dc.description.abstractA real-time flow measuring algorithm is developed for the open Venturi channel non-Newtonian flow measurement. Using a single level sensor reading at downstream of the open Venturi channel, a drilling-well return flow rate can be calculated in real time. The experiments are conducted with different flow rates with step changes in pump outlet flow rate. The Coriolis flowmeter readings used to validate the calculated flow rates based on the level sensors. Three levels sensors record the reading when channel at a horizontal inclination. The level sensors are located at upstream of the Venturi contraction, near to the Venturi contraction and after the Venturi contraction. The minimum error occurs from the level sensor located near to the Venturi contraction. The strong subcritical flow regimes give a less disturbance for real-time flow measurements. The 1dimensional flow model well employed subcritical flow than the supercritical flow. We recommend locating the level sensor near to the Venturi contraction, where the maximum subcritical flow occurs.en_US
