  1. 16. Optical Analysis of the Hydrogen Cooling Film in High Pressure Combustion Chambers

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Fabian Weber; [2019]
    Keywords : optical; analysis; hydrogen; h2; cooling; film; high; pressure; combustion; chambers; rocket; engine; thrust; experimental; oh*; shadowgraphy; flame; emission; lox; liquid; bipropellant; cryogenic; efficiency; heat; flux;

    Abstract : For performance optimisation of modern liquid cryogenic bipropellant rocket combustion chambers, one component which plays an important role in reducing the wall side heat flux, is the behaviour of the cooling film. At the Institute of Space Propulsion of the German Aerospace Center (DLR) in Lampoldshausen, hot test runs have been performed using the experimental combustion chamber BKM, to investigate the wall side heat flux which is -- among other factors -- dependent on cooling film properties.

    Keywords : ;

    Abstract : Counterfeited products present a serious problem in many aspects of society. More specifically, counterfeited mechanical components in machines and structures can cause great health risks. For consumers it can be very difficult to identify a counterfeited product, and many industries try to find ways to easily detect a counterfeit. READ MORE

  4. 18. Tribological performance of different crankshaft bearings in conjunction with textured shaft surfaces

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Lakshminarayana Reddy Tamatam; [2017]
    Keywords : Tribology; journal bearings; engine main bearings; automotive; friction; wear;

    Abstract : Improving vehicle efficiency and complying to stricter exhaust emission legislations are some of the driving factors to advancement in technology of engine components. The main bearings in an internal combustion engine contribute significant amount of friction. These bearings support engine loads and allow free rotation of the crankshaft. READ MORE

  5. 19. Structural Investigations of HiPIMS-deposited Diamond-Like Carbon Thin Films using Raman Spectroscopy

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Andreas Eriksen Tell; [2017]
    Keywords : ;

    Abstract : Diamond-like carbon (DLC) is a versatile material which exhibits excellentmechanical, electrical and optical properties making it suitable for applications rangingfrom biomedical implants to engine components. The properties of DLC thin films aredetermined by the bonding configuration (sp3/sp2 fraction) of its carbon atoms. READ MORE
