WitrynaHowever, limited research has focused on wall-impinging spray behavior, particularly adhesive features after impingement. Si et al. investigated the features of the impinging spray from macroscopic and microscopic perspectives, and compared the spray shape before and after the fuel impinging on the wall, and the droplet size and velocity. As … Witryna24 cze 2024 · A droplet in oblique impact is subject to a combination of downward motion along the surface with a tangential impinging velocity of v 0 sinϕ and motion normal to the surface with an impinging velocity of v 0 cosϕ, where v 0 is the impact velocity and ϕ is the tilt angle of the surface. The downward motion promotes the drop to move … Witryna9 lut 2024 · Moreover, it can be observed that the axial velocity of the jet fluid is higher when applying external magnetic field. The maximum velocity value is 155 m/s when exerting current of 1.5 A on the coil. Moreover, the velocity attenuation along the flowing direction due to the jet diffusion is restrained.
