Web7 Aug 2024 · We report an experimental study on the flow and heat transfer for a single microhole of water spray impingement on an indium tin oxide (ITO) heating plate using a piezoelectric atomizer. A microhole of dj = 35 µm was used and tested with a volumetric flow rate of 0.22 cm3/min for three different spray heights of 10, 20 and 30 mm and five … Web1 Apr 2024 · In this study, high-speed liquid fuel jets from a single-hole GDI injector were studied. The nozzle diameter of the injector was 0.14 mm, and the nozzle length was 0.20 mm. The test parameters used in the study are tabulated in Table 1. N-heptane was used as the test fuel, and the commanded pulse width of the injector was constant at 1.5 ms. aldi ephrata

Web15 Nov 2024 · The single-hole injector employed in the present study was modified from a commercial 6-hole GDI injector and 7 MPa injection pressure with 3 ms injection pulse was used. A low injection frequency of 0.25 Hz was adopted to make the measurement area clear before next injection. WebThis spray is spread out finely into an approximate 15-30 degree fan. The multi-hole design does not incorporate a pintle-orifice configuration but instead, a series of orifices drilled out at angles which create a similar cone spray when fuel flows through the holes. Other injectors such as the type once manufactured by Lucas Automotive ... WebThe fuel spray test bench is shown in Figure 1.
