  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. The Influence of Roughness on Electrical Properties of Single Rock Fractures

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Yu Hou; [2023]
    Keywords : Single fracture; Roughness; Current; Electrical properties; Relative standard deviation; Numerical simulations; Enkelfraktur; Grovhet; Ström; Elektriska egenskaper; Relativ standardavvikelse; Numeriska simuleringar;

    Abstract : To investigate the relationship between the structural characteristics of rough single fracturesand the electrical properties of the rock. In this study, a series of physical models of roughand smooth single fractures were established using the finite element method and Ohm's lawto test the electrical conductivity. READ MORE

  6. 5. Evaluating the pressure pulse in a flexographic printing press : Linking process parameters to specific pulse shapes

    University essay from KTH/Hållfasthetslära

    Author : Anton Hedström; [2023]
    Keywords : Flexography; printing; mottle; dot-gain; pressure; contact; Flexografi; tryck; flammighet; punktförstoring; tryckpuls; kontakt;

    Abstract : In the printing industry quality is key, this is because a product is printed for a better appearance or to convey information. If the packaging for a product looks bad customers will get a bad first impression of the product. The quality of the print can be affected by many different factors. READ MORE
