1. 1. Prospects for standardisation of industrial PET plastics to support the transition towards a circular economy

   University essay from Lunds universitet/Miljö- och energisystem

   Author : Agnes Ström; [2024]
   Keywords : Standard; standardisation; industrial PET; polyethylene terephthalate; circular economy; plastic; Technology and Engineering;

   Abstract : Plastkonsumtionen har ökat markant över tid och har utvecklats till ett viktigt material i dagens samhälle, men med utmaningen att råvaran främst kommer från fossila källor. Användningen av plast är i linje med den linjära ekonomin och den så kallade slit-och-släng-kulturen, vilket bidrar till felaktig hantering av plastavfall och en ineffektiv användning av resurser.

3. 2. Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography

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

   Author : Kaibin Wen; [2023]
   Keywords : Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography; Additiv tillverkning; värmeöverföring; infraröd termografi; ytjämnhet; finita elementmetoden;

   Abstract : Additive manufacturing (AM) has largely improved design freedom compared with traditional manufacturing processes such as casting and milling. The layer-by-layer workflow makes it possible to produce objects with much more complex shapes and structures. READ MORE

4. 3. Design Optimization of Savonius Wind Turbine using CFD Simulations

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Vatsalkumar Manavar; [2023]
   Keywords : Savonius wind turbine; Computational fluid dynamics; Vertical axis wind turbine; Overlap ratio; Distance between blades; Power coefficient;

   Abstract : This thesis is based on a simulation of the Savonius wind turbine. The Savoniusturbine is a simple vertical axis device, which has half cylindrical blades attached to the main shaft opposite to each other which creates the drag force from incoming wind and generates mechanical torque which drives the generator for electricity generation.

5. 4. Pilot Study: Test Rig for Self-lubricating Kaplan Runner Bearings

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

   Author : Bhairav Khadke; [2023]
   Keywords : Hydropower; Kaplan turbine; Self-lubricating bearing Test rig. Hydropower; Kaplan turbine; Self-lubricating bearing Test rig.; Vattenkraft; Kaplanturbin; Självsmörjande lager Testrigg.;

   Abstract : Hydropower has a relatively small impact on the climate and contributes to almost half of Sweden’s electricity production. Vattenfall own and operate roughly 125 large scale hydro power units of which about half utilizes a Kaplan turbine. READ MORE

6. 5. Forced response numerical investigation of a transonic compressor rotor

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

   Author : Mariana Pires Gonçalves Toco Dias; [2023]
   Keywords : Compressor; rotor; blisk; aeroelasticity; aerodynamic damping; CFD; transient; forced response;

   Abstract : The present thesis discusses the forced response of a rotor’s bladed-disk when excited by the periodic force produced by a wake generator, or Inlet Guide Vane (IGV),with 8 equally-spaced blades. These components are part of an axial transonic compressor rig, moreover the Transonic Compressor Darmstadt 1 (TCD1), located at the Technical University of Darmstadt. READ MORE
