The newly proposed MCHS is made up of circular microchannels slotted from the top within a trapezoidal shape, and its cooling effectiveness was compared to that of traditional rectangular MCHS. Each MCHS under consideration has the same hydraulic diameter and heat transfer surface area. Water volumetric flow rates (Qin) with a wide range of values are used, ranging from 40 to 90 ml/min, with the fluid inlet temperature set to 20 oC. A constant heat flux boundary condition of 100 W/cm2 is supplied on the MCHS bottom. The results demonstrated that the inclusion of reentrant trapezoidal shapes can disrupt both hydrodynamic and thermal boundary layers, as well as accelerate fluid flow and mixing in the main flow, resulting in a significant heat transfer enhancement. Furthermore, at Qin=90 ml/min, the average Nusselt number (Nuavg) of compound MCHS increased by 2.16%, while total pressure drop and total thermal resistance decreased by 1.73% and 1.57%, respectively, when compared to the straight rectangular counterpart.","PeriodicalId":394166,"journal":{"name":"International Journal of Advanced Research in Engineering Innovation","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131844484","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}

The severity of erosion by solid particles depends on several factors, including the properties of the particles (e.g., size, shape, hardness, and velocity), the properties of the material being eroded (e.g., hardness, toughness, and ductility), and the environmental conditions (e.g., temperature, humidity, and corrosiveness). This research has two parts. The first part involves the development of a locally manufactured erosion rig, while the second part is theoretical and utilizes a CFD program. The erosion process was carried out with different cumulative weights from impingement solid particles, impact velocities (25.2, 35 and 45 m/s), impingement angles (30°), feed rate (10 g/min), temperature (25 °C) size diameters of solid particles, (350-500) and percentage of reinforcement silicon carbide composites (5, 8 wt.%) of silicon carbide (SiC). Validation and comparison of the results between practical and theoretical analysis. The target materials are unreinforced polyester, polyester -5 wt % SiCp composite and Polyester -8 wt % SiCp composite. The composites with 5 wt.% SiCp shows better erosion resistance than unreinforced polyester and 8 wt.% SiCp composite. And, for 8 wt.% SiCp composite, it could be the loss of ductility associated with more weight percent of SiCp added, which may be attributed partly to increases in erosion rate.","PeriodicalId":394166,"journal":{"name":"International Journal of Advanced Research in Engineering Innovation","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130772802","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}

The result showed that CO2 was measured below the maintenance standards of KHDA regulation at all measurement points, nursery A at 870 ppm and nursery B at 860 ppm. PM10 has exceeded the maintenance standard of 100 μg/m3 in the playroom and nursery room of nursery A due to less cleaning times and ventilation. TVOC was 1,504 μg/m3 and 723 μg/m3 in both facilities, exceeding the recommended standard of 400 μg/m3 in the nursery room. CH2O concentration was below the maintenance standard at all measurement sites.

Frank Gehry is an architect pursuing extreme forms and thinks modern box-shaped architecture is bland and lacks feeling/passion/love. This paper aims to examine the characteristics and meaning of the museums designed by Gehry, Gehry's unique architectural view, and the elements of his museum designs. As a methodology, the classification of modern museums in Newhouse's \"Towards a New Museum “and trends in modern museum architecture are classified into six categories in Montaner's book \"Museums for the 21st Century,\" which are used as a framework for comparative analysis to point out the characteristics of the Gary Museum and derive the location and meaning in modern museum architecture. The result shows that his architectural tendencies of fragmentation and duality are applied to the Gary Museum, revealing complex characteristics in terms of composition by contrasting combinations of formality and irregularity in materials and forms. The intricate design of the Gary Museum reveals its strong presence by creating a sculptural museum that encourages a four-dimensional experience both inside and outside. It was statistically proven that the above characteristics of the Gary Museum represent an aspect of the modern museum that is becoming a popular entertainment medium. A relaxed and comfortable exhibition environment was promoted by weakening the excessive rigidity in the exhibition space through the changeable ceiling treatment. Gary's museums were born between radical experimentalism and a pragmatic professional temperament.","PeriodicalId":394166,"journal":{"name":"International Journal of Advanced Research in Engineering Innovation","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133257044","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}

Peat bogs are an important ecosystem that contributes significantly to global climate stability. Peat from Malaysia is tropical peat. This peat has distinct features that distinguish it from other types of peat. This soil is normally dark reddish-brown to black and made up of partially decomposed leaves, branches, twigs, and tree trunks with a low mineral content in its natural state. Various of experimental and study has been conducted to improve and stabilize of peat soil due to compressibility and geotechnical characteristics of peat. Peat also is an inadequate soil for sustaining foundations in its natural condition due to its high moisture content (>100%), high compressibility (0.9-1.5), and poor shear strength (5-20 kPa). Thus, injection method of Eco-Processed Pozzolan (EPP) will be used to increase the stabilization of peat soil. The study of index properties such as von Post scale, natural moisture content, liquid limit, bulk unit weight, specific gravity, initial void ratio, pH value, linear shrinkage, plastic limit, fiber content, ash content and organic content and composition compressibility of peat soil will be conducted; present of compressibility of peat soil with Eco-Processed Pozzolan (EPP). A comprehensive laboratory work will be carried out to study the compressive parameters of hemic peat stabilized with various quantities of Eco-Processed Pozzolan (EPP) which they were subjected to Rowe Cell Consolidation test between disturbed and undisturbed samples. From this research, the relationship between peat soil and Eco-Processed Pozzolan (EPP) will be determined whether usage of EPP may can increase a stabilization of peat soil and be a ‘binder’ element in peat soil.","PeriodicalId":394166,"journal":{"name":"International Journal of Advanced Research in Engineering Innovation","volume":"222 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132681865","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}
