M. Lakdawala, C. V. J. Lakhera3 A, B C. Mechanical Engg. Department, Institute of Technology, Nirma University, Ahmedabad selected three design variables such as shell internal diameter, Abstract-- The present study explores the use of a non-traditional outer tube diameter and baffle spacing for optimization. optimization technique; Genetic Algorithm (GA), for optimization of steam surface condenser. The code for GA is I. DESIGN OPTIMIZATION METHOD developed and successfully applied for the optimization of same by varying the design variables such as shell internal diameter, Steam surface condenser is designed using a number of tube outer diameter, tube thickness and tube material. The objective function for capital cost is derived and same is used for design variables i.e. shell inner diameter, tube outer diameter, optimization. The optimized results obtained using GA are found tube thickness, tube pitch, tube layout angle, tube material to be superior to the earlier obtained results. and so on. The present study explores the use of Genetic Index terms—Surface condenser, Optimization, Genetic Algorithm (GA) to optimize the cost of steam surface algorithm condenser
