  1. 16. 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

  3. 17. A Comparison of Building Energy Performance Simulation Tools in BIM and non-BIM environments

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Author : Damilare Akinboboye; [2022]
    Keywords : Building Information Modelling BIM ; Building Energy Modelling BEM ; Building Energy Simulation BES ; Interoperability; BPS tools.; Technology and Engineering;

    Abstract : The detailed use of Building Performance Simulation (BPS) tools to estimate the energy use and encourage energy savings solutions is vital in mitigating the energy use for buildings and the production of this energy. Furthermore, the design of energy-efficient and environmentally friendly buildings involves a collaborative effort among professionals in the Architecture, Engineering, and Construction (AEC) industry.

  4. 18. Understanding the correlation between molecular structure of chilled dairy creams and the risk of environmental stress cracking in Tetra Pak® carton packages

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Alejandra Fernandez Castaneda; [2022]
    Keywords : Cream; microestructure; environmental stress cracking; food technology and nutrition; Agriculture and Food Sciences;

    Abstract : Multilayer food packaging are lined with an inner layer of plastic and has excellent barrier properties. However, plastics lose their mechanical properties after being exposed to certain conditions; the combination of factors generates failures in the material such as the appearance of cracks, this phenomenon is known as environmental stress cracking (ESC).

  5. 19. Graphene-based Crack-Free Ceramic Coatings for High-Performance Passive RF Devices

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Haomin Liu; [2021]
    Keywords : ;

    Abstract : Dielectric resonators coated with highly conductive metallic layers are widely used in radio frequency (RF) applications. The quality factor (Q-factor) of resonators is a key figure-of-merit that describes the loss and the energy efficiency of the resonators. READ MORE

  6. 20. Cooling simulation of a BEV electrical machine rotor

    University essay from KTH/Fordonsdynamik

    Author : Lisa Sparv; [2021]
    Keywords : Electrical machine; Rotor cooling; Permanent magnet; Simulation; STAR-CCM ; Elmaskin; Rotorkylning; Permanentmagnet; Simulering; STAR-CCM ;

    Abstract : The thesis work described in this report is about simulation of the cooling of an electrical machine rotor. Limitations and simplifications were made on the CAD model of the rotor with the purpose of reducing the simulation time, for it to then be used for CFD-simulations using STAR-CCM+. READ MORE
