Abstract
The Blasius equation for laminar flow comes from the Prandtl boundary layer equations. In this
article, we establish a new and generic Blasius equation for turbulent flow derived from the
turbulent boundary layer equation that can be used for turbulent as well as laminar flow. The
analytical and numerical solutions have been investigated under specific conditions to the
developed new Blasius equation. The analytical and numerical results have been compared
through tables and graphs to validate the established model. In fluid dynamics, analytical solutions to complicated systems are tedious and time-consuming. Changing one or more constraints
can introduce new challenges. In this case, symbolic computation software provides an easier and
more flexible solution for fluid dynamical systems, even if boundary conditions are adjusted to
explain reality. Therefore, the MATLAB code is used to investigate the new third-order Blasius
equation. The comparison and graphical representations demonstrate that the achieved results
are encouraging.
