Read More ... Metal Matrix Composite (MCC) reveals considerably better properties, such as low density, high tensile strength, hardness, and good resistance to wear compared with every alloy or other metal. The current study concentrated upon the assessment of the properties of aluminum matrix composites (AMCs) synthesis with the Al-7075 as a matrix and the MSGNPs that sieved to (35 nm) at different weight fractions percentages as reinforcements using stir-casting method and compared with Al7075/B4C-WC nanocomposites. These experiments aim to select the appropriate type and percentage of reinforcement particles for producing Al-7075 composites with the best mechanical properties. The mechanical properties, as well as the metallurgical features for analyzing the microstructure and the distribution of (MSGNP, SiC-WC) into the composite alloy specimens, have been studied utilizing the mechanical tests and the Optical Microscopy (OM), Scanning Electron Microscope (SEM), Energy Dispersive Spectroscopy (EDS), and X-Ray Diffraction (XRD) SEM pictures. By reviewing the mechanical test results, they manifested that the value of the composite's ultimate strength was enhanced with the additive concentration of nanoglass. The maximum tensile strength was obtained for the sample comprising 4% MSGNP—the composite with 6 wt.% B4C and WC have the highest hardness value, which means the increase of the added composite material beyond 10% will decrease the hardness. The X-ray diffraction (XRD) examination results illustrate the various phases of the two-theta value-generated diffraction patterns for the Al-7075/MSGNP and Al-7075/B4C-WC workpieces materials. These examinations show that the matrix of Al and the clear glass are the two major composite constituents and contain B4C, WC, and aluminum matrix, which are consistent with what was shown by the optical microstructure of the composite. The Al-7075 microstructure analysis also demonstrated a virtuous metallic bonding between the particles of Al and the uniformly dispersed and transparent glass particles at the optimal addition of 8wt%. Such enhancement was ascribed to the reinforcement's sufficiency and the uniform dispersion of MSGNP. Therefore, the addition of 8 wt.% was chosen in the present work.

Read More ... This research work presents a gas turbine performance investigation. Researchers have put efforts into this field of study; however, the influence of the concurrence of variable inlet guide vane (VIGV) drift, fouling, and erosion on the three-shaft gas turbine’s performance during part-load operation has remained unexplored. Therefore, this study addresses this gap. First the gas turbine design point and off-design performance model have been developed by utilizing the original engine manufacturer data provided. The accuracy of the models was validated, and the maximum mean absolute percentage error of the design point performance model is shown at exhaust temperature prediction, it is about 1.74%. The off-design performance model was also validated with the power output versus ambient temperature and efficiency versus operating curves. At each operational point, the power output versus ambient temperature error from the validation data was 0.02%, while the efficiency versus ambient temperature error was 4.5%. After the validation, the engine model was subjected to the concurrence of variable inlet guide vane drift, fouling, and erosion conditions to simulate the degradation state. The results show that the highest isentropic efficiency deviation due to component faults occurred in the upstream components, specifically in the low-pressure compressor’s (LPC) isentropic efficiency. The deviation recorded due to the concurrence of VIGV drift at -6.5° and 100% fouling severity is -11.47%, whereas 9.65% is the LPC isentropic efficiency deviation recorded when VIGV drift at -6.5° and erosion at 100% severity level simultaneously occurred. In addition, the effects of the faults above on gas path measurements were simulated, and the highest measurement deviation was observed when simultaneous LPC fouling and -6.5% VIGV drift occurred. Among the measurements, the highest deviation was observed in the exhaust temperature and thermal efficiency, about 9.23% and -7.35%, respectively.
