Numerical Modeling of the Electrohydrodynamics in a Hybrid Particulate Collector

摘要：

The specific gas flow influenced by the electrical field in the electrostatic precipitator (ESP) is called electrohydrodynamic (EHD) flow. The hybrid particulate collector (HPC) is a hybrid of the ESP and the bughouse in a unique approach combining the best features of both. The bags are placed between two perforated collection plates. The HPC is a very compact and high efficiency system.In this paper, numerical modeling of the three-dimensional EHD flow in a hybrid particulate collector (HPC) is presented. An unstructured finite volume method (FVM) was developed to solve the Poissons electrical equation and the current continuity equation within the collector. The Fluent code was used to solve the fluid N-S equations and the RNG k-ε turbulent model equations with considering the electrical body force. The numerical results show that the EHD flow can produce strong recirculation in the hybrid collector. Different from the ESP, the electric field has still strong influence on the gas flow when the EHD number below one.
