Convergence of generalized entropy minimizers in sequences of convex problems [PDF]
Integral functionals based on convex normal integrands are minimized over convex constraint sets. Generalized minimizers exist under a boundedness condition. Sequences of the minimization problems are studied when the constraint sets are nested. The corresponding sequences of generalized minimizers are related to the minimization over limit convex sets.

A mathematical model for entropy generation in a Powell-Eyring nanofluid flow in a porous channel
The continuous generation of entropy leads to exergy destruction which reduces the performance of a physical system. Hence, entropy minimization becomes necessary.
