| description | ObjectiveAn optimal design scheme for the inertial stage structure of the diesel engine intake filter is proposed, in order to meet the requirements of high separation efficiency and low resistance loss at the same time.MethodsFirst, taking the inertial stage of a diesel engine intake filter as the research object, a fusion blade structure was established by the natural fusion of groove and blade. Then, numerical simulation was used to calculate the droplet separation efficiency and resistance loss characteristics, and compare them with commonly used blade structure schemes at present. Finally, the inertial stage performance test of the intake filter was carried out, and the numerical simulation results were verified by the test results.ResultsThe simulation results and test results show that the fusion-type airfoil structure keeps the uniform and continuous distribution of the airflow velocity field and pressure field as much as possible while making full use of inertia to separate droplets, taking into account the requirements of separation performance and resistance performance. The overall performance of the design scheme is optimal. Under standard conditions, the droplet separation efficiency is close to 99.9%, and the resistance loss is about 42 Pa.ConclusionThe design scheme of the blade structure can provide a technical reference for the design of the inertial stage of the filter that takes into consideration the droplet separation efficiency and resistance loss performance. |
