In order to verify the evenness of the air distribution, several tools can be used. Firstly, a simulation can be carried out to check each iteration of the design. From Figure 16, as well as the table above, it can be seen that the simulations have produced desirable results of similar flow rates and air velocities for both the front and rear cylinders, as well as even pressure distribution when the flow occurs. Flow simulations are discussed further in Chapter 4.
