Optimization of the Design of Shell and Double Concentric Tube Heat Exchanger using the TLBO Algorithm

Abstract

Heat Exchangers are devices that allow energy in form of heat to be transferred between two or more fluids. HEs are utilized in a wide range of commercial processes, including chemical, steel, and power generation. Here, we focus on the optimization of shell and dual concentric tube HEs. This type of HE has been in use for many years because of their reliable service to enterprise, the availability of a set of symbols, and perfection in design and modeling, and they are made from a wide range of materials. In this paper a novel computative technique called TLBO Algorithm is used, and the aim is to lower the overall cost by designing the HE with a shell and two concentric tubes. For every iteration, the algorithm detects and replaces duplicate solutions in order to produce an effective functional evaluation, which may then be used to choose the best solution. With a usual start, it proves to be quite efficient, and therefore this algorithm will assist us in achieving our aim function, which is in contrast to conventional HEs. With GA based HEs with a shell and twin concentric tube HEs, the overall cost has decreased by roughly 43% and 34%, respectively.
