Application of generalized differential quadrature rule in Blasius and Onsager equations

The generalized di.erential quadrature rule (GDQR) proposed recently by the authors is applied here to third-order non-linear di.erential equations of the Blasius type and to sixth-order linear Onsager di.erential equations. High (¿3rd)-order di.erential equations in ;uid mechanics are dealt with without using -point techniques. The half-space domain is simpli=ed in a practical way. Accurate results are obtained for both kinds of problems. The wide applicability of the GDQR in high-order di.erential equations is manifested further through this work
