Higher depletion rate and increasing price of fossil fuels have motivated many researchers to harness energy from the waste heat from internal combustion engines, and thus improve the overall efficiency. Among the waste heat recovery methods, the bottoming Rankine cycle is the most promising. In this technique, the recovered heat is used to produce additional power using turbine. In order to maximise the additional power production, an effective heat exchanger design is necessary. The main focus of the current research was to design heat exchangers which needed to be pancake-shaped to be retrofitted into a vehicle. The heat exchanges chosen were shell and U-tube type. CFD simulations were carried out to optimize the design of the heat exchangers and calculate the additional power that could be achievable by using this optimized pancake-shaped heat exchangers.

Heat available in the exhaust gas of a diesel engine can be an important heat source to provide additional power using separate Rankine Cycle (RC). In this current work, experiments were conducted to measure the available exhaust heat from a 40 kW diesel engine generator set. Performance of an available shell and tube heat exchanger using water as the working fluid was conducted. With the available experimental data, computer simulation was carried out to optimize the design of the heat exchanger. This optimized heat exchanger was then used to estimate additional power considering actual turbine efficiency. Two heat exchangers were used for this purpose. One is used to generate vapour and the other to generate super-heated vapour. Two organic fluids namely Ammonia and HFC-134a were used in this study. The water was also used as working fluid to compare the results. The proposed heat exchanger can produce 10%, 9% and 8% additional power by using water, ammonia and HFC134a as the working fluids respectively.
