Abstract:Manifold system is widely used in various heat exchange systems. The uneven distribution of branch flow is the basic problem of the manifold system. The uneven distribution of flow rate has a great influence on the pump power consumption of the manifold system. Therefore, Accurate prediction and optimization of traffic distribution within the system is crucial. In this paper, the common flat-panel solar collectors are analyzed to analyze the problem of uneven distribution of flow in the Manifold system. By using the classical fluid mechanics formula, the internal pressure, flow resistance and flow distribution are established by the continuity equation, conservation of energy and the law of conservation of momentum General mathematical model and C program to calculate the distribution of pressure and flow in the collector system and verify the experimental results. The results show that the flow distribution model can accurately predict the flow in the header system. The theoretical predictive model of collector flow pressure distribution has a wide range of applicability. It is of great significance to forecast the flow resistance, flow distribution and pressure distribution of industrial boiler systems, solar collector systems and various manifold systems. © 2018, Science Press.
