Abstract:

In this manuscript, we study the blow-up phenomena of solutions for a class of viscous Cahn-Hilliard equation with gradient dependent potentials and source. We establish a criterion for blow-up and determine the upper bound for blow-up time by the energy method, the differential inequality and the derivative formula of the product; We determine the lower bounds for blow-up time by the differential inequality and the derivative formula of the product.

Key words: Viscous Cahn-Hilliard equation, Bounds for blow-up time, Criteria for the low-up, Differential inequality, Derivative formula of the product
