  1. 11. Establishing a resource-efficient one-step process for dyeing and hydrophobic finishing of wool with a hydraulic spray atomising system.

    University essay from

    Author : Roos Mulder; [2021]
    Keywords : Wool; continuous dyeing; reactive dyeing; acid dyeing; hydrophobic finishing; hyperbranched polymers; dendrimers; hydraulic spray atomising;

    Abstract : The textile industry is a big environmental polluter, with one of the biggest concerns being water pollution and usage. This necessitates resource efficient methods for wet textile processes. READ MORE

  3. 12. Simulating flow-noise for after-treatment systems

    University essay from KTH/Teknisk mekanik

    Author : Adam Sandström; [2020]
    Keywords : Flow-noise; CAA; DES; non-refelctive boundary conditions; stretched grid; Menter SST;

    Abstract : Modern silencers for heavy vehicle applications are designed to cancel out the sound generated by the effects of combustion and propagation of exhaust gases through the engine after-treatment system. The complex geometry within the compact silencer give rise to self generated (or flow-) noise that contribute to the total sound power radiated at the exhaust outlet. READ MORE

  4. 13. Transient Flow Simulations in Exhaust After Treatment Systems

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : John Walder; [2020]
    Keywords : Computational Fluid Dynamics; exhaust after treatment system; ammonia mixing;

    Abstract : The exhaust after treatment system is responsible for removing particulates and contaminants from the exhaust gases. The flow entering the SCR, a catalyst utilizing ammonia to reduce NOx emissions, was studied. The quality and distribution of flow entering the SCR plays an important role in the efficiency of the systems. READ MORE

  5. 14. Comparison of a hybrid ventilation system and a mechanical ventilation system with heat recovery through life cycle assessment : A case study of a modern Danish office building

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Josefine Nilsson Willkomm; [2020]
    Keywords : life cycle assessment; ventilation system; environmental impact; hybrid ventilation system; mechanical ventilation system with heat recovery; livscykelanalys; ventilationssystem; miljöpåverkan; ventilation; hybrid ventilationssystem; mekaniskt ventilationssystem med värmeåtervinning;

    Abstract : The building sector is responsible for 36% of the energy usage and 39 % of all CO2- emissions in European union (EU). Therefore, it is of great interest to investigate how the building sector can become more energy efficient and lower the environmental impact. READ MORE

  6. 15. Automated Model Generation and Pre-Processing to Aid Simulation-Driven Design : An implementation of Design Automation in the Product Development process

    University essay from Linköpings universitet/Maskinkonstruktion

    Author : Raj Jiten Machchhar; [2020]
    Keywords : CAD; design automation; knowledge-based engineering; simulation-specific models; discretization;

    Abstract : The regulations on emissions from a combustion engine vehicle are getting tougher with increasing awareness on sustainability, requiring the exhaust after-treatment systems to constantly evolve to the changes in the legislation. To establish a leading position in the competitive market, companies must adapt to these changes within a reasonable timeframe. READ MORE
