Simulation of a three-dimensional model of the intake system of an agricultural tractor engine

Abstract

The paper defines the nature and parameters of the air flow after passing the throttle valve. This research problem was solved mathematically using a software package for modeling gas-hydraulic processes. The simulation was carried out using the FlowVision software package. For this purpose, using various standard file formats, the geometry was obtained and imported, which is understood as a three-dimensional model of the internal volumes of the engine-intake and exhaust pipelines, the over-piston volume of the cylinder, etc. This allows you to use the SolidWorks computer-aided design system to create a computational domain. For the area of calculation, the volume was adopted, in which the equations of the mathematical model and the volume boundary with the definition of boundary conditions were determined. The resulting geometry is saved in the format supported by FlowVision and used when creating a new calculation variant.
