Numerical Modeling of Effective Thermal Conductivity for Polymineralic Rocks using Lattice Element Method
Nima Haghighat, Amir S. Sattari, Hem B. Motra +1
Accurate prediction of rock thermal conductivity under in-situ conditions is essential for characterizing subsurface heat flow. This study presents a numerical framework based on t…
Mineral Type Impact on Thermal Conductivity of Biocement and Biocemented Sand
Shadi Zeinali, Zarghaam Heidar Rizvi, Frank Wuttke
This study experimentally investigates the influence of CaCO3 polymorphs on the thermal conductivity (TC) of biocement and biocemented sand. Calcite-rich biocements consistently sh…
Thermal Acoustical and Mechanical Characterization of Rock under in-situ conditions
Nima Haghighat, Hem B. Motra, Amir S. Sattari +1
Data on the coupled influence of pressure and temperature on rock thermal conductivity remain limited. This study adapts a multi-anvil cubic press to enable steady-state thermal co…
Physics-Informed Neural Networks for High-Frequency and Multi-Scale Problems using Transfer Learning
Abdul Hannan Mustajab, Hao Lyu, Zarghaam Rizvi +1
Physics-informed neural network (PINN) is a data-driven solver for partial and ordinary differential equations(ODEs/PDEs). It provides a unified framework to address both forward a…
