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. Numerical Modelling of a Packed Bed Thermal Energy Storage for Applications in a Carnot Battery : KTH Thesis Report

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Gabriel Juul; [2023]
   Keywords : Thermal energy storage; Carnot battery; sand; packed bed; granular medium; porous medium; effective medium technique; effective thermal conductivity; paramedic study; 3D model; COMSOL; numerical modelling; Lagring av värmeenergi; Carnot-batteri; sand; packad bädd; granulärt medium; poröst medium; effektiv mediumteknik; effektiv värmeledningsförmåga; parametrisk studie; 3D-modell; COMSOL; numerisk modellering;

   Abstract : This thesis explores the heat transfer characteristics of a packed bed thermal energy storage device through the development of a 3D model in COMSOL Multiphysics. The model is based on a laboratory-scale device consisting of an aluminum box filled with sand, which acts as the thermal storage medium. READ MORE

4. 3. Numerical study of a jet impacting a heated object

   University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

   Author : Moutaz Hammoud; [2023]
   Keywords : Numerical model; COMSOL Multiphysics; Heat transfer; Impinging jets.;

   Abstract : Heat transfer brought about by impinging jets is common in several industrialapplications such as the cooling of heated objects. The purpose of this investigationis to create a numerical model of an impacting jet, then to use it in parametricresearch and in the cooling of an electronic device. READ MORE

5. 4. Theoretical Considerations and Experimental Observations on Heat Transfer in Hydrogen Direct Reduced Iron

   University essay from KTH/Materialvetenskap

   Author : Felix Göttfert; [2023]
   Keywords : Hydrogen Direct Reduced Iron H-DRI ; Hydrogen Hot Briquetted Iron H-HBI ; Heat Transfer; Thermal Conductivity; Thermophysical Properties; Hydrogen Direct Reduced Iron H-DRI ; Hydrogen Hot Briquetted Iron H-HBI ; Värmeöverföring; Termisk konduktivitet; Termofysiska egenskaper;

   Abstract : Steel has played an indispensable role in shaping our contemporary world  and will persist to play that role for the foreseeable future. However, the steel industry currently is responsible for 7% of the global CO2-emissions, primarily due to the conventional carbon-based reduction process of iron ore. READ MORE

6. 5. Experimental Study and Modelling of Heat Transfer in Milling of Titanium Alloys

   University essay from Lunds universitet/Industriell Produktion

   Author : Belén Cámara Herrero; [2022]
   Keywords : Titanium alloys; heat transfer; milling; modelling; thermal simulation; Technology and Engineering;

   Abstract : The purpose of this project is studying heat transfer to indexable cutting tools during milling of a selection of titanium alloys, relevant to the industry. To achieve this goal, both experimental and theoretical models were contemplated to formulate the current thesis. READ MORE
