Metering Research Facility Program. Numerical Simulation of the Flow Field Downstream of 90 Degree Elbows and the Simulated Response of an Ultrasonic Flow Meter

The study has resulted in information that can be used in determining the exact position to install a flow meter for optimum accuracy. The masters thesis of Karine Tung, "Numerical and Experimental Study on the Effects of Elbows Upon the Flow Downstream", comprises a major portion of the report.

Summary:
Flow meters are always installed somewhere in a piping system and are frequently preceded by elbows. The elbows alter the flow from fully developed flow and hence may cause a decrease in the accuracy of any flow meter installed downstream of the elbows. This study was undertaken in order to understand how elbows cause the flow in the pipe to deviate from a fully developed flow; to evaluate how far downstream of the elbows these effects persist; to estimate how adding a second elbow can modify the flow field; and to observe how the length of straight pipe between two elbows can affect the flow field. Both numerical and experimental studies were conducted for five different piping configurations. The study has resulted in information that can be used in determining the exact position to install a flow meter for optimum accuracy. The masters thesis of Karine Tung, "Numerical and Experimental Study on the Effects of Elbows Upon the Flow Downstream", comprises a major portion of the report.
