| Abstract: | A simulation model of the cooling airflow for armored vehicle engines has been developed,based on one dimensional transient compressible flow equations.The effects of flow passage geometry,wall friction,radiator transfer heat,fan work and branch flow on cooling airflow have been taken into account in the model.An exemplary simulation has been carried out for the cooling airflow of a tracked armored vehicle engine.This simulation model can be used as a theoretical analysis means for studying cooling airflow performance of armored vehicle engines. |
