Abstract

Air-intake filter in the ventilation system of offshore platform, is normally composed of the inertial stage and the multi-layer gauze stage, which plays an important role in providing sufficient and clean air. Numerical simulation and experimental research were carried on to study the flow field and resistance characteristics of the air-intake filter. Flow in the inertial stage was regarded as a 2D case, and the multi-layer gauze stage was simplified to an orthogonal array type. The quadratic polynomial of the resistance with velocity, and the permeability α and the pressure jump coefficient C2 of the composite stages were obtained on the basis of certain simplifications. By one source term added into the momentum equation, the flowing characteristics of the filter compounding the inertial stage and the gauze stage were computed based on the porous medium model. The simulating results of the total pressure loss are validated by the designed wind-tunnel experiment satisfactorily. The method was proved to be useful on the design and optimization of the air-intake filter on offshore platforms and other occasions.
