Vertical Upward Flow Map Toolbox Tab
A Toolbox Tab is available that implements the equations provided by Taitel et al. (1980) to create the flow regime map for a vertical upward two phase flow. The toolbox tab can be used if you have a Professional License of EES by downloading the .eestab file from the fchart website and then opening by selecting Open Tab when you right-click on one of the tabs. The specific flow map obtained by Vertical Upward Flow Map 2 is for an air-water mixture at room temperature and pressure in a 5 cm tube. The Toolbox Tab can be used to make a flow map that is relevant to any fluid and condition for a given tube geometry.
Information regarding the axes follows.
y-axis
superficial liquid velocity = G*(1-x)/rho_L
x-axis
superficial gas velocity = G*x/rho_G
where
G = total mass flux (m_dot/A)
x = quality
