    An efficient exhaust system is vital to maximising the performance of an internal combustion engine (ICE), hence improving overall vehicle performance. To have an efficient exhaust system, the amount of exhaust backpressure is to be minimised. To decrease the backpressure effects in the exhaust system, the exhaust has to be redesigned according to the certain bending radius, length of straight pipe and bending angle and pipe diameter. This paper presents design and analysis of the exhaust system used in Shell Eco-Marathon 2019 competition. In this project, the exhaust manifold was redesigned according to the specification of the chassis, the exhaust outlet in the engine and the rules and regulations of the competition. Computational Fluid Dynamic (CFD) analysis was employed to identify the optimum exhaust system design with minimum pressure loss. Among the tested models, the exhaust manifold with 100 mm length, 30° bending angle, 34 mm diameter, and 40 mm bending radius was the optimised design that resulted in the lowest pressure loss of 12.24 kPa. This study shows that a small bending angle with a short straight pipe has led to a smoother exhaust flow and even exhaust velocity across the model.

    This paper presents the parametric studies conducted on a packed-bed phase change material (PCM) encapsulated in spheres using the effectiveness-number of transfer units (ɛ-NTU) method for optimisation purposes. In order to maximise the energy storage effectiveness within a packed-bed PCM system, the numerical study on the impact of different parameters was implemented by varying the length (L) and radius (R) of the TES tank, number of spheres (n1) in the tank, and sphere diameter (r3) while maintaining the compactness factor (γ) within the range of 0.3442 ± 0.02 m. The modified charging efficiency (ε*) of the PCM and the modified energy storage effectiveness (α*) of the tested configurations were calculated and compared. As a result, the ‘optimum design’ of the tank yielding the maximum energy storage effectiveness was identified at the optimum length and radius of 1.42 and 0.475 m, respectively, filled with 4098 PCM spheres. The study found that a low L/R value resulted in higher phase-change effectiveness, and the storage effectiveness was maximised at an optimum sphere diameter of 0.03475 m. The investigation led to the conclusion that by concurrently modifying L, R, and n1 during the charging process was advantageous in increasing the heat transfer surface area using small balls, reducing the mass flow rates, and utilising spheres with small diameters.
