OpenFOAM® Solver Development for

"This book explores bubble dynamics, free liquid surface deformation, heat transfer, and thermal destratification in liquid storage tanks using the open-source CFD software OpenFOAM. It bridges fundamental theory with advanced numerical modeling, serving as a reference for researchers, students, and professionals in multiphase flow.
A key contribution is the development of a new solver, inter Thermal DestratificationFoam, built by modifying interFoam to simulate coupled multiphase flow and thermal destratification. The text details the entire development process, including energy equation implementation, thermophysical properties, finite-volume discretization, and heat
transfer integration within the Volume of Fluid (VOF) framework.
The featured investigations examine how surface tension, liquid viscosity, and liquid density affect bubble behavior and surface deformation across single- and double-gas inlet setups. Additionally, the study introduces two new dimensionless parameters-the Coefficient of Deformation (de) and the Thermal Stratification Decay Coefficient (TSD) to quantify these effects.
Ultimately, the book combines theoretical foundations, solver development, validation studies, and advanced CFD applications, making it a valuable resource for engineers in cryogenic engineering, thermal energy storage, and process engineering.
