Multiphysics Simulation of Particle-Surface Interaction and its Effect on Powder Patterns and Process Optimization
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-29)In industrial processes, powder coating is widely utilized to attain functional or aesthetic surface properties on manufactured parts. A Eulerian-Lagrangian Multiphysics solver has been developed within the OpenFOAM framework in order to simulate and optimize such processes with regards to coating efficiency and homogeneity. In the scope of this study, the powder particle-substrate and particle-particle ... -
Multiphysics Study of Infrared Thermography (IRT) Applications
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-19)The paper reviews thermographic and vibrothermography applications such as cold climate operations, determine the temperature profile of steel samples under tensile testing and perform composites Non-Destructive Testing (NDT). This review paper discusses studies, where IR thermography has been used effectively in research and development projects at the UiT The Arctic University of Norway and AGH ... -
Multiphysics study of infrared thermography (IRT) applications
(Conference object; Konferansebidrag, 2019-12)Infrared thermography is the science of detecting infrared energy emitted from an object, converting it to apparent temperature, and producing images of that radiation, called thermograms. Infrared thermography means "beyond red temperature image". IR thermography being a remote non-contact/non-destructive means of testing is perfectly suitable for tests in extreme environments. Also, it is fast, ... -
Multiphysics Study of Tensile Testing using Infrared thermography
(Journal article; Peer reviewed, 2019)In this work, the IR thermography was used to study the steel specimens (DIN 50125 Standard) undergoing the tensile tests. The tensile tests were performed using GUNT® Hamburg Universal Material Tester. The tensile specimens were clamped, and the test force was generated using a handoperated hydraulic system. A dial gauge measured the elongation of the specimens. Using the WP 300.20 system for data ... -

Semi-Implicit Method for Pressure-Linked Equations (SIMPLE) – solution in MATLAB®
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018)This work presents a method for the solution of fundamental governing equations of computational fluid dynamics (CFD) using the Semi-Implicit Method for Pressure-Linked Equations (SIMPLE) in MATLAB®. The fundamental governing equations of fluid mechanics are based on three laws of conservation, referred to as the law of conservation of mass, the law of conservation of momentum and the law of ... -
Solution of Pure Scattering Radiation Transport Equation (RTE) using Finite Difference Method (FDM) (poster)
(Conference object; Konferansebidrag, 2018)Radiative transfer is the physical phenomenon of energy transfer in the form of electromagnetic radiation. The propagation of radiation through a medium is affected by absorption, emission, and scattering. Radiative Transfer Equation (RTE) have been applied in a many subjects including atmospheric science, astrophysics, nuclear, optics, remote sensing, etc. Analytic solutions for RTE exist for simple ... -
Strain Wave Analysis in Carbon-Fiber-Reinforced Composites subjected to Drop Weight Impact Test using ANSYS®
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-11)Composite materials are becoming more popular in technological applications due to the significant weight savings and strength these materials offer compared to metallic materials. In many of these practical situations, the structures suffer from drop impact loads. Materials and structures significantly change their behavior when submitted to impact loading conditions as compared to quasi-static ... -
Study of the required thermal insulation (IREQ) of clothing using infrared imaging
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017)The sense of cold develops due to the increase in heat loss from a human body. Excessive cold can be a health hazard, since excessive heat loss from the body may result in hypothermia/frostbite. Decreased body temperature due to heat loss also affects the physical, manual and perceptive performance of individuals. Therefore, protective measures are taken through clothing that controls and regulates ... -
