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. | ||||
