Among various classifications of warmth exchangers, the main focus was shown by researchers on indirect contact type compact heat exchangers. Among them the shell and tube device belongs to fluid to fluid type heat transfer device. Main applications of shell and tube device feed device in process industries, refineries, chemical plants and power plants. Usually the analysis of shell and tube heat exchangers are divided into two parts namely shell side and tube side analysis. Shell side analysis is easy and doesn't involve much modification. Whereas the tube side analysis is complex and it's done by varying baffle design and elevation with regard to arrangements of tubes. The most disadvantage of shell and tube device is pressure drop which occur at the end of tubes. To overcome this problem, drilled cylindrical copper block has been introduced to switch the tube part through which the new fluid flows and therefore the cold fluid is circulated through the shell. With this design modification, the effectiveness, mass rate, overall heat transfer co efficient are simulated and analysed.","PeriodicalId":517869,"journal":{"name":"1, 2024","volume":"2 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140285527","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}

With its unique thermal machining technique, Wire Cut Electrical Discharge Machining (WEDM), items with sharp edges and varied hardness that prove challenging to produce using conventional machining methods can be precisely machined. Utilizing the widely used non-contact material removal technique, the practical technology of the WEDM process is based on the typical EDM sparking phenomenon. When the process was first introduced, WEDM has developed from a crude way to make tools and dies to the best way to produce micro-scale parts with the highest level of surface finish quality and dimensional accuracy. This paper reviews the extensive amount of research done from the EDM process to the development of the WEDM. It reports on the WEDM research that involves optimizing the process parameters and examining the impact of various factors on productivity and machining performance. The impact of multiple WEDM process input parameters, including wire speed, peak current, pulse on and off times, and peak on material removal rate (MRR), surface roughness (Ra), and micro structural analysis, on various process output responses is reviewed in this study.","PeriodicalId":517869,"journal":{"name":"1, 2024","volume":"3 26","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140285499","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}

This study focuses on developing a composite coating of polyetheretherketone (PEEK) and silver nanoparticles (AgNP) on 316L stainless steel substrates, aiming to enhance their biocompatibility and antibacterial properties. PEEK is known for its biocompatibility and mechanical properties, while AgNP exhibit excellent antibacterial activity. By combining these materials, we aim to create a coating that not only supports the integration of implants with surrounding tissue but also reduces the risk of infections, a common complication in implant surgery. The fabrication process involves depositing a PEEK layer on the stainless steel substrate, followed by the incorporation of AgNP using a suitable method such as electro spinning or dip coating. The coated substrates will undergo comprehensive characterization, including mechanical testing, surface analysis, and antibacterial efficacy assessment. The mechanical properties of the coating will be critical to ensure its durability and resistance to wear in the demanding environment of the human body. Furthermore, the chemical and biological properties of the coating will be evaluated to ensure its biocompatibility and safety for implantation. This study aims to contribute to the development of advanced coatings for biomedical implants, ultimately improving their performance and longevity.

VASPIF utilizes high-frequency oscillations applied to the forming tool to reduce friction and improve material flow, resulting in enhanced formability and surface finish. Conversely, TPIF\u0000employs two independently controlled forming tools to deform the sheet metal incrementally, allowing for greater geometric complexity and improved accuracy compared to VASPIF. However, TPIF typically requires more complex tooling and setup, potentially increasing manufacturing costs and setup time. Both techniques have shown promise in improving the formability of sheet metal components while offering unique capabilities suited to specific manufacturing requirements. Vibration-assisted single-point incremental forming (VASPIF) and two-point incremental forming (TPIF) are two advanced methods used in sheet metal forming, each with its unique characteristics, advantages, and limitations. In this comprehensive comparison, we will delve into the fundamental principles, process parameters, applications, advantages, and challenges associated with both techniques. Starting with VASPIF, this innovative approach involves applying high-frequency oscillations to the forming tool during the incremental forming process. These vibrations serve to reduce friction between the tool and the work piece, facilitating material flow and enhancing formability.

This study delves into the evolution of impact-induced degradation and establishes upper limits on force or Hertz failure thresholds for three distinct composite categories. Impact investigations reveal that the strength of composite materials significantly increases under dynamic impact conditions compared to static ones, underscoring the material's sensitivity to loading rates. Composite materials play a crucial role in achieving effective ballistic protection for armor platforms, given the varying energy levels of the physical loads they must withstand based on their intended applications. Precise design and manufacturing are necessary to provide adequate protection against impacts of different energies: low-energy impacts from tools during maintenance and operations, intermediate-energy impacts from external elements striking the surface, and high-energy impacts from weapons. Fiber-reinforced composite materials find widespread use across the aviation, marine, and terrestrial industries due to their outstanding specific strength, weight reduction benefits, and ease of manufacturing. They are particularly crucial in aerospace and military applications. Polyester resins offer a cost-effective and easily moldable alternative to epoxy resins in many fiberglass applications. This study aims to explore the low-velocity impact characteristics of E-Glass composites, which are more readily available and cost-effective compared to other reinforced composites. The research focuses on evaluating the impact properties of these materials through testing three different samples.","PeriodicalId":517869,"journal":{"name":"1, 2024","volume":"41 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140285817","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}

Nano-additives, due to their unique properties and characteristics, have demonstrated potential in enhancing the lubricating properties of conventional fluids used in MQL. These additives, typically ranging from nanoparticles to nanofluids, offer improved lubricity, reduced friction, and enhanced heat dissipation, thereby leading to better machining performance, extended tool life, and improved surface quality of machined components. By reducing the amount of lubricant used while maintaining or even enhancing performance, MQL with nano-additives not only addresses environmental concerns associated with excessive fluid usage but also contributes to cost savings and increased productivity in machining operations. However, challenges such as dispersion stability, compatibility with base fluids, and cost-effectiveness need to be carefully addressed to fully realize the potential benefits of incorporating nano-additives into MQL lubricants for machining applications.
