Design, Simulation, Construction And Performance Evaluation Of A Solar Oven

Abstract

A solar ovenis a device that converts solar energy into useful heat in a confined space( roaster chamber) which can be utilised for cuisine and bakingpurposes.The roaster consists of aeroplane mirrors to concentrate the solar radiation on thecollector.The heat gain is maximum if the collector and mirrors are continuously acclimated similar that the prevalence angle of the reflected and direct radiations are minimised. In practise, it’s always delicate to manually track the movement of the sun and the use of trackers can be veritably precious. As similar, an logical model was developed to estimate the optimum yearly collector and glass tilts for maximum affair hen employing the single axis tracking mode. The operation of the different factors of the roaster was modelled using TRNSYS, Microsoft Excel and EES programs alongside solar data for Zaria. Optimisation of the design was carried out grounded onweather conditions current on the average day of the design month i.e. the month with the least solar radiation. The cock angles of collector and mirrors needed for the optimum collection of solar irradiation for each month were attained from the simulation results of the roaster model carried out for 12 months of the time. The optimum collector area and sequestration consistence were also attained through parametric studies by varying the forenamed parameters until a recession temperature of 100ᵒC was attained for the average day of the design month. The simulation results for the design with different collector areas and sequestration consistence show that an area of0.49 m2 and consistence of0.12 m yields a recession temperature of 100ᵒC. still, the recession temperature achieved was asleep to larger values of the design parameters.

Preface

Background

Energy is the focal point of all mortal conditioning; it’s the base of artificial civilization. Without energy, ultramodern life would cease to live. In the history, the demand for energy sources was minimum because it was primarily used for cuisine and original product. But as time went on, population increase and technological advancement led to further demand for energy. The major sources of energy are the conventional sources, which include fossil energies, and nuclear energies. reactionary energies, which include petroleum, coal, and natural gas, give utmost of the energy need of ultramodern artificial society. Other uses are set up in the transportation, domestic heating, and electric- power generation. Nuclear energies are used to induce electricity, but it’s utilised substantially in the developed countries due to high position of supervision and conservation needed. Thenon-conventional( renewable) sources of energy include hydroelectric power, solar energy, wind energy, biomass, ocean thermal energy, tidal energy, and geothermal energy, but the eventuality of these sources is still underutilised because they’re much more precious to harness than energy deduced from fossil energies. Hydroelectric power requires a large capital investment, so it’s frequently uneconomical for a region where coal or oil painting is cheap. As similar, they contribute a little chance to the massive energy demand of the world population. still, the fear of reduction of fossil energies due to the fast rate of consumption has provoked farther development of these indispensable energy sources, similar as solar energy.
