Epoxy Modified Bio-based Hyper branched Polyurethane/Clay Nanocomposites: Rheology and Biodegradability
Abstract: The rheological study of nanocomposite has significant contribution not only in processing but also reveals the dispersion state of the nano reinforcing agent in the matrix. This study divulges the rheological behavior of epoxy cured Mesua ferrea L. seed oil modified hyper branched polyurethane/clay nanocomposites. The influence of different preparative techniques viz. in situ and ex situ on the rheological properties was also investigated. The nanocomposites prepared by in situ …

Experimental Study on the Impact of Polymer (PAM) in Enhancing Oil Recovery in Upper Assam Basin Oil fields
Abstract: The Upper Assam Basin, one of India’s most mature and extensively exploited hydrocarbon provinces, is experiencing declining oil production due to reservoir depletion and unfavorable crude oil–brine–rock (COBR) interactions. In this context, alkali–polymer (AP) flooding has emerged as a promising chemical enhanced oil recovery (EOR) strategy. AP flooding reduces interfacial tension (IFT) through in-situ surfactant generation by alkali and improves sweep efficiency via polymer-based mobility control, typically using polyacrylamide (PAM). …

Characterization and Stability Analysis of Crude Oil-in-Water Emulsions
Abstract: AbstractProduced water in the form of oil-in-water emulsion is the largest waste stream generated during the oil and gas production. Characterizations of oil-in-water emulsion in terms of stability study with respect to oil droplet size distribution, oil content, total dissolved solids, salinity with respect to time and rheological property have been investigated in the present work. Particle size distributions of freshly prepared oil-in-water emulsion of different crude oil concentration and …

Non-Newtonian Power-law Fluid Flows for Shear Thinning Viscosity in a T junction Channel
Abstract: In this paper, non-Newtonian fluid flow behaviors are analyzed in a two-dimensional T junction channel using Lattice-Boltzmann Method (LBM). The LBM has been built up on the D2Q9 model, and the single-relaxation-time (SRT) method called the Lattice-BGK (Bhatnagar-Gross-Krook) model. The flow patterns are analogous to blood flows in branched arteries for T junction flows. Firstly, the code validation has been occurred for the Newto-nian fluid flows by comparing the accessible …

Computation of Different Stresses Acting on Cantilever Beam Using Hyperbolic Shear Deformation Theory
Abstract: The shear deformation effects are more significant in the thick beams. The classical beam theory (ETB) is based on Bernoulli-Euler hypothesis and the classical plate theory (CPT) is based on Kirchhoff’s hypothesis. The shear deformation effects are more pronounced in the thick beams when subjected to transverse loads than in the thin beams under same loading condition. These effects are neglected in elementary theory of beam (ETB). In order to …

Effect of Sinusoidal and Inverse sinusoidal Load on the Vibration and Buckling Behaviour of Laminated Composite Symmetrical and Unsymmetrical Trapezoidal Panels
Abstract: Using finite element (FE) techniques, this work analyzes the influence of sinusoidal and invers sinusoidal stresses on the buckling behavior of trapezoidal laminated composite panels (also known as trapezoidal laminated composite panels). The discretization of the composite panel is accomplished by the use of an eight-noded iso-parametric plate element, which has five degrees of freedom for each node. Due to the incorporation of Higher Order Shear Deformation Theory (HOSDT) into …

The Study of Structural Behavior of Steel Fiber Reinforced Concrete Beam
Abstract: The steel fibers are most widely used fibers in the present state of development of fiber reinforced concrete (FRC). This is due to the advantage that the addition of fibers to concrete converts the brittle characteristics of concrete to a ductile one, such as slabs and thin webs, where the use of shear reinforcement is not possible, the steel fibers gives them the strength to resist shear. The present study …

Light Weight Applications of Sandwich Panels in Various Industries
Abstract: Sandwich construction is of particular interest and widely used, because the concept is very suitable and amenable to the development of lightweight structures with high in-plane and flexural stiffness. Sandwich panels consist typically of two thin face sheets (or facings, or skins) and a lightweight thicker core. Commonly used materials for facings are composite laminates and metals, while cores are made of metallic and nonmetallic honeycombs, cellular foams, balsa wood …

Cubic B-splines for Isogeometric Analysis of Laminated Composite Plates Subjected to Hygroscopic Loading Using Classical Laminated Plate Theory
Abstract: Composite laminates are inevitably used in several engineering structures due to their high strength and stiffness to weight ratio. The laminates are subjected to change in moisture content and the flexural behavior leads to change in the strength. Presence of moisutre may induce residual stresses and strains. Isogeometric analysis is a well-proven method to perform analysis of laminated composite plates. The main focus of this study is to apply isogeometric …
