Dr. Shibani Khanra Jha, Birla Institute of Technology & Science, Pilani
In this session, Dr. Shibani Khanra Jha, associate professor at BITS Pilani, will discuss the dynamic response of delineated geothermal reservoirs exploited under doublet, triplet, quadruplet, and quintuplet extraction schemes. She will discuss how the reservoir response is simulated with a 3D-coupled fluid flow and heat transport model. Different variants within the proposed extraction schemes have been synthesized by varying the well spacing and discharge rates.
Dr. Jha will highlight how the dynamic response of the reservoir under various extraction schemes is observed to identify the most favorable extraction scheme in terms of power generation and the economics involved in the installation. The simulation results also help identify the feasible well spacing based on the structural formation and the extent of the geothermal field and distribution of rock types.
3D simulations are performed to estimate the extraction temperature and extractable power under an identified extraction scheme with different operating conditions, which are synthesized by varying well spacing, injection/extraction rate, injection temperature, and injection depth. Dr. Jha will also cover the power potential of geothermal reservoirs under various operating conditions of the extraction scheme to predict crucial parameters such as the thermal breakthrough period and recovery factor.
In this session, we will cover the updates in the electromagnetics products.
In version 6.2 of the AC/DC Module, nonlinear motor and transformer simulations have become significantly faster due to a new method for time-dimension periodicity. The module now includes dielectric models for tissue simulation, and dedicated functionality streamlines the modeling of imperfectly stranded conductors, like litz wires. For RF Module and Wave Optics Module users, high-frequency analysis, based on the boundary element method, is enhanced by the introduction of new boundary conditions. The Plasma Module offers more efficient handling of chemical reactions in plasmas and microwave plasma simulations. The Semiconductor Module includes several performance and robustness improvements, enabling users to preview doping profiles before solving.
Nilesh Gaware, Oceaneering International Services Ltd.
The Freedom™ ROV, developed by Oceaneering International Services Ltd., represents a cutting-edge solution in underwater robotics. This remotely operated vehicle (ROV) is designed for versatile and high-performance operations in subsea environments. It excels in deep-water exploration, inspection, and intervention tasks, offering advanced capabilities such as high-definition imaging, precise maneuverability, and robust durability. The Oceaneering team is dedicated to advancing the development of ROVs by focusing on high-performance battery assemblies. Oceaneering's fleet of electric-powered ROVs relies on these batteries, which they are optimizing to overcome the challenges of space limitation, pressurized environment, range enhancement, and minimal charging time. By utilizing computational fluid dynamics (CFD), they enhance the cooling methodology and virtually test the batteries against extreme environmental conditions. Maintaining the battery cells within an optimal temperature range is crucial for operational efficiency and safety. Although Oceaneering does not manufacture the individual cells, they assemble them into packs that must deliver the required voltage while ensuring minimal temperature differential across cells. This is vital because any imbalance can impact the entire pack’s performance, given that all the cells are connected.
This session will cover news in the Chemical Reaction Engineering, Electrochemistry, Electrodeposition, Corrosion, Battery Design, and Fuel Cell & Electrolyzer modules.
Highlights include:
- New and improved features for porous reactor modeling in the Chemical Species Transport interfaces
- Modeling species adsorption and desorption on electrode surfaces
- The new Cathodic Protection interface for modeling corrosion protection
- New intercalation strain functionality for battery electrode modeling
- Electroosmotic water drag and membrane crossover in fuel cells and electrolyzers
Dr. Pradyumna Ghosh, IIT BHU
Clinical trials have established high-temperature treatment of cancer, i.e., raising the tissue temperature above 55 degrees Celsius, as an effective and reliable noninvasive method in the treatment of cancer. Moreover, with the developments in computational techniques and computing capacity, personalized treatment planning (TP) has matured and become a potent tool for optimizing treatment quality. In this session, Dr. Pradyumna Ghosh, a professor at IIT BHU, will discuss a framework developed to make such treatment planning more accurate and efficient using simulation tools.
Currently, tomographic images (CT or MRI scans) of cancer-affected patients are processed to produce the actual 3D model of the cancer tumor through radiofrequency (RF) or microwave (MW) ablation. In this patient-specific modeling, the entire temperature history of and degree of tissue injury are logged for the entire ablation process using the Pennes’ bioheat transfer model. Eventually, this helps the clinical practitioner to develop a case-specific treatment plan. In the case of RF ablation, the clinical practitioner uses an empirical chart to decide on the ablation voltage and frequency. However, the new framework suggested by Dr. Ghosh enables clinical practitioners to compute patient-specific parameters with the help of a detailed parametric study. At present there is no existing tool providing patient-specific treatment planning that is affordable and accurate enough to be deployed in common clinics. The development of such a computational tool will play a major role in the upcoming years to establish personalized treatment planning as an effective, cheaper, and safer addition to the thermal treatment of cancer.
In this session, we will cover the updates for structural mechanics and acoustics in version 6.2.
Users of the structural mechanics products will see updated damage and fracture modeling capabilities, along with tools for circuit board warpage computation and magnetic–structure multiphysics analysis of electric motors. This version also introduces capabilities for studying transport in solids, which can be used for modeling electromigration and other phenomena. Moisture transport is now more tightly integrated with structural deformations, including how it modifies the storage coefficients and porosity. Inertia relief analysis — now automated in the new version — makes it easier to analyze unconstrained structures that are accelerated by external loads.
This version also introduces a viscoplastic material model specialized for the unique properties of lithium in battery applications. Usability and performance have been significantly enhanced for parameter estimation of experimental data, including uniaxial, biaxial, and cyclic load cases.
For Acoustics Module users, frequency-dependent impedance boundary conditions now enable audio engineers to more accurately simulate acoustics in the time domain with realistic absorption. The Poroelastic Waves feature has been extended to include anisotropic materials, and users will notice considerable performance enhancements in impulse response calculations for room and cabin acoustics simulations using ray acoustics.
COMSOL Multiphysics® version 6.2 comes packed with new functionality for fluid flow and heat transfer.
In the CFD Module, large eddy simulation (LES) is implemented for compressible flow for accurate modeling of the flow of gases at Mach numbers below 0.3. There are also seven new Reynolds-averaged Navier–Stokes (RANS) turbulence model interfaces for high-Mach-number flow. A new potential flow interface can be used to get good initial values for the flow and to obtain faster convergence.
In the Heat Transfer Module, the SST turbulence model has been added for accurate nonisothermal flow and conjugate heat transfer simulations. The ASHRAE weather data feature is extended with a search function based on a GPS position, i.e., the feature finds the closest weather station to the GPS position. Additionally, a new thermal connection feature has been added in order to connect and add thermal resistance between two surfaces that are not geometrically in contact in the model.
Join us in this session to learn more about these updates as well as additional fluid flow and heat transfer news!
