Gas Centered Swirl Co-axial (GCSC) injectors belong to the class of air assisted injectors wherein atomization proceeds by the relative motion between an swirling annular liquid sheet and a fast moving central on its inside. These class of injectors are relevant in rocket propulsion applications due to the high gas to fuel momentum ratios. Experimental and analytical research have been done with GCSC injectors over the past few decades. The current study is an attempt to review the important works done till date on GCSC injectors with primary focus on the atomization performance of the class of injectors over a range of operating conditions.","PeriodicalId":237887,"journal":{"name":"2020 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124278310","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}

Aging treatment was applied to Ti 15–3 alloy at low and high aging temperatures. The fatigue crack initiation and propagation behavior of the alloy was determined by applying fatigue crack propagation tests under constant amplitude loading. Fatigue crack propagation in the solution treated sample showed a propagation due to grain boundaries, while the aging treated samples were affected by the homogeneous distribution and size of the $a$ phases. The fatigue crack propagation rate decreased with increasing aging time due to the formation of $a$ phases at low temperatures for long periods. At high aging temperatures, the increase in the aging time caused the $a$ phases to grow and the $a$ platelets amount to decrease. This situation created an inhomogeneous distribution of $a$ phases in the microstructure and adversely affected the fatigue behavior of the sample. The highest rate of fatigue crack propagation was observed in 450°C 10 hour sample, while the lowest rate of fatigue crack propagation was obtained in 300°C 10 hours sample.","PeriodicalId":237887,"journal":{"name":"2020 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121094779","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}

UAE is also a State party to three of the main international space law treaties. The country is seeking to establish itself as a major player globally and create a hub for space science and technology. To achieve this, the country has already began investing in capability building and also creating a conducive environment- scientific, legal and financial, which can attract future space projects and encouraging large scale investment both in public and private sectors.

The research concluded that additive manufacturing opens doors to solving many research questions and challenges and significantly improves the cost-effectiveness and time factor of the current standard and nonstandard tests.

Such applications relate to aerospace, marine, renewable energy, and automotive industries. The continuously increasing industrial relevance of periodic cellular solids has motivated developing methodologies to improve their elastic and failure properties. Introducing hierarchical features in periodic cellular solids proved as one of the most effective methods to improve their in-plane elastic and strength properties. This approach was applied to aluminum honeycombs and resulted in more than doubling their in-plane stiffness. However, the effect of introducing hierarchical features on the out-of-plane properties of periodic cellular solids in general and honeycombs in particular has not been fully investigated yet. Accordingly, this work investigates the effect of introducing hierarchical features on the out-of-plane behavior of honeycombs. In particular, this work investigates, using finite element computations, the effect of introducing hierarchy on the buckling strength of hexagonal honeycombs. Results show that hierarchy when carefully introduced, can enhance the buckling strength of honeycombs by more than 170% without increasing their weight.","PeriodicalId":237887,"journal":{"name":"2020 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116057577","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}

Estimation of PMI is very challenging in medico-legal investigations for over years. Numerous methods have been proposed to estimate PMI. The aim of the present review was to explore the early changes of body after death named postmortem changes and the body decomposition after death. Emerging technologies for PMI estimation including the measurement of body temperature, the electrical and mechanical stimulation, the entomology and the post-mortem biochemical changes in body fluids were also discussed. We focused on the biochemical changes related to enzymes and proteins happening after death in the biological fluids and body tissues. Altogether, this review provides better understanding on the emerging technologies in PMI estimation which could be helpful for law enforcement and authorities in the community.","PeriodicalId":237887,"journal":{"name":"2020 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122487330","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}

It was tested on deionized (DI) water as a standard reference and crude oil as a harch, mixed, and inhomogenious environment. After the calibration tests, the graphene sensor was used to monitor the concentration of strontium ions in DI water as one of the key elements responssible for scale formation in oil pipelines.
