Abstract

The shrinkage of the glass-alumina functionally graded materials (G-A FGMs) as a function of sintering temperature, layers, and the alumina content was predicted by a back propagation artificial neural network (BP-ANN). The BP-ANN was composed of an input layer, a hidden layer, and an output layer. 21 sets of experimental data were trained, in which the temperature, layers, and the alumina content as input parameters whereas the shrinkage as the output parameter. 5 sets of experimental data were used to identify the accuracy of the BP-ANN. From the prediction, selection of the hidden layer neurons is essential for the convergence of the BP-ANN. The minimum predicted errors less than 6.6% are obtained with 8 neurons. Comparison of the predicted shrinkage shows that the increase of layers or alumina content is beneficial to the increase of the shrinkage and expansion resistance for the G-A FGMs.

Abstract

This work applies both conventional-single-spark-discharge (CSSD) at 500-µs pulse duration time and nanosecond-repetitively-pulsed-discharge (NRPD) at various pulsed-repetitive-frequency PRF = 5–70 kHz to explore a turbulence facilitated ignition (TFI) phenomenon using a pair of pin-to-pin electrodes at an inter-electrode gap of 0.8 mm in randomly-stirred lean n-butane/air mixture with Lewis number ≫ 1. For CSSD, measured laminar and turbulent minimum ignition energies (MIE$_{L}$ and MIE$_{T}$) at 50% ignitability show that MIE$_{L}$≈ 23 mJ > the smallest MIE$_{T}$≈ 19.7 mJ at u′ = 0.9 m/s (TFI) and then MIE$_{T}$≈ 28.6/30.8/36.8 mJ at u′ = 1.4/2.1/2.8 m/s (no TFI), where u′ is the r.m.s turbulent fluctuating velocity. For comparison, all NRPD experiments apply the same total ignition energy E$_{tot}$≈ 23 mJ via a fixed train of 11 pulses, each pulse with 2.2 mJ except for the first pulse with 1 mJ. NRPD results show a cumulatively synergistic effect depending on the coherence between PRF and an inward reactant flow recirculation frequency (f$_{RC}$) inside the torus-like kernel induced by the discharge that could enhance ignition. When PRF is approximately synchronizing with f$_{RC}$, the synergistic effect is most profound at PRF = 20-kHz/40-kHz with very high ignition probability P$_{ig}$ = 90%/85% > 50% in quiescence, whereas lower values of P$_{ig}$ = 42%/34% are found at PRF = 10-kHz/60-kHz. Further, P$_{ig}$ = 0 at PRF = 5-kHz even when 5000 pulses (E$_{tot}$≈ 10 J) are applied. We discover that P$_{ig}$ decreases significantly with increasing u′ for most PRFs (no TFI) except at higher PRF ≥ 60 kHz showing possible TFI. These results are attributed to the interactions between turbulent dissipation, differential diffusion, and synergistic influence, which are substantiated by Schlieren images of initial kernel development and the ignition time determined at one half of the flame critical radius that leads to a self-sustained spherical flame propagation.
