1. 1. Particulate matter analysis from engine outlet in heavy-duty diesel vehicles : A study of soot reactivity, morphology and ash-to-soot ratio from the outlet of 6-cylinder and 8-cylinder diesel engines.

   University essay from KTH/Kemiteknik

   Author : Tayisiya Vlasenko; [2023]
   Keywords : Diesel engine; particulate matter; kinetics; soot; heavy-duty vehicles; Dieselmotor; partiklar; kinetik; sot; tunga fordon;

   Abstract : De ökande luftföroreningarna i Europa är ett allvarligt miljöproblem, och vägtransporterna är en av de största orsakerna till detta. För att ta itu med detta problem och uppfylla nya utsläppskrav måste efterbehandlingssystemen för avgaser förbättras. READ MORE

3. 2. A Numerical Study of Melt Pool Heat Transfer in the IVR of a PWR

   University essay from KTH/Fysik

   Author : Yuer Zhao; [2021]
   Keywords : In-vessel melt retention; corium pool; Zr oxidation ratio; melt pool convection; CFD; SST k-ω turbulence model; Smältretention i kärlet; koriumpöl; Zr-oxidationsförhållande; konvektion i en smältpöl; CFD; SST k-ω turbulensmodell;

   Abstract : This thesis aims to provide the thermal condition of melt pool convection by CFD simulation, which is important to the assessment of the invessel melt retention (IVR) strategy widely adopted in Generation III pressurized water reactors (PWRs). As a severe accident mitigation measure, the IVR strategy is realized through external cooling of the lower head of a reactor pressure vessel (RPV). READ MORE

4. 3. Defining Black: Characterization of Soot Reactivity with Thermogravimetrical Methods : Definiera svart: Karaktärisering av sotreaktivitet med termogravimetriska metoder

   University essay from KTH/Tillämpad fysik

   Author : Adarsh Roy Choudhury; [2020]
   Keywords : Diesel Particulate Filter; Chemical Kinetics;

   Abstract : Exhaust emissions in a vehicle has to flow through an exhaust aftertreatment in a diesel vehicle. In a diesel engine, the exhaust emissions are treated with Diesel Oxidation Catalyst (DOC), Diesel Particulate Filter (DPF), and Selective Catalytic Reduction (SCR). Every engine produces a different kind of soot depending on the drive cycle. READ MORE

5. 4. High temperature corrosion in exhaust application for heavy-duty trucks

   University essay from KTH/Materialvetenskap

   Author : Alice Moya; [2019]
   Keywords : high temperature corrosion; austenitic steel; cast iron; cast steel; oxidation; exhaust gas; engine; heavy-duty trucks;

   Abstract : Increasing awareness of environmental protection has made both governments and the industry aim for lowering carbon dioxide emissions. For the transport industry this means increasing engine efficiency, replacing fossil fuels with bio-based fuels or full electrification. READ MORE

6. 5. Shelf life of fresh-cut fruits and salad leaves treated with Pulsed Electric Field (PEF)

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

   Author : Chandan Soni; [2019]
   Keywords : PEF; pulsed electric field; reversible electroporation; calorimeter; metabolic rate; shelf life; fresh commodities; food engineering; livsmedelsteknik; Agriculture and Food Sciences; Technology and Engineering;

   Abstract : Application of Pulsed Electric Field (PEF) treatment on five fresh commodities was analysed for the changes in the metabolic and physiological effects on their shelf life. Treatment parameters were optimised in order to achieve uniform electroporation on the samples, which was analysed by Propidium Iodide staining for the leaf samples. READ MORE
