  1. 1. Simulation of Colorless Distributed Combustion

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Hampus Olsson; [2019]
    Keywords : Computational Fluid Dynamics; Combustion; Gas Turbine; Emission reduction; Flameless Combustion; Colorless Distributed Combustion; Technology and Engineering;

    Abstract : Colorless distributed combustion (CDC) is a promising novel technology to reduce emissions of carbon monoxide and nitrogen oxides in gas turbine combustors. CDC features a different flame regime than conventional gas turbine combustors, associated with a distributed reaction zone and low and uniform temperatures due to dilution of combustion air with exhaust gases.

  3. 2. CFD on Open Wet Cutch to Reduce Drag Losses

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Rimmie Duraisamy; [2017]
    Keywords : transmission; clutch; multiphase CFD; grooves; oil dissipation; drag losses; transmission; koppling; Multifas-CFD; spårmönster; undanträngning av oljan; strömningsförluster;

    Abstract : As the need for highly efficient transmission systems increase, it is imperative to have lower fuel consumption levels. Hence, it becomes crucial to investigate and understand reasons behind various losses occurring within the system. Clutches and gears contribute to the major losses within a transmission system.

  4. 3. The Design and Linearization of 60GHz Injection Locked Power Amplifier

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Luhao Wang; [2016]
    Keywords : Power Amplifier; Injection-locking; Adaptive biasing; predistortion; Technology and Engineering;

    Abstract : The RF power amplifier is one of the most critical blocks of transceivers, as it is expected to provide a suitable output power with high gain, efficiency and linearity. In this paper, a 60-GHz power amplifier based on an injection locked structure is demonstrated in a standard 65 CMOS technology. READ MORE

  5. 4. Quantification and Implementation of Structural Damping in MBS Flexible Bodies

    University essay from Lunds universitet/Mekanik

    Author : Anton Flink; [2015]
    Keywords : Technology and Engineering;

    Abstract : In multi body simulation (MBS) using flexible bodies, damping is an important model input to be able to predict the response of a structure with sufficient precision. The purpose of this thesis has been to estimate the structural damping of an experimental setup and implement the estimated damping into MBS-models of the setup. READ MORE

  6. 5. CFD analyses of the gas flow inside the vessel of a hot isostatic press

    University essay from KTH/Kraft- och värmeteknologi

    Author : Andreas Åkerberg; [2012]
    Keywords : CFD; hot isostatic press; computational fluid dynamics; numerical methods; furnace; pressurized gas; vessel; rapid cooling;

    Abstract : Hot isostatic pressing (HIP) is a thermal treatment method that is used to consolidate, densify or bondcomponents and materials. Argon gas is commonly used as the pressure medium and is isostaticallyapplied to the material with an excess pressure of 500-2000 bar and a temperature of 500-2200oC. READ MORE
