Numerical simulation and self-similar analysis of singular solutions of Prandtl equations
We use the iterative grid redistribution method(IGR) to
solve Prandtl equations and study the self-similar behavior of the singular solutions of them. The IGR method enables us to get more accurate solutions of Prandtl equations when they develop singularity. We also study the self-similar behavior of the singular solutions. Blow up rate and blow up profiles are derived and the results are verified by the numerical solutions.
