FUTURE PROJECTS

Evaluation of Energy Efficiency, Sustainable Solid Waste Management, and University Impact: Integrated Approach for Optimizing Electricity, Fuel Use, and Machine Operations

The impact of an organization entails both positive and negative roles contributions to the socioeconomic and environmental well-being of the community. As firm grows in its age and size, the importance of evaluating the impact of its corporate activities becomes inevitable so that to ensure its sustainable development goals. The vital step to be taken by an organization towards an effort of achieving a transformative effect to its community involves evaluation of the critical corporate performance parameters such as but not limited to: energy/fuel uses, pollutants emissions, waste generation, & operations sustainability. Any failure to make decisions based on an in-depth examinations of its trend in those attributes amounts to risk its development goals. I aspire to work on optimization alternatives evaluations & estimation of corporate energy use (electricity & fuel use), solid waste management, and biogas generation potential in the context of companies in Ethiopia.

Analysis & modeling of fuel flexibility in LTC diesel engines

The world seen surge in the number of vehicular proliferation due to population rise imposed with the stringent emission regulation to safeguard the climate & environment. Given multitude of expensive conventional diesel engines acquired amidst inflation already in circulation, coupled with depletion the fossil-fuel reserves & the established infrastructure, encompassing from makers & diesel oil traders to repairs shops, arises a pressing need for either gradual transition to electric vehicles or adapting engines to more efficient/less pollutant ones. Low-temperature combustion (LTC) strategies seen by plethora of researchers as the most promising diesel engines prospective to serve the purpose. Yet LTC strategies in diesel engines entail unresolved operating conditions, challenging fuel choices, complex controls/optimizations. I am to pursue a PhD focused on the analysis & modeling of fuel flexibility in diesel engines with a specific emphasis on LTC.

An Up-to-date Summarized Online Content Creation in Engineering Disciplines

The industry left academia way behind particularly in developing countries. I want to actively engage in preparation, presentation, demonstration, and facilitation of up-to-date training programs preferably online with a specific focus on equipping graduates in engineering and youths in developing countries. My goal is to empower them with market-relevant skills enabling them to adapt in both standard job market and exploit their current scenario of transition from the outdated and inefficient manual farming practice that persisted in our communities. I aspire to collaborate in imparting relevant feasible knowledge to contribute to fostering sustainable developments and improving the economic prospects.

  • Performance and Emission Analysis of Common Rail Diesel Engine with Microalgae Biodiesel
    Yenda Srinivasa Rao and Tsegaye Getachew Alenka

    Hindawi Limited
    Modern common rail diesel engines are normally optimized with commercial diesel. As a result, the engine control unit’s calibration is established to achieve the best compromise between performances and exhaust pollutants. Biodiesel has a faster combustion rate and higher combustion chamber temperature than commercial diesel, which necessitates the injection of higher fuel volumes to compensate for the lower calorific value of biodiesel compared to regular diesel. This study showed that by adjusting the mapping of the engine control unit according to the fuel utilised, it is possible to improve the emissions and performance of a common rail diesel engine running on pure Botryococcus braunii algae oil biodiesel or a blend of biodiesel and commercial diesel.
