This research develops a unified methodology combining machine learning, numerical simulations, and experimental investigations with manufacturing philosophies to set a new holistic benchmark. Bioinspired hybrid pin-fin geometries inspired by nature structures achieve 30–70% higher heat transfer potential, lower thermal resistance, and improved flow manipulation, while addressing manufacturability and thermal efficiency.","Enhancing Heat Transfer and Thermal Management Efficiency in Micro Heat Sinks through Machine Learning Algorithms  \nMohammad Abdullah Hossain Harris  \nSustainable Engineering and Energy Technologies School of Physics, Engineering and Computer Science  \nSupervisory Team:  \nProfessor Hongwei Wu (University of Hertfordshire)  \nDr. Anastasia Angelopoulou (University of Westminster) Dr. Wenbin Zhang (Nottingham Trent University)  \nExamination Team:  \nProfessor Yuying Yan (University of Nottingham)  \nDr. Guogang Ren (University of Hertfordshire)  \nSubmitted to the University of Hertfordshire in partial fulfilment of the requirement of the degree of Doctor of Philosophy  \nOctober 2024  \nDeclaration of Originality  \nI declare that the work in this dissertation was carried out under the requirements of the University’s Regulations and Code of Practice for Research Degree Programmes and has not been submitted for anyother academic award.
