Design and Optimization of Heat Exchangers Using Nickel-Based Alloys in using COMSOL Multiphysics

الملخص

This article's primary goal is to provide a presentation on the validation of heat exchangers using nickel alloys that employ metaphysical COMSOL’s. The COMSOL program is used to simulate the operation of heat exchangers in power production systems, and it does so by using the comparative verification that you provided between the change in length and temperatures. Moreover, heat exchangers are an important component in power generation systems, where the task is to convert heat generated by fuel combustion, nuclear reactions, or by concentrating the output of solar collectors into mechanical energy. Heat exchangers simplify the processes that are at the heart of the equipment. Heat exchanger designs constrain the heat transfer patterns and fluid flow behavior that occur in the system. The COMSOL program was used to create a 3D finite element model of the heat transfer process. Experimental data was used to validate the model's predictions. By calculating the temperature equation for heat transmission along the metal, the simulation displays the heat transfer model together with the temperature distribution from 273.15 to 373.15 K, as well as the distribution of velocity (0 to 0.07 m/s) and length (0 to 15 cm) over time. The temperature equation was solved for heat transfer along the nickel, which experiences a pressure range of 0.02 to 3.12 Pa. Nickel was used for this test since it conducts heat more effectively than other metals. Because of its thin and lightweight nature, it is simple to design as an excellent refractory conductor
