Temperature-distribution analysis on thermal spreader for micro-thermoelectric power generation
No full textInternational Conference on Applications and Design in Mechanical Engineering 2012 (ICADME 2012) organized by School of Mechatronic Engineering, Universiti Malaysia Perlis (UniMAP), 27th - 28th Februari 2012 at Bayview Beach Resort, Penang, Malaysia.Thermal spreader is used in micro-thermoelectric
power generating system to produce uniform temperature
distribution along the micro-combustor walls, very important for
thermoelectric cells to generate high electrical output power. In
the current work, the effects of material and thickness of thermal
spreaders and the temperature of the heat source on temperature
distribution along the surface of a thermal spreader were
experimentally investigated. The result shows that thermal
spreader made from copper produces the most uniform
temperature distribution compared with thermal spreaders made
from aluminum and zinc. The temperature uniformity of the
thermal spreader also increases as the thickness increases but
decrease as the temperature of the heat source increases
Analysis of labour market needs for engineers with enhanced knowledge in sustainable renewable energy solutions in the built environment in some Asian countries
No full textDespite the rapid growth in the uptake of renewable energy technologies, the educational profile and the skills gained at University level do not always comply with the practical needs of the organisations working in the field. Furthermore, even though the residential sector has very high potential in curbing its CO2 emissions worldwide thus meeting the challenging goals set out by the international agreements, such reduction has been limited so far. Within this context, the ‘Skybelt’ project, co-funded by the EU under the framework of the Erasmus + programme aims at enhancing in several Universities of Asia and Europe the engineering skills of students of all level for application of sustainable renewable energy solutions in the built environment. With the target of increasing the employability of graduates and the impact of the project, a survey on the labour market needs for specialists with enhanced knowledge and skills in the topic of the project has been conducted in the related Asian countries. Hence, relevant industries, labour market organisations and other stakeholders have been interviewed and the main results of this analysis is reported in the present paper. As first outcome of this activity, the obtained results have been considered in the selection of the modules to be improved according to a student centred study approach
Characterization of Banana (Musa spp.) Pseudo-Stem and Fruit-Bunch-Stem as a Potential Renewable Energy Resource
No full textBanana pseudo-stem and fruit-bunch-stem are
agricultural residues that can be used for conversion to bio-char, biooil,
and gases by using thermochemical process. The aim of this work
is to characterize banana pseudo-stem and banana fruit-bunch-stem
through proximate analysis, elemental analysis, chemical analysis,
thermo-gravimetric analysis, and heating calorific value. The ash
contents of the banana pseudo-stem and banana fruit-bunch-stem are
11.0 mf wt.% and 20.6 mf wt.%; while the carbon content of banana
pseudo-stem and fruit-bunch-stem are 37.9 mf wt.% and 35.58 mf
wt.% respectively. The molecular formulas for banana stem and
banana fruit-bunch-stem are C24H33NO26 and C19H29NO33
respectively. The measured higher heating values of banana pseudostem
and banana fruit-bunch-stem are 15.5MJ/kg and 12.7 MJ/kg
respectively. By chemical analysis, the lignin, cellulose, and
hemicellulose contents in the samples will also be presented. The
feasibility of the banana wastes to be a feedstock for thermochemical
process in comparison with other biomass will be discussed in this
paper
Characterization of Catalytic Porous Medium Using Platinum for Micro-combustion Application
No full textIn this study, catalytic alumina porous medium has been fabricated by using platinum as an active material for micro-combustion application. Platinum has been deposited onto porous medium surface via wet impregnation method. The porous medium undergoes surface modification process via wash coating method using gamma alumina (γ-Al2O3) solution, before being impregnated with platinum in order to increase the surface area. The surface morphology of porous medium entirely changes from smooth “solid-rock” into rough “sand-like” after the wash coating process. The amount of platinum deposited onto the treated porous medium is 1.66 wt.%. LPG combustion analysis shows that the combustion is successfully occur inside the catalytic porous media with overall efficiency of 71%
