Quenching characteristics based on the two-dimensional (2D) nonlinear unsteady convection-reaction-diffusion equation are creatively researched.The study develops a 2D compact finite difference scheme constructed by using the first and the second central difference operator to approximate the first-order and the second-order spatial derivative, Taylor series expansion rule, and the reminder-correction method to approximate Pacifier Cloth the three-order and the four-order spatial derivative, respectively, and the forward difference scheme to discretize Speaker Accessories temporal derivative, which brings the accuracy resulted meanwhile.Influences of degenerate parameter, convection parameter, and the length of the rectangle definition domain on quenching behaviors and performances of special quenching cases are discussed and evaluated by using the proposed scheme on the adaptive grid.It is feasible for the paper to offer potential support for further research on quenching problem.
