  • A one-dimensional momentum conservation equation for a straight jet driven by an electrical field was developed. It was presented in terms of the stress component, which could be applied to any constitutive relation of fluids, and the only assumption was that the fluid was incompressible. Our results indicated that both the axial and the radial constitutive relations were required to close the governing equations of the straight charged jet. However, when the trace of the extra stress tensor was zero, only the axial constitutive relation was required. It was also found that the second normal stress difference for the charged jet was always zero. A comparison with other developed momentum equations was made.
