Numerous industries, including microfluidics, biomedical engineering, and chemical processing, depend heavily on microscale fluid flow phenomena. Designing and improving microscale devices and processes requires a thorough understanding of and ability to predict these phenomena. The main objective of this study is to numerically simulate and experimentally verify microscale fluid flow processes.In this proposed approach method give a thorough analysis of microscale fluid flow in this work that combines numerical simulations and experimental methods. To simulate and forecast fluid behaviour at the microscale, we use computational fluid dynamics (CFD) models. The simulations take into account variables like viscosity, inertia, and intermolecular forces and are based on fundamental principles of fluid mechanics.Utilising cutting-edge microfluidic technology, experimental measurements are carried out to confirm the precision and dependability of the simulation results. In these studies, tiny fluid quantities are controlled, while flow patterns and velocities are tracked. The resulting experimental data are then contrasted with the outcomes of the numerical simulation in order to evaluate the simulation models' capacity for prediction. This paper show how the numerical simulation method may accurately forecast microscale fluid flow events. High levels of agreement between the simulation and experimental results validate the correctness and dependability of the computational models. This paper offers a thorough framework for numerical modelling and experimental validation, advancing the field of microscale fluid flow research.The study found that while the wetting performance had a substantial impact on the size distribution of liquid metal droplets, the droplet diameter showed less dependence on the contact angle. Monodisperse droplets developed as a result of a more hydrophilic behaviour. The numerical model and simulation outcomes show the possibility for precise droplet formation prediction in glass capillary microfluidic devices, especially for high surface tension liquids.
