  1. 1. Design & Assembly of a Modular 1-Cylinder Steam Expansion Test Rig for the Evaluation of Piston Rings and Valve Mechanisms

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Pinaki Das; [2023]
    Nyckelord :Steam; Test Rig; Expander; Steam; testrigg; expander;

    Sammanfattning : The need for renewable and environmentally sustainable power generation has increased manifolds in the recent years. Extensive research has been carried out for better solutions. One such solution is steam power generation. LÄS MER

  3. 2. Near-linear time expander decomposition in practice

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Isaac Arvestad; [2022]
    Nyckelord :;

    Sammanfattning : An expander decomposition is a partitioning of vertices such that each partition is an induced expander. Recently Saranurak and Wang [SW19] gave a randomized algorithm for computing expander decompositions in O(Ø-1m log4m) time. This was the first near linear time algorithm with respect to the number of edges m. LÄS MER

  4. 3. Optimal dead space in axial-type expander

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Martin Karman; [2022]
    Nyckelord :Dead space; Expander; Steam engine; Tolerance analysis; Axial-kolvmotor; Effektivitet; Expansionskammare; Kolv; Ångmotor;

    Sammanfattning : In this thesis a method for determining optimal dead space in an axial-type expander is developed. The axial-type expander in question is for use in a steam engine, a environmental friendly and fuel-agnostic alternative to the ICE-engine. LÄS MER

  5. 4. Designing of two load bearing surfaces in a modern high-speed steam engine

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Anders Söderbäck; [2022]
    Nyckelord :Ranotor Modern high-speed steam engine mechanical engineering KISSsoft Bevel gears; Ranotor Ångmotor KISSsoft Maskinteknik;

    Sammanfattning : The topic of this thesis is the designing of two load bearing surfaces in a modern high-speed steam expander. One of the surfaces is a synchronizing gear structure and the other a conical surface. The goal besides the design is to calculate the contact pressure these surfaces experience during operation.

  7. 5. Performance Investigation & Gas Exchange Assessment of Exhaust Piston–assisted Turbocharged Engine (EPTE) Concept : A simulation-based assessment

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Nachiketh Lingachari Acharya; Saurav Dasgupta; [2021]
    Nyckelord :;

    Sammanfattning : There is an increasing stringency in the emission legislation within the transport industry along with ambitious performance demands from the customer side. These have pushed the vehicle manufacturers and relevant component suppliers to develop and integrate a wide portfolio of engine technologies. LÄS MER
