Studies on Fluid-Structure Interactions in Hypersonic Flow
Fluid-structure interaction (FSI) represents a critical area of research in aerospace engineering, particularly in the hypersonic flows where aerodynamic and thermal loads significantly impact structural integrity and ...
Passive control and intermittent dynamics of the precessing vortex core oscillation in swirl flows
Swirl is used in modern gas turbine combustor nozzles to achieve reliable flame stabilization and efficient fuel-air mixing. The swirl component in the nozzle jet flow induces an axial vortex. At high swirl intensities, ...
Impact of Groundwater Level Fluctuations on In-Situ Soil Properties using Automated Wave Detection Methods
Understanding the impact of groundwater level fluctuations on soil properties is crucial in geotechnical engineering, as it influences soil strength, stiffness, and stability. Dynamic soil properties such as Poisson's ...
Sub-mesoscale modeling framework for woven fabrics using VAM-based geometrically-exact beam model
In this work, a novel sub-mesoscale model of woven fabrics is developed using nonlinear finite
element methods. The main aim of the work is to develop a framework for modeling woven
fabrics. The yarns are modeled as beam ...
Ultrasonic Guided Wave-based Inspection of Additively Manufactured Components
Layered structural components, such as laminated composites and those made via Additive Manufacturing (AM), are widely used in aerospace and automotive industries due to their various advantages. The layer-wise approach ...
Application of Finite Element Limit Analysis and Other Means to Deal with Problems Involving Foundations and Excavations
The finite elements limit analysis (FELA) is an important tool to solve any stability problem in geomechanics. This method provides lower and upper bounds on the true solution for a material following an associated flow ...
Assimilation of near-surface soil temperature and soil moisture in an unsaturated flow model: State and parameter estimation using synthetic and field experiments
Soil moisture is a key variable governing land surface hydrology, agricultural productivity, and climate dynamics, influencing crucial processes such as evapotranspiration, infiltration, and surface runoff. Accurate ...
Thermal and Thermo-Mechanical Behaviour of Additively Manufactured Hastelloy X
Additive manufacturing (AM) is one of the emerging technologies to manufacture near-net-shape engineering components layer-by-layer using a suitable heat source. The rapid adoption of AM in the field of aerospace owes to ...
Adjoint-Based Aerodynamic Shape and Mesh Optimization with High-order Discontinuous Galerkin Methods
The aerodynamic shape of an aircraft plays a pivotal role in determining its overall performance. Aerodynamic Shape Optimization (ASO) involves systematically modifying the geometry to optimize the aerodynamic objective ...
Control of Alternating Flow Phenomena in Transonic Shock Wave Boundary Layer Interactions Over Payload Region of a Generic Launch Vehicle Model
During the transonic phase of a launch vehicle’s ascent, aerodynamic loads peak due to high freestream dynamic pressure and angle of attack. In addition to steady loads, significant pressure fluctuations arise from Shock ...
