The work concerns the computation of singular solutions of Navier-Stokes equations using the Chebyshev collocation method. A treatment of these singularities is necessary in order to preserve the accuracy of high-order methods. The authors employ the singularity subtraction technique which allows to compute a smooth solution after the subtraction of the leading part of singular solution.
