Vertical Upward Flow Map 1
Provides a plot showing the flow regime map for a vertical upward two phase flow based on the work by Hewitt and Roberts (1969).
Information regarding the axes follows.
y-axis
rho_G j_G = vapor density multiplied by superficial gas velocity where
j_G = G*x/rho_G = superficial gas velocity
x-axis
rho_L j_L = liquid density multiplied by superficial liquid velocity where
j_L = G*(1-x)/rho_L = superficial liquid velocity
where
G = total mass flux (m_dot/A)
x = quality
