The hydrodynamic demeanor of falling particles and the liquid media in which they fall, supported by data analytics, is indispensable in the computation of the terminal falling rate. which is a critical concept in many civil engineering disciplines. The application of terminal settling velocity becomes vital to prevent the settling of microplastic particles (< 5 mm in size), several metal particles, polymers, etc.; especially those of irregular shape. Past research has explicated and inveterate that the downward terminal motion of a particle is a function of the rheological characteristics such as specific mass, density, shape, size, sphericity, projected area, etc. of the dropping particle, as well as the mass, kinetic viscosity, temperature, etc. of the fluid through which it falls. The actual circumstances of falling particles and the fluid through which they descend during the settling process deviate significantly from the conditions anticipated in Stoke’s revolutionary work in the computation of fall velocity; hence, the falling rate is highly impacted. The current research intends to integrate the work of several researchers on the influence of particle and liquid rheologic properties in the computation of fall velocity. The present research focuses on expanding the available literature, and applying current information to forecast the falling rate of irregular shaped particles, particularly a mixture of metals, polymers, microplastics, composites, and natural gravels, by suggesting data-driven method of particle characterization.

Keywords: Viscosity, Characterization, Shape factor, Settling velocity, Drag, Buoyant force Reynolds Number, Flow Regime.
