This review systematically examines the role of mechanical vibrations in enhancing heat transfer across various thermal systems. Although vibrations are traditionally considered detrimental to mechanical integrity, controlled application of vibrational forces can significantly improve thermal performance by promoting fluid mixing and surface turbulence. The study synthesizes findings from theoretical, numerical, and experimental research involving different geometries such as flat plates, cylinders, and microchannel structures.
Results consistently demonstrate that specific ranges of vibration frequency and amplitude can enhance convective heat transfer, with some studies reporting improvements up to 250%. Conversely, inappropriate vibrational conditions can lead to performance degradation or mechanical failure. Key parameters influencing outcomes include vibration mode, fluid properties, system configuration, and thermal boundary conditions. Applications span aerospace, electronics cooling, and energy systems, where vibrational techniques have reduced fouling, improved heat exchanger efficiency, and enabled lightweight thermal management solutions.
