Prediction of Natural Gas Wall-Impingement Spray Characteristics by ANN Model

In this study, the effect of injection pressure, impingement distance and angle, wall temperature on the macroscopic of wall impingement were investigated experimentally, predicted by using deep neural network in the MATLAB environment. With respect to obtaining data from experiments, input factors affecting impingement phenomena are trained, validated to develop model, which was applied to estimate output such as spray tip penetration and height. According to the results, the estimate parameters by coefficient of determination, root mean square error between 0.998 and 0.029. The ANN_GA model is found to be an effective tool to predict spray behaviors output with minimal experimentation.
