Using longitudinal grooves has been proven to be an effective method for reducing drag on an axisymmetric boattail mode. In this study, a 3-layer ANN is used to predict the drag force of the model as the parameters of the groove change. The accurate values (determined by Ansys Fluent) show a difference of less than 2%, confirming the reliability of the artificial neural network used.
