Fluid Flow
Published in O.P. Gupta, Finite and Boundary Element Methods in Engineering, 2022
Development of high power engines (power > 250 kW) for heavy-duty trucks demands considerable heat removal for efficient cooling. Aoyagi et al. [15] reported such analysis for a V8 engine with cylinder bore of 139 mm and stroke 142 mm. All the eight cylinders were cooled by water flowing through the passage created between the cylinder cavity in the engine block and the cylinder liner fitted in it. One such cylinder is shown schematically in Fig. 8.7(a). The water passage was modelled through a large number of brick elements (cuboid) shown in Fig. 8.7(b). About 6000 nodes were used to model the whole geometry. The velocity distribution could be obtained by analyzing inviscid, incompressible steady flow discussed in Sec. 8.6. The vector plot of velocity gave the locations of stagnation zones. The magnitudes of these velocities were later used for analysis of temperature distribution within the coolant. Thus effectiveness of the cooling system was evaluated.
Power unit – engine

There is only one firing stroke for each cycle. The flywheel keeps the engine turning between firing strokes. Single-cylinder engines need a bigger flywheel in proportion to their size than those with more cylinders do. The flywheel on a large V8 engine is smaller than one on a four-cylinder engine. The flywheel's desire to keep rotating is called inertia; it is inertia of motion.

The reconfiguration process in this case consists of two stages: transitioning from the L4 engine cylinder block to the V6 engine block, and then from the V6 engine block to the V8 engine block. To simplify the description, these two phases are referred to as Phase A and Phase B, respectively, considering and not considering energy consumption.
