1. 16. A comparison of pressurised cylinders in HIP systems using CFD and FEM

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Lisa Lindqvist; [2021]
   Keywords : Hot isostatic pressing; HIP; Pressure vessel; Monoblock; Axisymmetric; FSI;

   Abstract : A hot isostatic press (HIP) is a system which utilises high temperatures and pressure in order to densifyand enhance the material properties of components in the aerospace, automotive and additive manufacturingindustries, to mention a few. Quintus is a world leading manufacturer of HIP systems, and this master’s thesiswork has been written in collaboration with them. READ MORE

3. 17. Meta-Modelling Based Design Optimization of Gas Turbine Blade Cooling Channels

   University essay from Linköpings universitet/Institutionen för datavetenskap

   Author : Namita Sharma; [2021]
   Keywords : Machine Learning; Meta Model; Data Science;

   Abstract : The aim of this paper is to investigate the use of Machine Learning to accelerate the processof gas turbine design optimization. Traditionally, the process simulations involved inoptimization are performed using commercial Computational Fluid Dynamics (CFD) softwaretools to find the best combinations of design parameters under specific conditionsand operational constraints.

4. 18. Shape optimization of axial cooling fan via 3D CFD simulation and surrogate modeling

   University essay from KTH/Strömningsmekanik och Teknisk Akustik

   Author : Martin Granlöf; [2021]
   Keywords : Fan noise; shape optimization; mesh morphing; computational fluid dynamics; computational aeroacoustics; Efficient Global Optimization; Reynolds-averaged Navier-Stokes;

   Abstract : Due to legislative reasons and environmental concerns the automotive and transport sector are shifting their focus from traditional internal combustion engine (ICE) vehicles to development of battery electric vehicles (BEVs). This brings new challanges to design of cooling systems where axial fans are one of the key components. READ MORE

5. 19. 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

6. 20. Numerical Investigation of the Near FieldZone Flow Behavior of Isothermal CornerImpinging Jet Ventilation Using CFD

   University essay from Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

   Author : Too-chukwu C. Ogbuagu; [2021]
   Keywords : Ventilation; Computational fluid dynamics;

   Abstract : Abstract The impinging jet ventilation's importance in providing better air distribution and energy-efficient operation, as well as both its heating and cooling flexibility potential cannot be overemphasized. This is because acceptable indoor air quality and its environmental conditions are essential to occupant’s wellbeing, comfort, productivity, and improved cognitive function. READ MORE
