Many of today's employees began their Scania career with their degree project.\nBackground\nThe project aim is to investigate and quantify the performance impact of geometric design features in high pressure liquid injectors and their dependence on nozzle boundary conditions.\nObjective\nThe expected outcome is to isolate the qualitative impacts of the injector flow conditions on the combustion performance and the liquid spray morphology. Typical spray properties to be studied include spray target angle, spray cone angle and spray tip penetration.\nJob description\nFocus will be on running simulations on a given geometry and the postprocessing of model results. However, if interesting new design ideas evolve, other geometries could be included if time allows.\nThe simulations are done in two steps. Firstly, a 3-fluid (liquid, fuel vapor and air) nozzle flow simulation is conducted and time resolved flow results from the nozzle orifice are extracted. Secondly, these results are transferred to a Lagrangian spray model for high pressure liquid injection, from which the combustion performance is assessed.\nThe simulations are done using the AVL Fire 3D CFD software package. We work in a Linux environment with very powerful hardware and a simulation is usually completed in 10 hours. Postprocessing is usually done with scripts (e.g. bash, awk, Perl, Python and Matlab) and a plotting program (e.g. XMGRace or GnuPlot).\nEducation/program/focus\nMaster of Science in Mechanical Engineering, Engineering Physics or similar, with specialisation in modelling and simulation.\nNumber of students: 1 or 2\nStart date for the thesis work: Jan 2027 or according to an agreement.\nEstimated time required: 5 months\nContact persons and supervisors\nDennis Konstanzer, Expert Engineer, +46855389298 \nNiclas Wiker, System Integration and Performance Manager, +46855352745 \nApplication:\nYour application must include a CV, personal letter and transcript of grades.\nA background check might be conducted for this position. We are conducting interviews continuously and may close the recruitment earlier than the date specified.","description_format":"text","description_chars":2326,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-15T07:52:40Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":1,"expected_fill_days":17,"reasons":["conf:0","velocity","win:early","comp:brand"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/scania-master-thesis-nozzle-design-for-spray-shape-optimization","json_url":"https://alion.io/job/scania-master-thesis-nozzle-design-for-spray-shape-optimization.json","meta":{"generated_at":"2026-10-18T01:13:21Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":2050,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-19T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":445730},"rest":"https://alion.io/mcp/rest/get_company?id=445730"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fscania-master-thesis-nozzle-design-for-spray-shape-optimization"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fscania-master-thesis-nozzle-design-for-spray-shape-optimization"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fscania-master-thesis-nozzle-design-for-spray-shape-optimization"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/scania-master-thesis-nozzle-design-for-spray-shape-optimization\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fscania-master-thesis-nozzle-design-for-spray-shape-optimization"}]}
