“…As a common class of thermodynamic problems, quenching phenomena research has been widely applied in engineering area. There exist some typical researches including the flow, thermal properties, and its working mechanism of an object in heat associated with quenching phenomena [1,2], the forced convection quench of hot sheets in super-cooled liquid [3], the quench process speed-up, and its quench characteristics in porous interface processing [4,5]. In recent years, more and more scholars concern quenching problem built on parabolic equations [6][7][8][9][10], in which the authors depended on the different parabolic equations to analyze corresponding quench features.…”

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 the three-order and the four-order spatial derivative, respectively, and the forward difference scheme to discretize 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.
