Homogeneous Equilibrium Model Used for Calculating Relief Area of Double Flow Safety Valve

Author has introduced thehomogeneous equilibrium model method that can be used for calculating the relief quantity of safety valve for both double phase and single flows according to the integral calculation in isoentropic process,author has also calculated the relief area of safety valve through a actual example of double phase flow,and has compared with the method of w factor method,the result indicates that two kinds of methods are fully consistent.
