Figure 5. Simulation results for two types of printing needles. Cylindrical nozzle: (A) volumetric flow rate at the nozzle tip versus dispensing pressure,
(B) area-weighted outlet average velocity, and (C) velocity profiles across the radius. Conical nozzle: (D) flow rate versus applied pressure, (E) area-
weighted outlet average velocity under varying inlet pressures, and (F) the radial velocity distribution for various nozzle sizes. (G, H, I) Cylindrical and
(J, K, L) conical nozzle velocity contour plots at 1 bar inlet pressure and different outlet diameters: (G, J) 0.25mm, (H, K) 0.61mm, (I) 1.00mm, and
(L) 1.20mm for conical needle.
