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 ...

Study of Wind Chill Factor using Infrared Imaging
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-29)
This paper presents a study of wind chill factor using infrared imaging. Wind chill factor is the cooling sensation due to the exposure of wind temperature environment. The wind chill factor depends on air temperature, wind velocity, and humidity. Wind chill poses serious health risks. Various wind chill index models are given in the literature. The wind chill factor is closely associated with the ...
Determination of Thermal Properties of Fresh Water and Sea Water Ice using Multiphysics Analysis
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-29)
This paper presents a methodology to determine the thermal conductivity of ice using multiphysics analysis. This methodology used a combination of both experimentation and numerical simulation. In the experimental work, an ice block is observed using an infrared camera. The results reveal the variation in temperature over the surface. These results are dependent on two primary heat transfer parameters, ...
Review of the Phenomenon of Ice Shedding from Wind Turbine Blades
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-29)
Wind power is a sustainable source of energy. However, there are certain challenges to be overcome. One of the operational challenges is the phenomenon of ice shedding. Icing happens on wind turbine blades in cold regions. When ice grows to a certain size, it separates from the wind turbine blades resulting in the phenomenon of ice shedding. This phenomenon is of significantly dangerous for equipment ...

Investigation of Ice-PVC separation under Flexural Loading using FEM Analysis
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-29)
This paper presents the FEM technique applied in the study of ice separation over a polyvinyl chloride (PVC) surface. A two layer model of ice and PVC is analysed theoretically using Euler-Bernoulli beam theory and the rule of mixtures. The physical samples are prepared by freezing ice over the PVC surfaces. The samples are tested experimentally in a four-point loading setup. The experimental results ...
