    South Asian Integration Prospects and Lessons from East Asia

    No full text
    In the context of the low levels of regional cooperation among South Asian countries when compared with the successful results from cooperation in East Asia (consisting of South East and East Asian countries), the objective of this paper is first to assess the prospects of cooperation among South Asian economies and then to draw lessons from East Asian regional experiments for South Asian regionalism for the betterment of these prospects. The main argument of the paper is that South Asia should adopt a twin-track approach: better integration within itself and better integration with rest of the world particularly East Asia. Both tracks would complement and supplement each other ensuring a greater chance of success.South Asian integration prospects, Lessons from East Asian regionalism, Open regionalism, Asian development

    Indirect estimation of mean vorticity from polarized emission of nanoparticles in turbulent duct flows

    Optical measurement techniques are widely used in fluid mechanics to measure quantities like velocity, vorticity, and temperature. They are usually non-intrusive visualization techniques that provide a major advantage by not influencing the flow properties. Most of the developed measurement techniques estimate vorticity by computing the gradients of the measured velocity fields. In this project, the idea is to directly measure the mean vorticity using polarized emission of nanoparticles. The nanoparticles are excited using vertically and horizontally polarized laser. Accordingly, the emission from these nanoparticles is separated into vertical and horizontal polarized emissions respectively. Depending on the percentage of fluorophores in the nanoparticles whose absorption dipole moment is parallel to the excitation electric vector of the laser, the polarized emission is varied. The nanoparticles in the quiescent fluid state have a characteristic polarization (or anisotropy) depending on the chemical composition of the nanoparticle. However, in turbulent flows, depolarization of the particles can occur because of the rotation of the nanoparticles due to vorticity. Based on this idea, the vorticity can be estimated by quantifying the depolarization in turbulent flows. To verify the above phenomena experimentally, steady-state polarization measurements were conducted. An experimental setup was built specifically to measure depolarization from these nanoparticles. Important preliminary tests like lifetime measurements, spectroscopic studies, and photo-bleaching experiments were conducted. Based on these results, hybrid europium based chelated spherical particles were chosen. To further understand the properties of these particles in a quiescent flow, a consolidated set of anisotropy measurements were conducted to study their oxygen sensitivity in the surrounding medium, viscosity dependence and the effect of its concentration in the fluids. Analytical correlations which was developed in-house to translate the depolarization of the nanoparticles to vorticity was used in this thesis. Flow in a square duct was studied to estimate the vorticity along the edges and further compare it with the DNS data. Two additional non-dimensional numbers ND1 and ND2 were introduced to interpret the underlying physics behind the problem. The variation of synthetic signals was studied for different Re, fundamental anisotropy r0 and the non-dimensional number ND2. These synthetic signals showed a drop in anisotropy near the edges of the square duct that has occurred probably due to vorticity. Emission polarized intensity signals and the anisotropy contours for Re = 0 and Re = 4434 were analyzed. Due to the measurement error, the contours were column averaged and respectively compared their variation along the width of the square duct. A drop in anisotropy was observed for Re = 4434. Using the ratio of emission intensities for each excitation polarization, the vorticity was estimated using the optimization algorithm. The estimated vorticity Ѡy shows similar trends compared to DNS data which is a promising evidence for the proof of concept. However, the results are not overlapping from the repeatability studies due to the high sensitivity of the optimization algorithm and the random error from the measurement equipment. To improve this technique in the future, transient experiments have to be conducted to estimate vorticity accurately and to capture the underlying physics.Mechanical Engineerin

    Geomechanical Study of Underground Hydrogen Storage

    With the rise of renewable energy and the drive to achieve net-zero emissions, energy storage has become a crucial component of the energy sector to address the challenges of intermittency. The vast subsurface environment offers significant storage potential, capable of accommodating terawatt-hour (TWh) capacities. One approach to leverage this storage capacity involves converting renewable energy into hydrogen and storing it underground within salt caverns and depleted porous reservoirs. This stored hydrogen can then be utilized as needed. However, this cyclic injection and production of hydrogen will exert repeated stress on the subsurface, resulting in periodic changes in pressure.One critical aspect that requires investigation for the safe storage of hydrogen (H2) is the field of geomechanics, which becomes essential in both salt caverns and depleted reservoirs. To gain a better understanding of this, a comprehensive review of the geomechanics involved in underground hydrogen storage was conducted to examine existing knowledge and identify research gaps. To delve deeper into the influence of geomechanics, particularly regarding the inelastic creep deformation of rocks in salt caverns and depleted porous reservoirs, numerical simulations were employed. Given the potential costliness of fine-scale simulations, multiscale simulations were carried out using algebraic multiscale methods. Constitutive models were utilized to analyze deformation patterns in and around the reservoir, assessing their impact on subsidence or uplift.In order to further comprehend the effects of cyclic loading on rocks, constitutive models were developed based on extensive experimental data obtained from sandstone rocks subjected to long-term stress conditions. These models aided in uncovering the underlying physics of rock behavior when exposed to different stress regimes during prolonged cyclic loading. Subsequently, these models were integrated into finite element method (FEM) simulations to observe their impact on field-scale scenarios, with a synthetic Bergermeer case study serving as an example.To enhance the computational efficiency of multiscale methods, unsupervised machine learning techniques were applied to optimize the formation of computational grids, utilizing graph theory techniques such as Louvain and random walk algorithms. These optimized grids were then compared with the grids generated from METIS to evaluate the computational performance of pressure solvers in a commercial scale simulator.Reservoir Engineerin
