Proposta de uma ferramenta de cálculo para dimensionamento hidráulico de descarregador em labirinto

Abstract

This work addresses the development of a calculation tool for the hydraulic design of labyrinth weirs, aiming to provide a comprehensive and in-depth understanding of the process. An introductory approach highlights the importance of these structures in water flow management and underscores the inherent complexity of their design. The employed methodology applied in nature with exploratory objectives, aiming to develop an innovative tool. The research followed a qualitative approach based on bibliographic research, with detailed collection and analysis of discharge curves and the study of key hydraulic parameters. The primary objective of the thesis is to develop a calculation tool for the hydraulic design of labyrinth weirs. During the development, the dissertation explored knowledge about the operation of labyrinth weirs and addressed the studies and recommendations of the main researchers on the subject. Subsequently, the process of modelling the calculation tool and creating its user guide was presented. The calculation tool has the capacity to generate designs with proper efficiency control and cost viability, applying diverse knowledge to ensure robustness and reliability in the tool. The dissertation concluded that the mathematical model applied in the calculation tool proved to be effective, aligning with the theory and parameters found in the literature. The analysis of the discharge curves highlighted the abacus of Magalhães & Melo as the most robust and practical. The CV parameter proved to be crucial for economic viability, showing a significant reduction in costs. However, the use of empirical equations resulted in conservative solutions and possible over-dimensioning. Nonetheless, it was capable of generating results and trends that fully align with the theory, highlighting the model’s versatile potential. Its contribution represents a significant advance in hydraulic engineering, offering valuable insights and promoting the evolution of projects in this field.
