  1. 1. Cooling Potential of Methane in Rocket Nozzle Cooling Channels : A Conjugate Heat Transfer Analysis

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Marcus Pettersson; [2019]
    Keywords : ;

    Abstract : The use of hydrocarbons as fuel in rocket propulsion has been of great interest to the aerospace industry in recent years. Specifically, natural gas with a high content of methane has taken the interest of several actors, among them Sweden-based GKN Aerospace who in collaboration with KTH Royal Institute of Technology have started the MERiT project.

  2. 2. Experimental validation of a periodic heat transfer CFD model of a vertical shell and tube heat exchanger

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Patrik Bengtsson; Dilip Kumar Vellore Saikumar; [2019]
    Keywords : ;

    Abstract : Flow obstructions are used as a passive design element in heat exchangers to enhance heattransfer. Further, a change in flow structure can also have a positive effect on the heat transfer. Avertical shell and tube heat exchanger, used to recover heat in the greywater stream, isinvestigated in this study. READ MORE

  3. 3. Transfer Printing and Cellulose Based substrates for modern Textile Printing

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Mona Mrad; [2019]
    Keywords : ;

    Abstract : Digital printing technology is a technique that has been growing since the 1990s and has a high growth potential when it comes to using different ink types and transfer printing techniques. In comparison to screen printing, digital transfer printing techniques have shown to consume less ink and water and are therefore considered to be a more environmentally friendly alternative for textile printing.
