“…In some studies, numerical modeling was done for this purpose [4][5][6] and the effects of dimensionless geometrical parameters of the helically coiled tubes such as curvature ratio and coil pitch on the hydrodynamics and heat transfer characteristics were investigated. Artificial Neural Network (ANN), Adaptive Neuro-Fuzzy Inference System (ANFIS), and Genetic Algorithm (GA) are capable artificial intelligence methods for modeling, predicting and optimizing the performance of thermal systems.…”
