%X This paper reports a high accurate solution of the Blasius function f (h) in the form of a converging Taylor’s series for a higher range of h 2 [0;9]. The method used consists of conversion of the boundary value problem into an initial value problem and solution by differential transform method. The initial value of the second derivative of the Blasius function is determined from the final value of first derivative of another function. The final value of first derivative of the latter function is determined by the Taylor’s series expansions with center at h = 15. The series expansion for the Blasius function is obtained with center of expansion at h = 4, is alternating and is accurately converging for higher values of h, with the number of used for summation equal to 2000. The present expansion is obtained without resorting to approximations and has a higher radius of convergence. The first 200 coefficients of the series, the second derivative of the function at h = 0, the parameters of the asymptotic solution are reported with 21 decimal places accuracy. The level of accuracy of the results presented is higher than any other results reported so far. This note also reports the mathematical steps involved in the derivation of the similarity variable of Blasius problem.
