Abstract

This project is regarding conduct static hole error analysis on Venturi Tube using CFD approach in order to having better visualization of this phenomenon. Based on the dimensionless analysis, relevant parameters to static hole error are identified and the effect of ratio of pressure tap depth to pipe diameter range 0.4, 1.0, 1.5, 2.0, 2.5 and 3.0 and ratio of pressure tap diameter to pipe diameter range 0.02, 0.04, 0.06 and 0.08 were simulated in both laminar and turbulent flow regime. The results were compared with journal paper´s results for validation with error of 1.86%. Besides that, results from static hole error analysis shows both hole diameter and depth of hole can influence the static pressure measurement.
