dc.description.abstractThe current global warming situation and various other environmental challenges call for innovative and easy-to-implement technologies to help counter the effect. One of the ways is to increase the efficiency of already existing systems to help push out more work for the same amount of energy input. In some internal combustion engines, roughly 30% of the input energy could be lost in the exhaust gases with an additional 30% wasted as heat. This wasted energy can be partly recovered using waste heat recovery(WHR) technologies. The recovered energy is then converted to electrical or mechanical energy for further use. The aim of the project is to study the feasibility of waste heat recovery in a Volvo D13 diesel engine with respect to fuel consumption using an organic Rankine cycle for marine and power generation applications. The project also includes brief evaluation of various available alternative WHR technologies. A 0D analysis was conducted using Matlab to select an appropriate working fluid based on the maximum power output and 1D simulations were done with the help of GT-Power and Matlab/Simulink. The operating points were selected based on field test data for both the applications. The 0D and 1D simulations showed that a considerable amount of energy can be recovered from both the applications. The marine and the power generation application yielded roughly 7% of the engine output power from the 1D simulations done using GT-Suite. The two applications had about 9% increase in power output from the 1D simulations done using Simulink. This increase in turn contributes to higher fuel savings hence lowering emissions in general. The 1D simulations highlighted various parameters such as pump speed and expander speed which affected the process. The results from 0D and 1D simulations were also compared for both the applications. The 1D simulations using Simulink had the highest power output and the cause of difference in the power output from other methods were discussed. From the results, it was then concluded that the inclusion of a WHR unit for the Volvo D13 engine has potential and further investigation and fine tuning of this setup will prove advantageous in helping combat the environmental challenges being faced today.sv
