Analytical and Case Studies of a Sandwich Structure using Euler-Bernoulli Beam Equation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-11)
This paper presents analytical and case studies of sandwich structures. In this study, the Euler-Bernoulli beam equation is solved analytically for a four-point bending problem. Appropriate initial and boundary conditions are specified to enclose the problem. In addition, the balance coefficient is calculated and the Rule of Mixtures is applied. The focus of this study is to determine the effective ...
Applicability Extent of 2-D Heat Equation for Numerical Analysis of a Multiphysics Problem
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-01)
This work focuses on thermal problems, solvable using the heat equation. The fundamental question being answered here is: what are the limits of the dimensions that will allow a 3-D thermal problem to be accurately modelled using a 2-D Heat Equation? The presented work solves 2-D and 3-D heat equations using the Finite Difference Method, also known as the Forward-Time Central-Space (FTCS) method, ...
CFD-DEM and Experimental Study of Bubbling in a Fluidized Bed
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-12)
In this study, phenomenon of bubbling is investigated using CFD-DEM and
experiments. A CFD-DEM simulation is setup to model the fluidized beds of different
sizes. Geldart D particles of 1.2 mm diameter and 1000 Kg/m3 density are modelled. Study revealed different types of fluidization regimes as stated in the literature. An experimental setup is built to obtain the results for the comparison. ...
Finite element analysis of human femur bone
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-08-04)
An effort is made to analyse the stresses experienced by the human femur.
In order to achieve these results a CAD model was developed by using the
3-D scanning of generic human femur for an individual of 70 kg weight
(approx. averaged adult weight). The marrow cavity has been
approximated as a hollow cylinder. The FEM model was built using solid
tetrahedral element (20-noded 186 structural ...

Shock Tube. Detail overview of equipment and instruments in the shock tube experimental setup
(Book; Bok, 2015)
The shock tube is a device in which a normal shock wave is produced by the interaction of fluids at significantly high-pressure difference. The shock tube is comprised of two sections known as driver and driven sections. These two sections are interacted with the high-speed valve or a bursting disc. When the interaction happens, a shock wave forms almost instantaneously and propagates into the driven ...
Study of Acoustics Properties of SK One Component Polyurethane and its Application in Arctic Marine Structures
(Conference object; Konferansebidrag, 2016-12-08)
Marine noise reduction tends to be challenging and requires a comprehensive engineering approach. The soundproofing materials for marine noise reduction are usually exposed to high temperatures, potential fluid or oil spills, engine maintenance and a high airflow environment. This work looks into the acoustic proofing properties of a non-toxic material ‘SK One Component Polyurethane’ developed by ...
Computational Fluid Dynamic Analysis of the Tesla Valve
(Conference object; Konferansebidrag, 2016-12-08)
Serbian-born inventor Nikola Tesla invented the Tesla valve (Tesla's Valvular Conduit) and patented it in 1919. The Tesla valve is unique in the sense that it does not have any moving parts, but it can work as a one-way valve. Nikola Tesla invented this unit without advanced mathematical models, nor with the help of modern computing power. The original Tesla valve consisted of a set of cavities and ...
Improving Mechanical Grip of Tyres on Snow and Icy Road Surfaces using Finite Element Method
(Conference object; Konferansebidrag, 2016)
Harsh winter conditions are known to be one of the most challenging environments for driving. Although the number of fatal accidents is higher during the summer compared to the winter in Norway (according to Norwegian Highways Authority), the total number of accidents is higher in the winter season. These accidents mainly happen due to loss traction on snowy or icy road surfaces. The loss of traction ...
