1. Additives in a steam engine to decrease friction : Friction testing of solid lubricants in powder form
Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Sammanfattning : This thesis aims to investigate the coefficient of friction between steel on steel contacts with the addition of solid lubricants such as h-BN, WS2, MoS2 in powder form, in dry conditions and wet conditions. More specifically, the purpose is to enhance the sliding between the piston rings and cylinder block in a modern high temperature steam engine developed by RANOTOR. LÄS MER
2. Optimal dead space in axial-type expander
Master-uppsats, KTH/Maskinkonstruktion (Inst.)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
3. Designing of two load bearing surfaces in a modern high-speed steam engine
Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)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.

4. Material analysis for a rotating inlet valve : Sliding contact in an oil-free super-critical steam environment
Uppsats för yrkesexamina på avancerad nivå, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Sammanfattning : In this thesis, the aim is to study possible tribo-materials for a rotating inlet valve and to find a suitable material combination for the contact. The valve is part of a modern oil-free and high temperature steam engine. Systematic material selection together with tribological tests and wear analyses are performed. LÄS MER
5. Roterande komponenter i en modern högvarvig ångmotor
Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : Denna studie gick ut på att utveckla roterande komponenter i en modern högvarvig ångmotor. Den moderna ångmotorn utvecklas för att ta vara på outnyttjade resurser i form av varma avgaser från industrier och transporter. Vid användning av den moderna ångmotorn främjar det till en hållbar utveckling. LÄS MER
