5 giorni fa · Figure 13 shows the thickness and dimensionless pressure of the floating ring seal air film for a smooth surface and fractal rough surfaces with fractal dimensions D = 2.5 and D = 2.6, respectively. It can be seen that the surface roughness is presented in the air film thickness, which is more pronounced when the fractal dimension D = 2.5.
4 giorni fa · In the case of PEG-2k, the surface film exhibited the most heterogeneous structure throughout the compression period, owing to the numerous bands visible over the whole range of surface pressures. This may stem from the higher amount of CTAB present in the aqueous subphase because, according to our previous studies, the Au-NRs monolayer became more homogeneous with increasing surface pressure.
3 giorni fa · The 9K32 Strela-2 ( Russian: Cтрела, lit. 'Arrow'; NATO reporting name SA-7 Grail) is a light-weight, shoulder-fired, surface-to-air missile or MANPADS system. It is designed to target aircraft at low altitudes with passive infrared-homing guidance and destroy them with a high-explosive warhead .
4 giorni fa · The film is based on a Diaphragm (Silicon nitride), and the piezo layer (AlN) is deposited on it. For the piezo layer, I apply "terminal" boundry condition (V=0) at top surface and specifying the bottom surface as "ground". The "Bundary load" condition of Harmonic Perputation (Pressure = 1Pa) is at the bottom surface of diaphragm.

4 giorni fa · If you end up using a window film, you’ll want to make sure the rest of your window is taken care of. Pay special attention to the gaps between your window and the window frame. This is where most of the air is likely coming from, and if there’s air, there’s sound. However, that’s easy enough to take care of.
