IDR @ IIT Bhubaneswar
IDR @ IIT Bhubaneswar is the digital repository which archives research publications, annual reports and other digital contents of IIT Bhubaneswar. It is set up by using an open source digital repository software "DSpace" (developed by MIT & HP) that supports "Open Archives Initiatives Protocol for Metadata Harvesting" (OAI-PMH) and uses Dublin Core metadata.The repository is hosted and maintained by the Central Library, IIT Bhubaneswar.

Droplet generation inside the microchannel and its manipulation�are one of essential droplet microfluidics processes. Many researchers study the physics behind droplet generation inside the T-junction microchannel; still, a thorough understanding of the concepts behind droplet formation is missing. The current investigation focuses on the parametric study of aqueous droplets in oil for a T-channel. This study examines the impact of numerous parameters, including the continuous phase capillary...
The United Nations aims to preserve, evaluate, and conserve cultural heritage (CH) structures as part of sustainable development. The design life expectancy of many CH structures is slowly approaching its end. It is thus imperative to conduct frequent visual inspections of CH structures following conservation guidelines to ensure their structural integrity. This study implements a custom defect detection, and localization supervised deep learning model based on the you only look once (YOLO) v...
The present research aims to determine the single-phase heat transfer and pressure drop across the heating tube (bluff body) of different configurations using the ANSYS-2020R2 fluent module in the 2D computational domain. The water flows across the tube with a velocity ranging from 0.01 to 0.05�m/s. The heat transfer coefficient (HTC) is found to decrement from horizontal ellipse to semicircle to hexagon to vertical ellipse to inverted triangle to circular, to triangle. The maximum enhancemen...
This paper analyses the effects of a non-uniform laminar flow past a circular cylinder using the direct numerical simulation approach. Compared to the cylinder immersed in a uniform flow case, modifications caused by the non-uniform approaching flow on the evolution of the flow and sound fields are studied in detail in the present work. The prescribed non-uniform velocity profile at the inlet has a Gaussian distribution and imitates a jet or a wake flow velocity profile. The sound is generate...
Increased frequency and intensity of extreme events can make offshore constructions unsafe due to the rapidly shifting wind-wave pattern. The consequences of climate change are disregarded by the current performance-based design of offshore wind turbines (OWT). The Statistical Downscaling Model (SDSM) and Artificial Neural Network (ANN) algorithm are used to present a simplified approach to enable the inclusion of future climatic projections in the design of spar-floating wind turbines. A two...
Kristen Radtke's graphic memoir Imagine Wanting Only This (2017) visually chronicles the author's journeys through post-apocalyptic sites including abandoned cities, derelict landscapes, and architectural ruins in order to process the grief over the loss of her uncle and to confront her recurrent thoughts on mortality. Diagnosed with a fatal heart condition that catapults her into reflections on the transience of human existence, Radtke seeks answers by engaging in a series of dark tours to f...
A numerical study is presented to analyze the effect of internal flow channels on latent heat thermal energy storage (LHTES) systems with encapsulated phase change materials (PCMs) while maintaining constant PCM volume. A 3D cubical domain is modeled with a PCM capsule located at its center subjected to hot heat transfer fluid (HTF). Internal channels are made into the PCM capsules to improve the melting rate. Maintaining a constant volume makes the total latent energy stored constant althoug...
Aluminosilicate minerals serve as the starting point for the chemical process of geopolymerization, which produces binders with minimal environmental impact. Fly ash (FA) was employed as a precursor for developing these binders. However, the use of this novel binder in the construction sector is constrained since oven curing has been employed to quicken the aluminosilicate�s polycondensation. Therefore, the present work determines whether it was possible to produce binders with favorable mech...
The hydrogen bonding structure and dynamics of water are investigated by varying the concentrations up to 6.18 m for full-charged and the electronic continuum correction with rescaling (ECCR) charged model for NaCl solutions using classical molecular dynamics simulations. We have also considered the seven different (MCl/NaX) salt solutions at 6.18 m with varying monovalent cations (M+) or anions (X-). The first and second solvation shells of water in both full- and ECCR models are affected by...
The geopolymer binder is gaining prominence as an eco-friendly alternative to ordinary Portland cement (OPC), aiming to decrease CO2 emissions during the manufacturing of OPC. Geopolymers, which are mineral-based polymers formed from materials rich in silicates and aluminates, undergo a complex process of aluminosilicate gel creation through polymerization when activated by alkaline substances. The proportion of alkaline solutions used plays a pivotal role in the process of geopolymerization....
