1. 1. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings

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

   Author : Nipon Roy; [2023]
   Keywords : Finite element modelling; Air bearing; Multiphysics simulations; Air lubrication; surface texture; Topology optimization;

   Abstract : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. READ MORE

3. 2. Mathematical modelling andsimulation for tumour growth andangiogenesis

   University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

   Author : René Edgardo Luna; [2021]
   Keywords : Multiscale modelling; tumor growth; angiogenesis; agent-based model; variance reduction;

   Abstract : Cancer is a complex illness that affects millions of people every year. Amongst the most frequently encountered variants of this illness are solid tumours. The growth of solid tumours depends on a large number of factors such as oxygen concentration, cell reproduction, cell movement, cell death, and vascular environment. READ MORE

4. 3. Towards Identification of Effective Parameters in Heterogeneous Media

   University essay from

   Author : David Johansson; [2020]
   Keywords : parameter identification; multiscale modelling; homogenization theory; partial differential equations; inverse modelling;

   Abstract : In this thesis we study a parameter identification problem for a stationary diffusion equation posed in heterogeneous media. This problem is closely related to the Calderón problem with anisotropic conductivities. The anisotropic case is particularly difficult and is ill-posed both in regards to uniqueness of solution and stability on the data. READ MORE

5. 4. Virtual characterization of composite materials for aero-engine components

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

   Author : Facundo Masari; [2020]
   Keywords : Composite; simulation; multiscale; modelling; UD; NCF; prepreg; aerospace; engine;

   Abstract : Since its beginnings, the aerospace industry has been interested in lowering the weight of aircraft. Moving from performance and economic drivers to environmental design parameters, the weight has continuously been a major focus for this industry. READ MORE

6. 5. Numerical investigation on the effects of out-of-flatness on leakage in metal-to-metal seals

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

   Author : Lumi Canhasi; [2017]
   Keywords : ;

   Abstract : Since the usage of pressurized systems, there has been a challenge to prevent and control leakage of different fluids. When a metal-to-metal face seal is designed, different aspects are to be considered. Its ring shaped sealing surface is designed to prevent leakage and also to maintain pressure. READ MORE
