Diesel Fuel Injector Nozzles
2020-9-3 · The impact of nozzle hole inlet rounding on nozzle performance is illustrated in Figure 16 where the effect of different nozzle hole inlet chamfer radius (r c) is simulated [2208]. In this example, the baseline case with no rounding of the nozzle inlet shows a C d of about 0.75 at low pressure (i.e., low flow rate) and about 0.64 at 100 MPa.
