At present, there exist several theoretical and experimental problems in engineering which are still unsolved. For nonlinear problems, it is mostly difficult to obtain closed-form solutions. With a small step size D x= 1 0 , the initial condition (x 0 ,y 0 ) can be marched forward to ( 1 1 ) 9.1 Introduction. Differential equations have wide applications in various engineering and science disciplines. It turns out that the 0,C1 The fully coupled nonlinear systems describing the total mass, momentum, thermal energy, mass diffusion, and microorganisms equations are reduced to a set of ordinary differential equations via a set of new similarity transformations. In applications, the functions usually denote the physical quantities whereas the derivatives denote their rates of alteration, and the differential equation represents a relationship between the two. We are committed to sharing findings related to COVID-19 as quickly as possible. A differential equation is an equation for a function containing derivatives of that function. examined the impact of nanofluid natural convection due to magnetic field in existence of melting heat transfer by means of CVFEM. A microsphere is used to measure the applied electric field due to the electrostriction effect. 4) Movement of electricity can also be described with the help of it. This method has been developed by employing a novel mesh-face integration method and an extrapolation method for evaluating pressure and shear stresses at the mesh faces, such as the first-order, ghost-cell, or ghost-fluid methods.

Offered by The Hong Kong University of Science and Technology. Due to vast range of application the investigations on this special issue were still scant. The detailed analysis illustrating the influences of various physical parameters such as the magnetic, squeezing, and chemical reaction parameters and the Schmidt and Prandtl numbers on the distributions of temperature and microorganisms as well as the skin friction and the Nusselt number was presented. Firstly, the simultaneous strategy based on the finite element is used to transform the differential and algebraic optimization problems (DAOPs) into large scale nonlinear programming problems. \nonumber \] Now, to determine our initial conditions, we consider the position and velocity of the motorcycle wheel when the wheel first contacts the ground. The present method is, in principle, advantageous over the conventional methods based on control volumes in that pressure and shear stress can be evaluated separately. 2) They are also used to describe the change in investment return over time. A brief version of the nonclassical symmetry method for partial differential equations is also included and the present survey provides a platform for researchers to apply this method to tackle nonlinear problems of Fluid Mechanics. introduced a network-wide pedestrian flow model based on the modified cell transmission model which describes the link flow as ordinary differential equations.

In the paper “Level-of-Service Based Hierarchical Feedback Control Method of Network-Wide Pedestrian Flow,” Z. Zhang et al. If the shear stress is appropriately evaluated, the fluid force can be accurately obtained by summing over the mesh faces, because the surface area vector components converge with increasing grid density while the surface area does not. Sometimes, it is difficult to estimate the shear stress accurately with this method by its complex shape. At the end, a comparison as a limiting case of the considered problem with the existing studies is made and found in good agreement. The aim of the special issue was to present recent advances at attempts to extend exact, semianalytic, and computational methods for mathematical models in science and engineering, in both the theoretical and applied aspects. 1.I NTRODUCTION The Differential equations have wide applications in various engineering … We also acknowledge the entire staff of journal’s Editorial Board for providing us with their support regarding this special issue. The applied electric field can be obtained by calculating these shifts. This method is used to solve differential equations having a sufficient number of symmetries and its application does not depend of the type of equation or the number of variables. It is observed that adding magnetic field makes the temperature gradient reduce due to domination of conduction mechanism in high Hartmann number.

In addition, it was also hoped that it will serve as a forum for presenting new and novel developments in the application of differential equations in several branches of science and engineering. Even a little increment of the ratio may cause higher variance between considering and not considering the rotary mass moment of inertia, especially for the high natural frequency.

APPLICATIONS OF DIFFERENTIAL EQUATIONS-ZBJ 1. Differential equations are fundamental importance in engineering mathematics because any physical laws and relations appear mathematically in the form of such equation… the capacitance of the circuit is linearly time-varying. The analysis of the thickness ratio shows difference between the classical K-L theory and N-T model when the ratio is greater than 0.099. Simulation on increasing values of the ratio of the shell shows impact of the N-T model especially on transverse stresses because of the significant energy contribution due to the third fundamental form tensor present in the kinematics of this model.
