Specific Action as a Metric to Determine Thermal Degradation of Conductive Fabrics Exposed to High Current Impulses

“…For the case in which these angles are presented in a section of length snw , the equivalent cross section area normal to the current flow with fibers within this angle range is given by Figure 6. Cumulative partial conductance for a non-woven fabric as a function of the fiber angles calculated using (16) for R = 0.018 Ohm andfor fiber angles with uniform probability distribution function p(ϕ f ).…”

“…(10) and (11) for woven fabrics and Eqs. (11) and (16) for non-woven fabrics. These cross-section areas and the used parameter values are presented in Table 3.…”

“…For woven fabrics, SA was calculated at the woven sections and at the contact areas between warp and weft yarns; meanwhile, for non-woven fabrics, SA was calculated using the average cross section area and the partial cross section area obtained from Eq. (16) to illustrate the case in which a section of fibers are not aligned with the current direction.A cross-section area of 0.23 mm 2 was calculated using Eq. (16) with uniformly distributed angles below |ϕ f | < 50 • and snw = 625 mm to represent the case of the sample shown in Fig.…”

Investigation and treatment of the aluminizing process for mirrors of astronomical telescopes and optical instruments of space vehicles

“…The heat absorbed due to aluminum contacted parts, which are U-shaped wires clamped to each turn of the helix in the tungsten filament, can be found by calculating the total energy Q Total required to transport the film from solid to gas through vaporization. So, after summing the main elements of energies associated with the phase changes, the total energy Q Total can be obtained as in the following equation; [14].…”
