Abstract
The aim of this article is to study the bioconvection flow of Casson fluid over a vertically stretching sheet. Applying similarity transformations, the system of non-linear ordinary differential equations is obtained from the equations governing the flow. The significance of this study is solving these nonlinear ordinary differential equations by employing ANN (Artificial Neural Networks). In the trial functions, a multi-layer perceptron with customizable parameters (the biases and weights) is used. The Adam (Adaptive Moment Estimation) optimization algorithm is adopted to determine the adjustable parameters of the trial solution. The results of the current approach are validated by utilizing the shooting method in conjunction with the Runge–Kutta 4th-order method. It is observed that using a modest number of hidden neurons might give sufficient accuracy. However, the results suggest that the efficiency of artificial neural network-based methods improves as the number of neurons in the hidden layer of the neural network increases. It is noted that the skin friction coefficient, Nusselt number, and Sherwood number decrease as bioconvection Peclet number, bioconvection Schmidth number, and dimensionless bioconvection constant increase, whereas motile microorganism density increases.
