Developing Clean Technology through Approximate Solutions of Mathematical Models
In this paper, the role of mathematical modeling in the development of clean technology has been considered.
One method each for obtaining approximate solutions of mathematical models by ordinary differential equations
and partial differential equations respectively arising from the modeling of systems and physical phenomena has
been considered. The construction of continuous hybrid methods for the numerical approximation of the solutions
of initial value problems of ordinary differential equations as well as homotopy analysis method, an approximate
analytical method, for the solution of nonlinear partial differential equations are discussed
Solution of fractional order partial differential equations by discrete homotopy perturbation method
Bu çalışma, lineer ve lineer olmayan zaman kesirli mertebeli kısmi diferensiyel denklemleri çözmek için
ayrık uzak biçimli ayrık homotopi perturbasyon metodunu geliştirmiştir. Kesirli mertebe türevler Caputo
anlamında göz önüne alınmıştır. Bu metodun başarısı ve uygulanabilirliği bazı örnek problemler ile
gösterilmiştir. Elde edilen sonuçlar kesirli mertebe bir olduğunda, tam çözümler ile iyi bir uyumluluk
göstermiştir. Bu çalışmada gösterilen metodun kesirli mertebe hesabındaki benzer problemleri çözmesi
beklenmektedir.This work is developed the discrete homotopy perturbation method with a space discrete version to
solve the linear and nonlinear time derivative fractional partial differential equations. The fractional
derivatives are considered in the sense of Caputo. The success and applicability of this method has been
demonstrated by some sample problems. When fractional order is unit, obtained results are good
agreement with the exact solutions. The method demonstrated in this study is expected to solve similar
problems in fractional calcul
