manufacturing across Canada. SlurryFlo Valve Corp. designs custom-engineered control valves for various_x000D_
flow conditions applied to a variety of industrial applications in the mineral processing, gas and petroleum, and_x000D_
power generation sectors and many other fields. With increasing demand for new, more effective valves, the_x000D_
company engineering group has observed a need to perform more advanced computational research on several_x000D_
critical flow modeling scenarios involving large-scale control valves. One of the critical issues in designing_x000D_
new large-scale valves (>30 inches) is an increase in the turbulence intensity of the flow passing through the_x000D_
valve and the occurrence of phase separation or segregation due to downstream recirculation zones past the_x000D_
valve. As a result, the turbulence and phase segregation significantly influence the so-called valve flow_x000D_
coefficient, which plays the governing role in valve design and in the selection of materials used in valve_x000D_
production. In this view, an accurate prediction of the valve flow coefficient taking into account the impact of_x000D_
turbulence is necessary for an optimal design of large scale valves. Calculations of this kind will help the_x000D_
company to make valves more reliable and more effective in terms of operation and production. In this work_x000D_
the flow coefficient of valves will be calculated directly using three-dimensional computational fluid dynamic_x000D_
models (3D CFD) under different flow conditions._x000D_
The innovative nature of this work lies in an adoptation of 3D CFD-based models (including a set of_x000D_
submodels and numerical schemes) available in the commercial solver ANSYS-Fluent to predict the flow_x000D_
coefficient of valves for single-phase and multiphase turbulent flows through valves of different sizes. The_x000D_
expected outcome from modeling single-phase and multi-phase flows through a valve will contribute_x000D_
significantly to enhancing the reliability and efficiency of engineered valves in a variety of industrial_x000D_
