Fundamental physical properties of multiphase microflows

Control of multiphase microflows is an important basic technology for integration of MUOs. Therefore, control methods for the stable phase separation of the multiphase microflows in a wide range of the flow 

In order to obtain the stress for phases I and II, integral calculus of Equation (4) is expressed as 

By substituting Equation (6) with Equation (7), the following relationship is obtained. 

From Equations (12) and (13), the flow velocity profile can be calculated. By integrating these equations along the x-direction, average velocities for phases I and II, (vj) and (vzu), are expressed as 

The volume flow ratio to achieve the width ratio of a/b is expressed as
