the effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Correcting a Coriolis Meter for Two Phase Oil & Gas Flow
It is also common for flowmeters to be installed downstream of a two or three phase separator. If the well conditions change or the separator has been incorrectly sized, then it is possible that the oil liquid outlet may have some gas carry under. The effects of gas entrainment on the output of ultrasonic and Coriolis meters has been reported previously [1] [2]. It is already known that gas ent...
متن کاملPressure, Temperature, and Other Effects on Turbine Meter Gas Flow Measurement
energy of a moving gas into rotational energy. At a given flow rate Q, the rotor of the turbine meter would spin at an angular velocity ωi as shown in Figure 1. With an idealized turbine meter, the rotational speed of the rotor would be directly proportional to the volumetric flow rate of the flowing medium. The relationship between flow rate Q and the angular velocity ωi can be expressed as fo...
متن کاملMulti Parameter Flow Meter for On-Line Measurement of Gas Mixture Composition
In this paper we describe the development of a system and model to analyze the composition of gas mixtures up to four components. The system consists of a Coriolis mass flow sensor, density, pressure and thermal flow sensor. With this system it is possible to measure the viscosity, density, heat capacity and flow rate of the medium. In a next step the composition can be analyzed if the constitu...
متن کاملComparison of the new miniature Wright peak flow meter with the standard Wright peak flow meter.
Preproduction and current models of the miniature Wright peak flow meter have been compared with the standard Wright peak flow meter on normal and abnormal subjects. Early problems in production appear to have been overcome, and the current model agrees to within 3% with the standard peak flow meter, which is as close as the agreement between two standard instruments. The new mini-meter may be ...
