1. 1. Effect of temperature on early stage adhesion during TiAlN sliding against Inconel 718 and Stainless steel 316L : High temperature tribology

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

   Author : Ahsan Ali; [2023]
   Keywords : High temperature tribology; Early-stage adhesion; Adhesive wear; Friction; Wear resistant coatings; Physical vapour deposition PVD coatings; TiAlN; Tungsten carbide WC Co ; Difficult to machine super alloys; Inconel 718; Stainless steel 316L; High-performance materials; Abrasion; Oxidation; Chipping; Ploughing; Characterization;

   Abstract : High-performance materials such as stainless steels and nickel based super alloys are widely used in demanding applications where high mechanical and thermal properties are required. The applications of super alloys are mainly found in jet engines, power plants and gas turbines demanding high fatigue strength, corrosion and oxidation resistance as well as wear resistant properties.

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. Experimental Investigation of High Prandtl Number Flow in Additive Manufactured Channels

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

   Author : LINDA YANG; [2023]
   Keywords : Additive manufacturing; Heat transfer; Darcy friction factor; Nusselt number; Minichannel.; Friformsframställning; Värmeöverföring; Darcy friction factor; Nusselt number; Minikanal.;

   Abstract : Additive manufacturing (AM) rapidly evolves and expands into new industries dueto its great design freedom and time savings. Injection molding is an excellentindustry where AM can help reduce cooling time by printing complex coolingchannels for more effective and uniform cooling. READ MORE

5. 4. Thermal Investigation of the Green Revolution Energy Converter : A study on the heat transfer within the GREC in regards of temperature distribution and heat rate

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Wilma Fager; Maja Abrahamsson Bolstad; Emma Gustafsson; Emma Andersson; Matilda Eriksson; [2023]
   Keywords : GREC; Energy; Heat transfer; Heat rate; Temperature distribution;

   Abstract : To reduce emissions, new technological solutions can be of use. One technology which is currently being developed is the Green Revolution Energy Converter, GREC. GREC is an engine with the aim to produce electricity from temperature gradients.  This project is part of a greater project that is divided in two with different focus areas. READ MORE

6. 5. Modelling and Validation of Evaporation Systems; Mass & Energy Balances

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Maja Sondell; [2023]
   Keywords : Evaporation; Evaporation Systems; Modeling; Python; Chemical Engineering; Kemiteknik; Evaporation Rate; Overall Heat Transfer Coefficient; Technology and Engineering;

   Abstract : To evaluate the performance of evaporation systems, performance parameters such as overall heat transfer coefficient and evaporation rate need to be evaluated. These parameters are difficult measure and therefore need to be calculated using other measured data. READ MORE
