Set Trimming Procedure for the Design Optimization of Shell and Tube Heat Exchangers
In almost all previous approaches for the design optimization of shell-and-tube heat exchangers, global optimality was not guaranteed. Recognizing that the geometric components are discrete due to its physical nature (e.g., number of baffles) or commercial standards (e.g., tube diameter), purely integer linear models or mixed integer linear models using the Kern or the Bell-Delaware models were developed in previous work and solved globally using mathematical programming. The time used to solve these models was relatively small but still too large when repeated calculations are needed. We show in this article that the use of Set Trimming avoids using mathematical programming (MINLP or MILP) and reduces the computational time by at least 2 orders of magnitude.
