Efficiency Meets Affordability: Engineering A Cost-Effective Double Tube Heat Exchanger for Diverse Industries

Abstract

This project was dedicated to the meticulous design and construction of a double-tube heat exchanger, carefully engineered to optimize heat transfer between two process fluids through a multi-pass parallel flow configuration. In this design, water was chosen as the working fluid for both the inner and outer tubes, with the inner tube crafted from high-conductivity copper and the outer tube constructed from durable mild steel. This material selection was made to balance thermal efficiency with structural integrity and cost-effectiveness. To achieve an optimal design, a suite of advanced engineering software tools, including SolidWorks for 3D modeling, HTRI for heat exchanger analysis, and ANSYS for computational fluid dynamics (CFD) simulations, were employed. These tools enabled precise modeling and in-depth analysis, ensuring that the heat exchanger would meet stringent performance criteria. The simulation process involved varying key materials and process parameters, including tube diameter, wall thickness, flow rates, and inlet temperatures, to evaluate their effects on heat transfer efficiency and pressure drop. Different combinations of materials, such as aluminum and stainless steel for the outer tube, were also considered to identify the most effective configurations for different industrial applications. Detailed assessments of critical performance metrics, such as pressure drop, heat transfer coefficients, and overall thermal efficiency, were conducted using well-established correlations and data from authoritative sources in the field of heat exchanger design. Sensitivity analyses were performed to understand how variations in the material properties and process parameters impact the overall performance of the heat exchanger. Beyond the technical design, this project emphasized the practical implementation of a cost-effective solution that could be easily adapted to various industrial scenarios. The aim was not only to develop a heat exchanger that excels in efficiency but also to create a versatile and economically viable solution that can be integrated into a wide array of industrial processes. By balancing high performance with affordability, this project contributes to the advancement of sustainable and efficient thermal management systems across diverse industries.
