The characteristics described above can be increased further by employing aluminium matrix composite materials reinforced with harder particles. The hybrid aluminium alloy (Al7075) composite was made in an electric resistance furnace using the sand mould process and reinforced with alumina (Al2O3) and boron carbide (B4C) particles. The purpose of this research to investigate the mechanical characteristics of Al7075-Al2O3-B4C hybrid composites with stable Al2O3 weight percentages (4%) and varied B4C weight percentages (2–6%). Mechanical characteristics includes tensile and compressive strength, hardness, and microstructure analysis were evaluated on the pure and cast specimens. In this study, which followed the ASTM standard, the mechanical characteristics of Al7075 alloy hybrid composites were examined experimentally and validated using FEA. The results showed that when hard ceramic particles (Al2O3/B4C) were added to matrix alloy (Al7075), mechanical characteristics such as compressive strength and hardness improved while tensile strength was reduced. The static structural tensile test was successfully simulated in ANSYS. It was observed that both FEA results and analytical results were correlated.KEYWORDS: Al7075Al2O3, B4CmicrostructureMechanical behaviourFEM Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementThe data that support the findings of this study are available from the corresponding author, upon reasonable request.Additional informationNotes on contributorsJ KumaraswamyDr. Kumaraswamy J is currently working as an Assistant Professor in the Dept. of Mechanical Engineering at R.

But however, lack of inclusive material characterisation outcomes drives the need to bridge this research gap. In this study, erythritol was subjected to both chemical and thermal characterisation investigations. X-ray diffractometry (XRD) investigation estimated the degree of crystallinity to be 73.48% and the crystallite size to be 38.79 nm. The fourier transform infrared spectroscopy (FT-IR) investigation has identified -OH, -C-H and -CH2 to be the major functional groups. The scanning electron microscopy (SEM) investigation visualised the crystalline architecture of the PCM. The energy dispersive x-ray spectroscopy (EDAX) investigation quantified the composition of C and O in the eclectic constituency. The UV-visible spectrophotometry investigations confirmed that erythritol could be utilised for direct solar thermal applications. The thermal characterisation investigations rendered the latent heat of the PCM to be 333.48 kJ kg−1 and its peak melting temperature to be 118.18°C. The thermal stability investigations estimated the latent heat loss per cycle to be 1.1451 kJ kg−1.KEYWORDS: Characterisationphase change materialsthermal energy storage Nomenclature β=Full width at half maximum (FWHM) (radians)λ=Wave-length of x-ray (Å)ρ=Bulk density of erythritol (kg m−3)ρxr=X-ray density of erythritol (kg m−3)θ=Peak location (radians)Ag=Avagadro’s constant (or) Avagadro’s number: 6.02214076 × 10 23Cpl=Liquid phase specific heat (kJ kg−1 K)Cps=Solid phase specific heat (kJ kg−1 K)hm=Latent heat of fusion (kJ kg−1)M=Molecular weight of erythritol (g mol−1)Qm=Heat energy required for melting alone (kJ)Qls=Heat energy stored during liquid sensible heating (kJ)Qss=Heat energy stored during solid sensible heating (kJ)Tamb=Ambient temperature (K)Tpm=Peak melting temperature (K)V=Volume of the unit cell (m3)A=Absorbance (%)D=crystallite size (nm)K=Scherrer equation constantm=Mass of erythritol used (kg)Q(t)=Instantaneous heat energy stored (kJ)R=Reflectance (%)T=Transmittance (%)AcknowledgementsThe authors thank the Department of Science and Technology (DST), Government of India and the management of PSG College of Technology, Coimbatore for their financial support.Disclosure statementNo potential conflict of interest was reported by the authors.Additional informationFundingThis work was supported by the Department of Science and Technology (DST), Government of India under Grant No.: DST/TMD/MES/2K16/20(G).Notes on contributorsPaul Gregory FelixPaul Gregory Felix holds a doctoral degree in Energy Engineering.

The purpose of this study is to propose a practical model for a compound parabolic trough solar thermal reactor for pyrolysis of waste plastic. The model integrates predictions of energy available from solar radiation (at a given location, time of day and time of year) with parabolic trough collector orientation and efficiency, a transient energy balance for an evacuated tube reactor and pyrolysis kinetics of waste plastic. The experimental setup used to test the model includes a pyranometer, a commercial solar collector consisting of a 60 cm long evacuated tube with a compound parabolic reflector and multi-channel data loggers to collect temperature, humidity and radiation data. The solar radiation sub-model was found to be in excellent agreement with clear-sky irradiance data collected using the pyranometer. Predictions of reactor temperature and reaction rate were found to be sensitive to the concentrator aperture area, solar irradiance, type of plastic (Arrhenius kinetics) and radiation properties of the evacuated tube reactor but relatively insensitive to humidity, wind velocity and terrestrial irradiance. The model shows that even on a small scale, favourable conditions for pyrolysis of waste plastic can be achieved within a solar reactor.","PeriodicalId":8584,"journal":{"name":"Australian Journal of Mechanical Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136019328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One way to overcome this difficulty is continuous liquid interface production (CLIP), which has enabled the mass manufacture of polymer components through continuous printing. Due to a limitation in access to this system, different oxygen gas permeable windows composed of polydimethylsiloxane polymer with variable substrate shapes were introduced and evaluated in this research. The aim of this study is to improve the printing speed of porous components in a layerless uniform 3D printing system as compared to Digital light processing (DLP). The results of these experiments show that the island container, compared to the micro-channel container, has a 107% increase in the duration of continuous printing before the separation force begins, enhances the component’s look, increases the height of the printed part by 30%, and decreases the maximum separation force by 7.4 times.KEYWORDS: Additive manufacturingcontinuous liquid interface productionoxygen control zonelayerless uniform 3D printing Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementThe data that support the findings of this study are available from the corresponding author, M.Salehi, upon reasonable request.Additional informationNotes on contributorsMohammad SalehiMohammad Salehi, is a master’s student in the Mechanical Engineering Department at the University of KNTU, Tehran, Iran.
