Wang also established a direct, quantitative and systematic relationship between flow distribution, pressure drop, configurations, structures and flow conditions and developed an effective design procedures, measurements, criteria with characteristic parameters and guidelines on how to ensure uniformity of flow distribution as a powerful design tool. The present models have been extended into more complex configurations, such as single serpentine, multiple serpentine and straight parallel layout configurations, as shown in Fig. Wang elaborated the most complete analytical solutions of Eq.2 - Eq.5. Their analytical solutions had been well-known challenges in this field for 50 years until 2008. The second term in the left hand represents a frictional contribution known as the frictional term, and the third term does the momentum contribution as the momentum term. Only under very slow laminar flow, Q 2 may be equal to Q 3.Įq.2 - Eq.5 are second order nonlinear ordinary differential equations for dividing, combining, U-type and Z-type manifolds, respectively. Our observations show that the greater the velocity (or momentum), the more fluid fraction through the straight direction. Obviously this disobeys our observations. Thus the velocities should be equal in two outlets or the flow rates should be equal according to the assumptions. 3, their resistances are same, R 2 = R 3. Since they have same diameter and length in Fig.
