| Study on CAD technology of heat exchange equipment and HECAD system upgrade | An Wanhui | Heat exchange equipment is widely used in many industrial sectors such as petrochemical, oil refining, electric power, light industry, atomic energy, pharmaceuticals, and metallurgy. Its investment accounts for a large proportion of the total investment in various fields and is an important process industry equipment. CAD technology has entered the field of practical application worldwide. Heat exchange equipment CAD technology is the specific application of CAD technology in the field of heat exchange equipment. Computer-aided design, manufacturing and research and development of heat exchange equipment are also the development trend of the heat exchange equipment industry. The CAD system for heat exchange equipment in thermal systems (HECAD system for short) realizes the integration of R&D and process design, mechanical design, and component design of new high-efficiency longitudinal shell-side heat exchange equipment. The promotion and application of this system can not only achieve energy saving and consumption reduction, reduce equipment investment costs, and improve equipment design quality and design efficiency, but also shorten product development cycles, optimize heat exchange equipment design, reduce costs, and liberate engineering and technical personnel from heavy repetitive labor. Since the development of this system, it has achieved great success in the automatic drawing of two-dimensional graphics and assembly drawings of parts and components, and has played an important role in the design process of new high-efficiency longitudinal shell-side heat exchangers. | 10.7666/d.y782854 |
| Prediction of deposits on heat exchanger surfaces using a neural network approach | O. Rudenko, O. Bezsonov | This study presents a neural network (NN) approach to predict the following values: the heat transfer coefficient at points of interest during the operation of a plate heat exchanger (PHE), as well as the point in time when the lower permissible limit of the heat transfer coefficient is reached. In this approach, the neural network model replaces the complex mathematical modeling, which uses a system of differential equations and a heuristic coefficient matrix to calculate the flow rate of deposits on the PHE plates, which requires a lot of computing resources. Training of a feed-forward neural network (FFNN) on a small dataset simulated near a reference point obtained from industrial measurements showed that the coefficient of determination R2 = 0.99 (accuracy) for short-term predictions and operational evaluation of the heat transfer coefficient is adequate, since the NN is of static type. | 10.3303/CET23103117 |
