Flow function coefficient 意味
WebC v Calculator for Valve Sizing. This calculator can be used to help select a valve with enough flow capacity for a given application. The valve flow coefficient (C v) is a convenient way to represent flow capacity of a valve across a range of fluids and process parameters.The C v calculator will calculate either C v or flow using the supplied … WebThe canonical pressure coefficient is regarded by many as a better way to represent airfoil pressure distribution. The concept was introduced by A.M.O. Smith [7] to evaluate the adverse pressure gradient (dp/dx) and help determine the onset of flow separation.The approach scales the pressure coefficient, such it varies between 0 and 1. This is done …
