| Summary: | Background. This article describes a mathematical model of the acoustic path of
the ultrasonic method for measuring distances to a heated vertical plate, developed in the
geometrical-acoustics approximation. Based on the model, the factors influencing the
measurement of the propagation time of ultrasonic waves are identified. The purpose of the
work is an evaluation of applicability of the model for the development of ultrasonic pulse
echo measuring systems. Materials and methods. The model of the acoustic path is verified by comparing the numerical data with experimental obtained by the authors when modeling
the effect of various factors on the measurement results of the ultrasonic method. Results
and conclusions. As a result of the verification shows that the calculated data obtained using
the developed model, give good agreement with experimental data. The study lead to
the conclusion that the presented model can be used in the development of measuring systems
based on the ultrasonic echo-pulse method. |
