Neural Network Representation for the Forces and Torque of the Eccentric Sphere Model

An artificial neural network (ANN) has been designed to simulate and predict the torque and force acting on the outer stationary sphere due to steady state motion of the second order fluid between two eccentric spheres by a rotating inner sphere with an angular velocity Ω The (ANN) model has been trained based on the experimental data to produce the torque and force at different eccentricities. The experimental and trained torque and force are compared .The designed ANN shows a good match to the experimental data.
