To solve the mystery of external aerodynamics a person had to step forward and that person was Prandtl with his work on Boundary Layer Theory from 1904 and forward. So that, at the beginning of the 20 th century a person of name H. Blasius gave rise to one of the original, and now classical solutions of the equation of Prandtl's Boundary Layer Theory. This project captures the solution of the boundary layer equations by applying it to the flow along a very thin flat plate at zero incidence. Is important to know that historically this was the first example illustrating the application of the Prandtl's boundary layer theory, such was discussed by H. Blasius back in 1908 in his doctor's thesis.
2 Problem Description This project captures the numerical solution of the boundary layer equations by applying it to the flow along a very thin flat plate at zero incidence. This involved solving the ordinary differential equation known as Blasius Equation ( ) by applying numerical methods such as Runge-Kutta Method for Systems of Differential Equations (RKMSDE), and Runge-Kutta-Fehlberg (R
