2. 1. LES stochastic modelling of cavitation with its applications in OpenFOAM

   Author : Boxiong Chen; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rayleigh-Plesset Equation; Cavitation; Modelling; Simulation; Eulerian Stochastic Field Method; OpenFOAM; Homogeneous Equilibrium Model;

   Abstract : Cavitation is a vaporization process that commonly happens in high-pressure injector nozzles nowadays. It has been shown by previous studies that cavitation has a significant influence on the subsequent atomization process, the quality of which would in turn heavily affect the process of combustion.

4. 2. Reliable Information Exchange in IIoT : Investigation into the Role of Data and Data-Driven Modelling

   Author : Mehrzad Lavassani; Tingting Zhang; Mikael Gidlund; Ulf Jennehag; Christer Åhlund; Mittuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Internet of Things; Industrial Automation; Data Analytics; Data-Driven Modelling; Distributed Modelling; Industrial Wireless Sensor Networks; Wireless Sensor Networks; Industrial Monitoring Framework; Reliability; Real-Time;

   Abstract : The concept of Industrial Internet of Things (IIoT) is the tangible building block for the realisation of the fourth industrial revolution. It should improve productivity, efficiency and reliability of industrial automation systems, leading to revenue growth in industrial scenarios. READ MORE

5. 3. Calibration and Modelling of Adipose Tissue Under Impact Loading

   Author : Hosein Naseri; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Constitutive modelling; Global sensitivity analysis; Adipose tissue; Finite element human body models; Obesity;

   Abstract : Vehicular injury is one of the main reasons for traumatic injuries. Finite Element HumanBody Models (FEHBM) have become very popular to assess car crashes and the subsequentinjuries. It provides the possibility to predict stress and strain values in tissue level byrepresenting anatomical structures in details. READ MORE

6. 4. Automatic and Explicit Parallelization Approaches for Equation Based Mathematical Modeling and Simulation

   Author : Mahder Gebremedhin; Peter Fritzson; Erwin Laure; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Modelling; Simulation; Multi-core; Automatic Parallelization; Clustering; Scheduling; Explicit Parallelization; ParModelica; Task Systems; GPGPU;

   Abstract : The move from single-core processor systems to multi-core and manyprocessor systems comes with the requirement of implementing computations in a way that can utilize these multiple computational units efficiently. This task of writing efficient parallel algorithms will not be possible without improving programming languages and compilers to provide the supporting mechanisms. READ MORE

7. 5. Thermal Conductivity of Cast Iron: Influences of Microstructure on the Thermal Conductivity of Cast Iron

   Author : Daniel Holmgren; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EBSD; Laser Flash Technique; Modelling; Spheroidal Graphite; Lamellar Graphite; Primary Austenite; Compacted Graphite; Pearlite; Ferrite; Thermal Conductivity;

   Abstract : The thermal transport properties of cast iron are important in high temperature applications,where the temperatures should be kept low and the thermal gradients within the componentsmall. Dimensional and microstructural changes, thermally induced stresses and even failuremight be catastrophic consequences of intense and/or unevenly distributed temperatures. READ MORE
