Cost and Entropy Generation Minimization of a Cross-Flow Plate Fin Heat Exchanger Using Multi-Objective Genetic Algorithm In the present work, a thermal modeling is conducted for optimal design of compact heat exchangers in order to minimize cost and entropy generation. In thi... P Ahmadi,H Haj...
The LCOH indicatrix is mainly sensitive to geological parameters including permeability and depletion, operational parameters including injection temperature and load factor as well as technical inputs parameters including network length and expense, the efficiency of heat exchanger [46]. Sign in to ...
The larger water flow actually drives up the cost of the unit. Rather than supplying a rigid specification to all heat exchanger manufacturers, the engineer should have ex- plained the goal for the process stream. This could have been in the form of the following statement: “The ...

A heat exchanger is a single device, such as a heater, a cooler, and a condenser. It is also part of a process equipment, such as the heat exchanger in ammonia. Because of the limitation of manufacturing process and scientific level of the early heat exchanger can only use simple structur...
The objective function that gave an account to the weight of the heat exchanger provides the minimization of the size and the initial cost of the heat exchanger under the defined constraints, while the annual cost target yields the optimum pressure drops, considering the trade-off between energy ...
These conventional methods for heat exchanger design and development are time-consuming and expensive. Modelling, and in particular CFD simulation, has emerged as a cost-effective alternative that provides a quick solution in the design phase of HXs. CFD software is versatile and can be used to ...
