Significance of Arrhenius activation energy in flow and heat transfer of tangent hyperbolic fluid with zero mass flux condition

Abstract: The current endeavor scrutinizes the flow of tangent hyperbolic fluid over a moving stretched surface. The characteristics of heat transfer are conferred by utilizing nonlinear radiation. Further features of mass transfer are characterized with activation energy. The problem is modeled in terms boundary layer equations by implementing the relative laws. The independent variables in the governing equations through suitable transformations are reduced which are further tackled numerically via RKF-45 technique. Several physical parameters are varied in order to evaluate the behaviors of velocity, temperature and concentration distributions. It is established that higher values of We parameter increases the velocity profile. Further it is obtained that rate of heat transfer enhances as Nr parameter increases.

An Efficient Computational Technique for Fractional Model of Generalized Hirota–Satsuma-Coupled Korteweg–de Vries and Coupled Modified Korteweg–de Vries Equations

Abstract: The aim of the present investigation to find the solution for fractional generalized Hirota–Satsuma coupled Korteweg–de-Vries (KdV) and coupled modified KdV (mKdV) equations with the aid of an efficient computational scheme, namely, fractional natural decomposition method (FNDM). The considered fractional models play an important role in studying the propagation of shallow-water waves. Two distinct initial conditions are choosing for each equation to validate and demonstrate the effectiveness of the suggested technique. The simulation in terms of numeric has been demonstrated to assure the proficiency and reliability of the future method. Further, the nature of the solution is captured for different value of the fractional order. The comparison study has been performed to verify the accuracy of the future algorithm. The achieved results illuminate that, the suggested computational method is very effective to investigate the considered fractional-order model.
