In this tutorial model, learn how to simulate a generic wetted transient-time ultrasound flowmeter with COMSOL Multiphysics® simulation software. The model setup solves the transient problem of a signal traversing the flow downstream. First, we use the CFD Module to calculate the steady-state background flow in the flowmeter. the ultrasonic mechanical characterization of anisotropic materials (Figure 2). The main features of this device are a goniometer tool and an advanced data acquisition system. The goniometer allows to rotate the sample during the test, enabling to measure the time-of-flight of ultrasonic waves through the sample for different angles of propagation.. The coil length and coil area are used to compute lumped variables, such as the induced voltage or the total resistance. For models representing only a part of the geometry (due to symmetry), the total length and cross-section area of the coil (referred to as coil length and coil area) are computed by multiplying the domain or boundary length. In many cases, piezoelectric transducers are used to send and receive the ultrasonic wave. This tutorial shows how to simulate an ultrasonic flowmeter with piezoelectric transducers in the simplified no-flow case. The model is based on the discontinuous Galerkin (dG) method which is well suited for acoustically large transient problems. technique and capacitive micromachined ultrasonic transducer (cMUT) is a good choice to perform these measurements. The main advantage of cMUT is ideal design compatibility with the ngerprint sensor based on capacitive method - a product of Fingerprint Cards AB (FPC) which participates as an industrial partner in this project. A passive capacitive parametric ultrasonic transducer (CPUT) can be suitable for these applications as it does not require a dc bias or a permanent charge. ... Guided by these results, practical device designs are obtained through COMSOL simulations. Finally, the feasibility of using the CPUT in air is predicted to set the foundation for.
