Atomization is the process of fragmenting bulk liquid into smaller droplets. 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.

This work presents the various steps involved in performing finite element analysis of computational fluid mechanics system to simulate water impingement on a hot plate for a run-out table experiment. The analysis is conducted for half the plate during the cooling process due to symmetry. The steps include creating a modelling plan, material selection, geometric modelling, model meshing, applying boundary conditions, and obtaining the final temperatures of the steel plate and environment. The software used to conduct the finite element analysis is ANSYS Fluent.

The scope of this study is the investigation of the effect of microstructure on fatigue behavior of Ti-15V-3Al-3Sn-3Cr (Ti 15–3) metastable beta titanium alloy. 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.

UAE's National Space Strategy 2030 is in alliance with the country's policies and national strategy and aims to achieve its vision in the various area of explorations of space, space-technologies and space-innovations. Along with this, UAE has come up with their space policy and is in the process of finalising their space sector law and space regulations. 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. In this back drop it is pertinent to analyse the international obligations that UAE have under the various space treaties, conventions and norms which it has committed to abide by.

The objective of this paper is to review the recent work in which Additive Manufacturing AM (3D printing) techniques are used in the mechanical characterization of several engineering materials, e.g., metallic, ceramic, composite and polymeric. The investigations adopted by several researchers are reviewed to demonstrate the applicability and validity of AM techniques in replicating the used complex specimens' geometry. 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. It can provide both the dimensional accuracy of specimens as well as producing accurate internal flaws or profiles that affect the performance of a material.

In this study tensile test simulations were conducted on fiber reinforced polymer composites of different fabric combinations using ANSYS Workbench 16.0 software platform. Hybrid and Non-hybrid composite laminates were modeled using Kevlar, Carbon and E-glass fabrics as reinforcement and Epoxy LY564/Aradur 2954 formulation was used as the matrix mixture. Tensile tests simulations were conducted on the specimen according to ASTM D3039 standards. The effect of hybridization on the Specific Strength and Specific Modulus of the composite laminates were compared. From the results it was observed that Carbon/Kevlar/Epoxy laminate specimen was ideal for structural applications where high Sp. Strength and high Sp. Modulus is required.

Periodic cellular solids, due to their ability to provide high stiffness and strength to weight ratios, have become common in engineering applications requiring weight minimization. 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.

In this paper, a new modification for particle swarm optimization (PSO) is developed. It has been found previously that making the learning coefficients of PSO variable enhances the performance in terms of convergence rate and obtaining the global minima solution. This has inspired a lot of researchers that investigated the effect of the coefficient's behavior on the PSO performance. However, the works in this field is still limited. This work presents a novel idea of using asymmetric curve of the modified PSO to represent the coefficient behavior. The method is tested and compared to previously reported techniques. The results are promising compared to most common methods in the field.

Time since death TSD or Post-Mortem Interval PMI is the estimated time between death and discovery of the cadaver. 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.

In this paper we focus on the design and testing of a graphene based sensor for applications in oil industry. The sensor is designed to target the specific need of the oil industry related to monitoring and preventing scale formation in oil pipelines. The graphene sensor was setup for resistance measurements using four-probe technique. 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. We have successfully achieved a sensitivity of 68% to 0.02MoI/L of Sr. ions concentration in DI water. The results obtained were consistent for several hours of measurements and even after 2 days the sensitivity is still about 36%.
