Building sector is a major consumer of electricity, it is imperative to evolve building designs that would utilize solar and wind energy to the fullest possible extent for ameliorating thermal environment indoors. Architects and engineers who incorporate energy design concepts and methods into their design projects can play a significant role in reducing energy consumption and achieving sustainable energy structure for our society. Energy Conservation Building Codes (ECBC) have proven to be sources of’ lasting energy savings in new construction.
A new technological technique based on the “moist” carbon dioxide generation in the wellbore zone of the oil formations or at the wellhead is proposed. In this new technology a carbon dioxide is generated as a result of the chemical reaction between an aqueous acid solution and a natural calcium carbonate rock (limestone) as a “gas yielding” component. The mechanism of the process allows controlling a generation rate and a volume of the gas, the thermobaric conditions of the oil formation, mineral and acidity levels of water and a phase state of carbon dioxide. An industrial application of this technology in a large scale has a significant ecological importance as this technology utilizes the wastes of processing plants of the natural minerals, which is considered as a major source of the pollution of atmosphere by greenhouse gas emissions.
The main objective of this study was to experimentally investigate the use of soyabean oil methyl ester and its blends in a single cylinder direct injection compression ignition engine. The fatty acid methyl esters in soyabean methyl ester were found to be Myristic acid, Palmitic acid and Stearic acid in prominent proportions. The blending ratios of 5%, 10%, 15% and 20% of SOME with diesel were used in this study with varying loads. The combustion study such as in-cylinder, maximum peak pressure, rate of heat release and ignition delay were analyzed and found that SOME 20% blend exhibits maximum cylinder pressure and better heat release characteristics. The effect of injection timing was analyzed by advancing and retarding the injection timing by 5oCAD and found to have positive effect on combustion efficiency with advancement of injection timing.
The potential use of Limonia Acidissima hull powder for the removal of chromium (VI) from waste water has been investigated in batch mode experiments. Influence of parameters like initial chromium (VI) concentration (5-30 mg/l), pH (2-4), and biomass dosage (2-2.8 g/l) on chromium (VI) adsorption were examined using response surface methodology. The Box-Behnken Design (BBD) in response surface methodology was used for designing the experiments. The optimum conditions for maximum removal of chromium (VI) from an aqueous solution were as follows: adsorbent dosage (2.4555 g/l), pH (1.8211) and initial chromium (VI) concentration (5 mg/l). The high correlation coefficient (R2 =0.991) between the model and the experimental data showed that the model was able to predict the removal of chromium (VI) from waste water using Limonia Acidissima hull powder efficiently.
Solar energy system can be applied to directly convert sunlight to the electricity with advantages of safe, clean, quiet, and non-pollution features. Currently the solar energy system is one of the most important energy-converting systems in modern world due to the coming shortage of global natural resources. The solar systems are being continuously developed in these years but few research works have been done in computational simulation on solar tracking system design and development. This paper is to study a new solar tracking system using computer-aided modeling and analysis. The numerical simulation proposed in this paper can help to understand the systematic driving mechanism and determine the effects of some critical parameters on solar tracking system performance. The computer-aided modeling can design and modify the solar energy system quickly without trying to repeatedly make real system which can save manufacturing time and cost. To compare computational results, a prototype has been built and tested. Both computer-aided modeling and prototype testing show close results which validate the analytic methodology proposed in this research.
