Experimental and numerical simulation as a calibration measure of a venturi tube

The development of experimental theories has been the normal practice for studying hydraulics and fluid dynamics. Based on the fundamental equations some simplifications are included and through laboratory experimentation many of the relationships that are currently applied have been obtained. With the advancement of technology, the numerical simulation of the government equations has taken an important role in complementing the existing theories. However, it also has a certain level of simplification, so it has not been able to fully replace laboratory experimentation. A combination of both types of analysis, based on fundamental principles (theory), is necessary to obtain reliable results. In the present study, a theoretical, experimental and numerical analysis is applied to the case of flow in a Venturi tube determining that there is a high concordance when the results obtained with each of the methodologies are compared. With this, a reliable methodology is defined to analyze complex fluid flow problems.
