Different steps in the design process starting with the formulation and the concept have been presented to obtain acceptable designs followed by optimization. Many additional aspects that must be included in practice for a successful design have also been outlined. These include economic safety environmental regulatory legal and other issues that may be technical or nontechnical in nature. These considerations are of critical importance since a design that is technically feasible may not be acceptable because of the excessive cost or because it violates regulations regarding safety or the environmental impact. In this chapter we will consider knowledge-based design which is a non-tra-ditional design methodology based on experience informal approaches or heuristics information on existing systems and current practice. The main elements of this method and the overall scheme are outlined followed by examples of a few thermal systems to demonstrate the power and usefulness of this approach. Also considered are some additional important issues with respect to the design of thermal systems such as professional ethics and other constraints. Also discussed in this chapter are the sources of information that may be employed to provide inputs for design. Some of the important
