Energy Conversion System

(a) Determine the non-dimensional expressions and . [8 marks] Solution: There are 6 variables involved in the problem: velocity , density , viscosity , surface tension , diameter is and acceleration . Choose the three recurring variables: velocity , density and diameter . From Buckingham pi theorem we have non-dimensional groups. The choice of velocity , density and diameter as the repeating variables satisfies: They are measurable, good design parameters and in combination, contain all the dimension and . We form the three groups according to the 2nd theorem. As the groups are all dimensionless, there must have dimensions such as: , we can use the principle of dimensional homogeneity to equate the dimensions for each group. For the first group, In terms of dimensions, we have that: Thus, we have the following linear system: For For For The solutions for is given as: Giving as And a similar procedure is followed for the other groups. ...

Energy needs in Australia
People light and heat their houses using energy. People also cook their meals using fuel. The cars, planes, or trains that people use to get to their respective workplaces require energy. Therefore, in essence, energy forms an integral part of our lives. It is the main driver of a country’s economy. Over the years, fossil fuels have been widely used. Perhaps the oldest form of fuel used is wood. During the industrial revolution, coal was used in industries, and in steam ships. Oil and gas have probably been the most depended on forms of energy sources in the world today. Most economies are…

Solar renewable energy
Electricity generation contributes around 19% of the share of renewable out of which hydroelectricity contributes 16% and the remaining 3% comes from new renewable. Solar energy is the energy that comes from the sun in the solar radiation form which is used in heating or generation of electricity. To generate electricity using solar powered electricity generation system, one requires using photovoltaic or heat engines known as concentrated solar power. Some of the most common solar applications include solar cooling using solar architecture, lighting, heating of the space, solar cooking, high…

Making Solar Energy Economical
The demand for energy is dependent on properties of conversion means, technologies, and costs. Human energy makes use of resources that can be depleted in particular fossil fuels derived from the preferences. Market forces and cartels may guide a transition back to sources that are renewable. Energy as such has its effects and they come in terms of very heavy environmental costs. At the end of it they are incorporated into the energy cost and prices leading to overuse of energy and motivate policy inventions. Focusing on human utilization of the energy commodities and energy resources and the…
How to Use Gold in Wind Turbine
This explains the re-emergence of wind power as a green and sustainable source of energy. The argument behind the re-emergence of wind powers source of energy cannot only be looked at in the context of milling rain or pumping of water as was the case in the past, but is all about the energy needs that have grown due to globalization and industrialization (Schmid and Klein 1990, p.17). Wind power is generally harnessed from wind in motion, which is transformed into energy with the help of a wind turbine. Blaabjerg and Chen (2006 p.1) note that wind turbine has been one of the fastest growing…

Alternative Energy
Its biggest advantage is that it is virtually maintenance free and absolutely reliable, because of the absence of moving parts; it is designed for ease of assembly, use and maintenance. Its yet another significant benefit is that, it offers an option for nations to rid themselves of avoidable dependence on oil for fulfilling their gross energy needs. It is a nascent technology possessing the long term potential to create additional jobs for strengthening of economies. It does not generate hazardous waste or cause atmospheric pollution by release of gases like carbon dioxide, sulphur dioxide,…

How to use a Gold in Wind Turbines
One of the ways of embracing the sustainable activities is through employing wind power in the production of electric energy instead of using fossil fuels to produce electricity (Jamieson 2012). The gadget that converts wind energy to electric energy is wind turbine. The use of wind turbine to produce electricity has been in existence for some time now. However, it was not until people realized that other sources of energy such as fossil fuel and nuclear energy among others degrade environment that wind turbine was widely used to produce electricity (Mathew & Philip 2011). Basically, wind…

Pelamis (Wave energy system)
Generally, offshore devices have the lowest potential impact1. Wave energy is also not expensive to maintain and operate. It guarantees 100% available technology and when complete, it can serve a high demand of electricity. It is also tuneable, power smoothing and has maximum site flexibility. The converter can be maintained off site and has minimum work on site. It is also almost invisible to large hydrodynamic effects, making it strong on survivability. The converter is also a great relief to the impending exhaustion and reduced reserves of fossil fuels, and the geopolitical issues related…
