Methodology development for modeling of the diesel D-245 work process when converting it to gas using the FlowVision software complex
Abstract
The article discusses the modeling of the working process of the D-245 diesel engine running on natural gas. Computer simulation was carried out using the domestic FlowVision CFD module. All stages of model building are considered. These are the creation of a geometric model, the features of setting the movement of valves and pistons, the features of adapting the computational grid and the process of burning gas fuel. The results of the calculation are presented in the form of visualization, in numerical values and in graphical form. The results are of particular value when it is possible to observe the processes of intake, compression, combustion, power stroke and exhaust in real time, as well as to evaluate the numerical values of temperatures, pressures, speeds and other parameters. Comparative analysis of combustion processes at various excess air ratios has been carried out. Relevant diagrams have been received.
