APPLICATION OF THE FINITE VOLUME METHOD TO CALCULATE THE WORKING PROCESS IN ICE

Галиев И. Р. Article language: English

Annotation

This article presents the theoretical and practical principles of CFD modeling of the temperature fields of an internal combustion engine when it operates in the crankshaft cranking mode. It was revealed, that to obtain reliable and accurate results, it is necessary to pay a great attention to the processes in the boundary layers of internal combustion engines and methods of their numerical modeling. A comparison of the calculated temperature values with the results obtained from the thermal calculation of the engine showed a discrepancy between the data of no more than 10 %, which indicates the correctness of the CFD calculation. The use of the Ansys Fluent software package makes it possible to carry out CFD modeling of the heat transfer process in the combustion chamber, taking into account the unsteadiness of this process and the movement of individual units of the cylinder-piston group, which is a significant advantage in the design of internal combustion engines. Keywords: finite volume method, CFD modeling, internal combustion engine, turbulence, SST model, workflow.
