It defines the motivation, problem statement, procedure, and scope, then reviews fundamental boiling heat-transfer concepts including pool and flow boiling as well as comparisons. The work builds a database from literature, applies selection criteria, performs data reduction and property calculations, computes dimensionless numbers, and surveys flow-boiling heat-transfer correlation literature to identify limitations and challenges.","University of North Dakota  \nUND Scholarly Commons  \n\n| Theses and Dissertations | Theses, Dissertations, and Senior Projects |\n| --- | --- |\n| January 2025\u003Cbr>Predictive Modeling For Multiphase Flow Boiling Heat Transfer By Integrating Computational Fluid Dynamics And Machine Learning Approaches\u003Cbr>Mohamed Elfaham\u003Cbr>How does access to this work benefit you?
