双通道养殖池流态模拟及验证
Numerical simulation and verification on flow-field distribution in ‘Cornell-type' dual-drain culture tank
摘要
Abstract
Culture tank is the critical equipment in the Recirculating aquaculture system ( RAS) , and as the basis for further research on two-phase flow, flow-field distribution in culture tank determines performance of culture tank. With the help of computational fluid dynamics (CFD) software, the flow-field distribution in the culture tank was simulated and verified by using the standard k - e model and RNG k - ε model, and get the velocity distribution of the flow field in culture tank . The results show that these velocities increased nearly linearly with radial distance from the tank center. Finally, by analyzed the simulation results and experimental datum, found that RNG k -ε model is better than the standard k -ε model on simulation results, and the simulation results are basically in agreement with the tank s operation law, numerical simulation has provided a new research method and mean to optimal structure designing and improvement.关键词
