  1. 1. 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

  3. 2. Experimental pressure loss analysis in a mini tube for a fully developed turbulent airflow. : Mini channels of lengths 22.5 mm to 150 mm in length with a constant diameter of 1.5 mm

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Soumen Ghosh; [2022]
    Keywords : Experimental fluid mechanics; Pressure drop; friction factor; Internal flow; fully developed flow; turbulent flow; Fluid mechanics; Ideal gas; Moody s chart; Additive manufacturing; compressible flow; turbine blade cooling; mini channel;

    Abstract : The cooling systems in a gas turbine are especially important as the turbine blades and vanes are exposed to extreme temperatures. The relatively cool air is extracted from the compressors and fed to the turbines to cool the turbine blades. READ MORE

  4. 3. Development and study of noise generation from propellers

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Anton Anton Dunström; Fredrik Skjernov; [2022]
    Keywords : Silent propellers; Propeller development; Noise generation; Skew angle; Blade Area Ratio; Openprop; NATO STANAG no. 1136; Swedish defense and Research Agency FOI ; James Fisher Defense.; Tysta propellrar; Propellerutveckling; Ljudskapande; Skevningsvinkel; Bladtäckningsarea; Openprop; NATO STANAG no. 1136; FOI; James Fisher Defense.;

    Abstract : Noise generation from underwater activities propagates into the marine environment.For marine vessels the propulsion system generates the most noise during itsoperations. Naval vessels that want to operate without being detected want to controlthe sound generating properties of the vessel. READ MORE
