WebStream function is a very useful device in the study of fluid dynamics and was arrived at by the French mathematician Joseph Louis Lagrange in 1781. Of course, it is related to the streamlines of flow, a relationship which we will bring out later. We can define stream functions for both two and three dimensional flows. WebStream function is a scalar function of space and time whose derivative with respect to any direction would give the velocity component at right angles to that direction. It is represented by ‘psi”, where The stream …
