Abstract
ABSTRACT
This paper will present to the audience a processing and simulation method
regarding the theoretical approach of a mathematical model that describes the
phenomena taking place inside a new gas flow sensor. Because the working
principle of the flow sensor is a simple one – generating with a specific frequency
thermal pulses that transfer heat to the annular volume of gas and then, by
measuring the gas temperature evolved in time, determining the flow rate, a
mathematical model is needed to establish all the parameters that vary during this
process. This involved lot of mathematics for solving some parts of the established
model. The authors of this paper have proposed the specific software especially
developed for simulating the gas flow sensor. The software performs mathematical
prediction regarding the gas parameters after the generation of the thermal pulse
and the occurrence of heat exchange, more precisely, the evolution of gas speed,
temperature, density and pressure. These things are extremely important for the
development of this gas flow sensor, by comparing the experimental data with the
theoretical results.
