The Spatial Arrangement of The Electric Field in the Needle-Plate Electrospinning
Indonesian Journal of Applied Physics, 2023 The electric field distribution of the Neddle-Plate (NP) electrospinning set up has reported due to the simple classical electrodynamics solutions. The charge is assumed to distribute uniformly in the needle (nozzle) and the collector (plate).

Analysis of a Jet Pump Performance under Different Primary Nozzle Positions and Inlet Pressures using two Approaches: One Dimensional Analytical Model and Three Dimensional CFD Simulations [PDF]
Journal of Applied and Computational Mechanics, 2020 A jet pump operates under the Venturi effect, where a fluid enters through a primary nozzle and, when passing through a convergent-divergent nozzle, it reaches supersonic conditions, originating a vacuum pressure in a secondary fluid.

Nonlinear Dynamics of Adaptive Gun Head Jet System of Fire-Fighting Monitor
IEEE Access, 2020 The working medium of the adaptive gun head jet system of fire-fighting monitor is generally water containing a little bit of air. During the operation, the pressure pulsation of the fluid will cause the fluctuation of the equivalent stiffness of the gas-

Noncoalescence in the Oblique Collision of Fluid Jets [PDF]
Physical Review Letters, 2013 When two jets of fluid collide, they can "bounce" off each other, due to a thin film of air which keeps them separated. We describe the phenomenon of stable noncoalescence between two jets of the same fluid, colliding obliquely with each other. Using a simple experimental setup, we carry out a parametric study of the bouncing jets by varying the jet ...
