Abstract: By using an improved variation constant method: B-mehtod, we studied approximation of the quenching solution and quenching time for a class of parabolic partial differential equation. We proved the existence of the numerical solution and validity of the method in solving quenching equation was proved by numerical simulation.

Key words: parabolic equation, quenching solution, B-method
