  1. 1. Construction of a Heat Transfer Rig based on Energy Balance for Rapid Production of Correlations for Additively Manufactured Geometries

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

    Author : Joaquin Quesada Zeljkovic; [2019]
    Keywords : ;

    Abstract : This thesis has set the first milestones towards building a Nusselt number correlation that adapts to the current state of art designing and manufacturing processes at Siemens Industrial Turbomachinery AB, focusing on cooling mini-channels produced with Additive Manufacturing.  Additive manufacturing (AM), also known as 3D printing, is a gamechanger technology that has revolutionised manufacture and design know-how, bringing down production cost, time and waste.
