Natural and exact sciences are based on functional relationships between different variables. If these functional relationships meet certain criteria, they can be studied by using pro

Generalities Concerning the Optimal Control Problemson . shortly presents various ways of formulating optimal control problems and the main methods used to solve them. Some qualitative characteristics of these methods, accompanied by comparisons and criticisms, are included.

Dynamic Programming (Bellman Method)o complex optimal control problems. A brief introduction into dynamic programming is presented in this chapter.Dynamic programming is one of the most popular optimization methods. Its wide usage is explained by the fact that it can be used to solve a large diversity of problems, ranging from common

Heat Transfer Processesost work associated with the heating process are presented. The minimum entropy generation is generally not equivalent to the minimum lost available work. Two optimal control problems are defined and solved for various heat transfer mechanisms among which Newtonian heat convection and radiative heat

Both procedures show that, whatever the optimization criterion, parallel flow heat exchangers can not be optimal but counter-flow dev

Storage of Thermal Energy and Exergyd here is the minimum exergy destruction. All relevant irreversibility sources are considered. Every operation regime has an optimum charging time, which increases by decreasing the hot gas inlet temperature. Also, there is an optimum gas mass flow rate that makes the exergy destruction number a . T
