1. Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : 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. LÄS MER
2. Experimental Investigation of High Prandtl Number Flow in Additive Manufactured Channels
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : 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. LÄS MER
3. Micro-architectured materials for thermal management : Porous graphite/graphene boiling enhancement structures
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad mekanikSammanfattning : The convergence of the digital and physical world encourages advances in high-speed telecommunication and fifth generation technology. Two-phase heat transfer systems are common engineering solutions. However, due to the large frequency spectra in 5G, the systematic heat generation increases requiring more efficient thermal management. LÄS MER
4. Investigation Of The Influence Of Geometrical Parameters On Heat Transfer In Matrix Cooling : A Computational Fluid Dynamics Approach
Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningsläraSammanfattning : Modern gas turbine blades and vanes are operated at temperatures above their material’s melting point. Active external and internal cooling are therefore necessary to reach acceptable lifetimes. One possible internal cooling method is called matrix cooling, where a matrix of intersecting cooling air channels is integrated into a blade or vane. LÄS MER
5. Dimples in corrugated channels to improve efficiency in plate heat exchangers
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : The development of new heat exchanger patterns is ever changing. Companies are constantly pushing innovation to satisfy costumer needs in terms of thermal efficiency, reliability and serviceability. In this thesis, the implementation of dimples in the corrugated pattern of a plate heat exchanger is investigated to increase the thermal efficiency. LÄS MER
