Simulação de sensor de fluxo ultrassônico

Abstract

This study presents the development and evaluation of an ultrasonic sensor model for water flow measurement, using computational simulations in the Julia programming language. The simulation employs the Navier-Stokes equations to describe the laminar flow of fluid in a pipe and aims to simulate ultrasonic sensor techniques in flow measurement systems. The simulations provided an analysis of the sensor’s behavior under different operating conditions, varying parameters such as fluid viscosity and pressure gradient. The study applied evaluation metrics, including precision, sensitivity, and linearity, to assess the model’s performance in various scenarios. Additionally, the influence of noise was evaluated, focusing on understanding how the model behaves in realistic conditions. The results indicate that the developed model demonstrated considerable accuracy in low-velocity fluids, along with a linear response. The work also highlights the potential of computational simulations for improving flow sensors and advancing technologies applicable to water resource management and instrumentation.
