Dynamics of Unsteady Fluid-Flow Caused by a Sinusoidally Varying Pressure Gradient Through a Capillary Tube With Caputo-Fabrizio Derivative
(Vinca inst Nuclear Sci, 2023) Perveen, Zahida; Zainab, Iqra; Akram, Ghazala; Abbas, Muhammad; Baleanu, Dumitru; Sadaf, Maasoomah
This paper presents a study of the unsteady flow of second grade fluid through a capillary tube, caused by sinusoidally varying pressure gradient, with fractional derivative model. The fractional derivative is taken in Caputo-Fabrizio sense. The analytical solution for the velocity profile has been obtained for non-homogenous boundary conditions by employing the Laplace transform and the finite Hankel transform. The influence of order of Caputo-Fabrizio time-fractional derivative and time parameter on fluid motion is discussed graphically.

Optical Solitons for Lakshmanan-Porsezian Equation With Kerr Law Non-Linearity Using Improved Tan(ψ(η)/2)-expansion Technique
(Elsevier, 2021) Sadaf, Maasoomah; Dawood, Mirfa; Baleanu, Dumitru; Akram, Ghazala
The Lakshmanan-Porsezian-Daniel (LPD) equation, with spatio-temporal dispersion as well as group velocity dispersion, is investigated to retrieve new optical solitons. Abundant bright, dark, singular, kink and periodic optical solitons solutions of the LPD equation are constructed for Kerr law of non-linearity by improved tan (psi(eta)/2) method. Some of the obtained solutions are graphically illustrated using 3D-surface plots and the 2 corresponding 2D-contour plots. The novelty of the constructed solutions is established by comparison of the obtained results with the results available in the literature for LPD equation which shows the effectiveness of the improved tan (psi(eta)/2)method.

Solitary Wave Solutions To Gardner Equation Using Improved (ω(sic)/2 ) Tan 2 -Expansion Method
(Amer inst Mathematical Sciences-aims, 2023) Sadaf, Maasoomah; Dawood, Mirfa; Abbas, Muhammad; Baleanu, Dumitru; Akram, Ghazala
In this study, the improved tan(Omega(sic)/2 )-expansion method is used to construct a variety of precise soliton and other solitary wave solutions of the Gardner equation. Gardner equation is extensively utilized in plasma physics, quantum field theory, solid-state physics and fluid dynamics. It is the simplest model for the description of water waves with dual power law nonlinearity. Hyperbolic, exponential, rational and trigonometric traveling wave solutions are obtained. The retrieved solutions include kink solitons, bright solitons, dark-bright solitons and periodic wave solutions. The efficacy of this method is determined by the comparison of the newly obtained results with already reported results.
