All businesses must store goods and materials safely, especially warehouses, factories, shops, food, agricultural, and construction businesses. Leaving materials exposed reduces their overall quality; hence, certain structures are used to safely retain the materials for further use. These are called storage structures. A silo is a commonly used storage structure for the storage of bulk materials such as grain and cement. This paper deals with the design of a steel silo for the storage of pozzolana cement. A storage silo is essentially made up of a cylinder-shaped wall and a hopper bottom. Steel Silos are gaining more popularity in terms of cement storage usage. A 150-ton capacity steel silo has been designed for a seismic zone-2 [1] location in Madurai, Tamil Nadu, India (therefore omitting the inclusion of seismic loads). The preliminary design of the silo structure is carried out with the help of Indian Standard code books. Indian Standard code books such as IS 9178-Parts 1,2 & 3 (1979) were used for the basic design. Other necessary code books were used for load calculations. The plan and elevation of the Silo have been drafted by using AutoCAD. The designed Silo is analysed using STAAD Pro. The pile foundation of the Steel Silo has also been designed and analysed using STAAD Foundation.","PeriodicalId":8039,"journal":{"name":"Applied Mechanics and Materials","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140078645","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}

Automobiles pollute the air, and clean-air laws have made Catalytic Converters a legal requirement because they convert harmful pollutants from an engine's exhaust into cleaner emissions. The device works with the principle of a catalyst, something that causes or speeds up a chemical reaction without itself being changed. But the presence of a catalytic converter increases the exhaust back pressure which has an indirect effect on the engine efficiency ie engine efficiency decreases, thus increasing fuel consumption. The performance of a catalytic converter is substantially affected by the flow distribution inside the substrate, a uniform flow distribution can increase its efficiency, lower the pressure drop and optimize engine performance. The flow distribution in a catalytic converter assembly 15 is governed by the geometry configurations of the inlet and outlet cone section, the substrate, and exhaust gas compositions, and therefore a better design of the catalytic converter is very important. This Project deals with the fundamental understanding and study of complex processes taking place involving fluid flow, pressure, and velocity profiles in the catalytic converter using ANSYS WORKBENCH 2022 R1.

In this study, the liquid raw PLA photopolymer was changed by adding different contents of Ammonium Phosphate (APP), melamine cyanurate (MCA), Aluminum Tri-hydroxide (Al2O3) and Nano-silicon dioxide (SiO2) additives. The solid PLA nanocomposite specimens were printed by using DLP device according to the standard geometry for burning test UL-94 to evaluate its flame-retardant property. In addition, the printing product and residue after burning test was analyzed for their morphological characteristic by using SEM. The results showed that the low weight fraction of MCA showed excellent performance. PLA/MCA successfully kept green body form until the sintering temperature of stainless steel was achieved.

The anisotropic nature of the printed products due to the layered structure and many cavities that are present inside the printed parts are among the main causes of this problem. In this study, the powder addition reinforcement (PAR) method had been developed by introducing reinforcing powder into the polylactic acid (PLA) as the base material during the printing process so that nozzle clogging can be avoided and powders can be placed between the layers. In this work, iron oxide nanoparticles (Fe2O3) were used as a reinforcing powder. The addition of this powder was carried out by using two methods, namely brushing and compressed air-assisted techniques. The results showed that the compressed-air assisted technique demonstrated better results in terms of mechanical properties. In this case, the tensile strength of the composite with the compressed-air assisted technique was higher by 28.95% than that of the PLA and by 5.53% - 25.2% than that of the brushing method. Finally, this study showed that the compressed air-assisted method is the potential to be developed in the future as a powder addition reinforcement technique in the FFF process.","PeriodicalId":8039,"journal":{"name":"Applied Mechanics and Materials","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140079363","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}

Generally, NMC is processed from high-quality ore (sulfide ore) to produce nickel (II) sulfate hexahydrate or NiSO4.6H2O. But sulfide ore face scarcity due to a long history of mining and exploitation. Thus, laterite-type nickel ore can be an alternative to nickel resources. This study aims to produce mixed sulfate precipitates from a ferronickel leaching solution that can be utilized further to produce NiSO4.6H2O. Also, this research will study the pH effect of the precipitation process on the product's elemental composition, recovery, and compounds formed. The precipitation process was conducted using 5% MgO (weight basis) with a pH range of 2.5 to 6.5 with one increment. The mixed sulfate precipitates were characterized using AAS, EDX, and XRD. When using a pH of 3.5, a nickel concentration of 1473.00 ppm, nickel recovery of 23.02%, and Nickel grade of 3.18% could be obtained. As a result, the phase of NiSO4.6H2O was formed.

A new engineer to be equipped with the know-how of an OP (Operational Procedure) of machinery, this virtual laboratory helps to know the intricate details of the machinery and tools. The virtual laboratory combines the use of MR technologies, such as augmented reality (AR) and virtual reality (VR), with advanced 3D modeling tools. This virtual laboratory has the potential to revolutionize the sustainable design process by providing an immersive and flexible platform for experimentation, analysis, and collaboration. This project focuses on helping the user to visualize the machine (i.e., Single Drum Piston) and its functionalities through an immersive experience and understand the visual empathy of it. Through 3D Modelling technology, Plane detection and algorithms written with C# script we built this solution with the incorporation of Autodesk Maya and Unity Game Engine. The built solution can be experienced immersive by viewing it through a mobile placed in a headset (Aryzon Headset). This MR experience provides realistic virtual presentations which eases learning of complex modules while analytics ensure understanding of outcomes. It can empower designers and researchers to explore innovative design solutions, optimize resource utilization, and ultimately contribute to the development of more sustainable built environments. This can be incorporated in various other fields like automobile manufacturing, machine industries, construction tool manufacturing, real estate buildings & landscapes, home appliances and furniture, interior design, medical institution, and educational institutions.","PeriodicalId":8039,"journal":{"name":"Applied Mechanics and Materials","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140263604","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}
