A novel approach based on minimization for numerical solutions of Burgers’ equation

This paper deals with the numerical solution of Burgers’ equation. By using radial basis functions (RBFs), an optimization approach is used to derive the approximated solution. Furthermore, we use the regularization term to avoid the growth of RBF coefficients. Also, the stability of the proposed method is verified, and finally we present some numerical examples to confirm our given approach.

A stabilized FEM formulation with discontinuity-capturing for solving Burgers’-type equations at high Reynolds numbers

This computational study is concerned with the numerical solutions of Burgers’-type equations at high Reynolds numbers. The high Reynolds numbers drive the nonlinearity to play an essential role and the equations to become more convection-dominated, which causes the solutions obtained with the standard numerical methods to involve spurious oscillations. To overcome this challenge, the Galerkin finite element formulation is stabilized by using the streamline-upwind/Petrov–Galerkin method. The stabilized formulation is further supplemented with YZβ shock-capturing to achieve better solution profiles around strong gradients. The nonlinear equation systems arising from the space and time discretizations are solved by using the Newton–Raphson (N–R) method at each time step. The resulting linearized equation systems are solved with the BiCGStab technique combined with ILU preconditioning at each N–R iteration. A comprehensive set of test examples is provided to demonstrate the robustness of the proposed formulation and the techniques used.

The optimal a priori error estimates for the unknown and auxiliary variables in the L2Ω norm are derived by using the stability results. Finally, numerical results are given to verify the feasibility and effectiveness.

The presented scheme gives higher accuracy in terms of higher convergence in less CPU time, which has been illustrated through the test problem.

Computer modeling system for the numerical solution of the one-dimensional non-stationary Burgers’ equation

The computer modeling system for numerical solution of the nonlinear one-dimensional non-stationary Burgers’ equation is described. The numerical solution of the Burgers’ equation is obtained by a meshless scheme using the method of partial solutions and radial basis functions. Time discretization of the one-dimensional Burgers’ equation is obtained by the generalized trapezoidal method (θ-scheme). The inverse multiquadric function is used as radial basis functions in the computer modeling system. The computer modeling system allows setting the initial conditions and boundary conditions as well as setting the source function as a coordinate- and time-dependent function for solving partial differential equation. A computer modeling system allows setting such parameters as the domain of the boundary-value problem, number of interpolation nodes, the time interval of non-stationary boundary-value problem, the time step size, the shape parameter of the radial basis function, and coefficients in the Burgers’ equation. The solution of the nonlinear one-dimensional non-stationary Burgers’ equation is visualized as a three-dimensional surface plot in the computer modeling system. The computer modeling system allows visualizing the solution of the boundary-value problem at chosen time steps as three-dimensional plots. The computational effectiveness of the computer modeling system is demonstrated by solving two benchmark problems. For solved benchmark problems, the average relative error, the average absolute error, and the maximum error have been calculated.

An efficient scheme for numerical solution of Burgers’ equation using quintic Hermite interpolating polynomials

A numerical scheme combining the features of quintic Hermite interpolating polynomials and orthogonal collocation method has been presented to solve the well-known non-linear Burgers’ equation. The quintic Hermite collocation method (QHCM) solves the non-linear Burgers’ equation directly without converting it into linear form using Hopf–Cole transformation. Stability of the QHCM has been checked using Eucledian and Supremum norms. Numerical values obtained from QHCM are compared with the values obtained from other techniques such as orthogonal collocation method, orthogonal collocation on finite elements and pdepe solver. Numerical values have been plotted using plane and surface plots to demonstrate the results graphically.

Numerical solution of Burgers’ equation with high order splitting methods

In this work, high order splitting methods have been used for calculating the numerical solutions of Burgers’ equation in one space dimension with periodic, Dirichlet, Neumann and Robin boundary conditions. However, splitting methods with real coefficients of order higher than two necessarily have negative coefficients and cannot be used for time-irreversible systems, such as Burgers’ equations, due to the time-irreversibility of the Laplacian operator. Therefore, the splitting methods with complex coefficients and extrapolation methods with real and positive coefficients have been employed. If we consider the system as the perturbation of an exactly solvable problem (or one that can be easily approximated numerically), it is possible to employ highly efficient methods to approximate Burgers’ equation. The numerical results show that both the methods with complex time steps having one set of coefficients real and positive, say ai∈R+ and bi∈C+, and high order extrapolation methods derived from a lower order splitting method produce very accurate solutions of Burgers’ equation.

Abstract Firstly in this article, the exact solution of a time fractional Burgers’ equation, where the derivative is conformable fractional derivative, with dirichlet and initial conditions is found byHopf-Cole transform. Thereafter the approximate analytical solution of the time conformable fractional Burger’s equation is determined by using a Homotopy Analysis Method(HAM). This solution involves an auxiliary parameter ~ which we also determine. The numerical solution of Burgers’ equation with the analytical solution obtained by using the Hopf-Cole transform is compared.

Numerical solution of Burgers’ equation by cubic Hermite collocation method

Abstract In this paper, numerical solution of the non-linear Burgers’ equation are obtained by using cubic Hermite collocation method (CHCM). The advantage of the method is continuity of the dependent variable and its derivative throughout the solution range. A linear stability analysis shows that the numerical scheme based on Crank–Nicolson approximation in time is unconditionally stable. This method is applied on some test problems, with different choice of collocation points to validate the accuracy of the method. The obtained numerical results show that the method is efficient, robust and reliable even for high Reynolds numbers, for which the exact solution fails. Moreover, the method can be applied to a wide class of nonlinear partial differential equations.

Numerical solution of Burgers’ equation with modified cubic B-spline differential quadrature method

In this paper, a new numerical method, “modified cubic-B-spline differential quadrature method (MCB-DQM)” is proposed to find the approximate solution of the Burgers’ equation. The modified cubic-B-spline basis functions are used in differential quadrature to determine the weighting coefficients. The MCB-DQM is used in space, and the optimal four-stage, order three strong stability-preserving time-stepping Runge–Kutta (SSP-RK43) scheme is used in time for solving the resulting system of ordinary differential equations. To check the efficiency and accuracy of the method, four examples of Burgers’ equation are included with their numerical solutions, L2 and L∞ errors and comparisons are done with the results given in the literature. The proposed method produces better results as compared to the results obtained by almost all the schemes available in the literature, and approaching to the exact solutions. The presented method is seen to be easy, powerful, efficient and economical to implement as compared to the existing techniques for finding the numerical solutions for various kinds of linear/nonlinear physical models.

The advantages of the resulting method are algorithmic simplicity, parallel computation, easy handling of complicated boundary conditions, so it is very easy to implement and deal with more complex problems.

The initial approximation can be freely chosen with possible unknown constants which can be determined by imposing the boundary and initial conditions. Convergence of the solution and effects for the method is discussed. The comparison of the HAM results with the Homotopy Perturbation Method (HPM) and the results of [E.N. Aksan, Appl. Math.
