FLUID FORCES ON INCLINED PLANES DURING DAM BREAK SCENARIOS: TOWARDS A GENERAL FORMULA

Abstract

This research paper aims to address the calculation of total force on an inclined plane in the context of dam break induced flow impingement with structures, which are typically complex and require either experimental or numerical simulation techniques for accurate results. Analytical solutions are often not feasible for a wide range of such problems due to their inherent complexity. The primary objective of this study is to develop a general formula for calculating the total force on a plane in the path of a dam break, considering all relevant parameters that can affect the force result. To achieve this objective, the study employs data-driven analysis and dimensional analysis to generate new formulas. The Finite-Volume Method (FVM) with the volume of fluid (VOF) scheme, along with turbulence models, is utilized to simulate the problem using STAR-CCM+ software. The results demonstrate that by utilizing appropriate nondimensional relations for force and time, all force-time curves converge towards a unique curve with acceptable accuracy. The nondimensionalization approach can assist researchers to move toward practical formulas for a wide range of fluid-structure interaction (FSI) problems, and the results obtained are reliable and accurate.
