It is difficult to acquire or calibrate the discharge coefficient of averaging Pitot tubes, especially for large diameter pipes. Simulations and experiments were carried out to obtain the measurement characteristics at the situation where there are not enough long straight pipe to ensure the fully developed fluid. The goal of this paper is to do some preliminary numerical tests on acquiring or calibrating...
For the difficulties of obtaining the discharge coefficient of the Annubar Flowmeters at large diameters, some attempt were made to improve this meter based on the numerical simulation. Some researches were done on two flowmeters with different blockage ratio under the condition of fully developed fluid by using standard k-ε turbulence model. The measurement characteristics of both flowmeters, such...
