Numerical and Analytical Simulations of Nonlinear Time Fractional Advection and Burger’s Equations

Journal of Function Spaces, Volume 2022, Issue 1, 2022., 2022
In this paper, the higher nonlinear problems of fractional advection‐diffusion equations and systems of nonlinear fractional Burger’s equations are solved by using two sophisticated procedures, namely, the q‐homotopy analysis transform method and the residual power series method. The proposed methods are implemented with the Caputo operator.

Heat and Mass Transfer of the Darcy‐Forchheimer Casson Hybrid Nanofluid Flow due to an Extending Curved Surface

Journal of Nanomaterials, Volume 2022, Issue 1, 2022., 2022
The current paper describes a Darcy‐Forchheimer flow of Casson hybrid nanofluid through an incessantly expanding curved surface. Darcy‐Forchheimer influence expresses the viscous fluid flow in the porous medium. Carbon nanotubes (CNTs) with a cylindrical form and iron‐oxide are utilized to make hybrid nanofluids.

Effects of Homogeneous‐Heterogeneous Reactions on Maxwell Ferrofluid in the Presence of Magnetic Dipole along a Stretching Surface: A Numerical Approach

Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
The document is presented to investigate momentum and thermal attributes of Maxwell liquid flow over a stretchable surface by inducting ferrite particles along with taking account of homogeneous‐heterogeneous reactions. Two types of ferrite particles, namely, nickel zinc ferrite (NiZnFe2O4) and magnetite ferrite (Fe3O4), are considered and non ...

Approximate Analytical Study of Time‐Dependent MHD Casson Hybrid Nanofluid over a Stretching Sheet and Considering Thermal Radiation

Advances in Mathematical Physics, Volume 2022, Issue 1, 2022., 2022
The heat transfer ratio plays an important role in the production sector, and hybrid nanofluid has more heat transfer as compared to the base fluid. Two sorts of hybrid nanofluids have been used for heat enhancement applications. The present research paper is aimed at investigating an approximate analytical study of time‐dependent MHD Casson hybrid ...

The Optimal Homotopy Asymptotic Method for Solving Two Strongly Fractional-Order Nonlinear Benchmark Oscillatory Problems

Mathematics, 2021
This paper proceeds from the perspective that most strongly nonlinear oscillators of fractional-order do not enjoy exact analytical solutions. Undoubtedly, this is a good enough reason to employ one of the major recent approximate methods, namely an ...

Approximation of First Grade MHD Squeezing Fluid Flow with Slip Boundary Condition Using DTM and OHAM [PDF]

Mathematical Problems in Engineering, 2013
Summary: A steady two-dimensional axisymmetric flow of an incompressible viscous fluid under the influence of a uniform transverse magnetic field with slip boundary condition is studied. An ordinary nonlinear differential equation is formed by transforming the Navier-Stokes equations using the transformation \(\psi(r,z)=r^2G(z)\).

Optimal Homotopy Asymptotic Method for an Anharmonic Oscillator: Application to the Chen System

Mathematics, 2023
The aim of our work is to obtain the analytic solutions for a new nonlinear anharmonic oscillator by means of the Optimal Homotopy Asymptotic Method (OHAM), using only one iteration. The accuracy of the obtained results comes from the comparison with the
