaction force between the virtual object and the operator. One of the major challenges of haptic rendering is the stably rendering contact with a stiff object. READ MORE
