| 概要 |
A heat exchanger is a tool used to move heat from one fluid to another without letting the fluids mix. The fluids can be liquids or gases, flowing in separate channels or passages separated by a solid... wall. In order to get the cold fluid to the desired temperature, the heat exchanger converts thermal energy from the hot fluid to the cold fluid. They are commonly used in a number of businesses and industries to recover waste heat, cool or heat process fluids, and maintain or adjust temperatures. ANSYS Fluent software was used to model and simulate the heat exchanger in this investigation. The simulation results of the heat exchanger of velocity at the inlet and temperature at the outlet are 3.43 m/s and 3.4×10^2 K, respectively. The study aimed to understand better the heat exchanger's fluid flow and heat transfer properties to design it for better performance. A wide range of working situations was simulated, including various inlet velocities, outlet pressures, and temperatures. Experimental data were used to validate the simulation model, and the findings revealed good agreement between the two. For better findings, copper material was employed in the simulation in this study rather than aluminium in the work of other researchers. Copper is a better heat conductor than aluminium because it has a higher thermal conductivity. Because of this, it is a strong option for applications where heat transfer must happen swiftly and effectively. Copper is a superior material for applications that will be exposed to aggressive environments since it is more corrosion-resistant than aluminium. The simulation results were examined to determine how different factors affected the heat exchanger's output, including its heat transmission and fluid flow capabilities. The simulation was then used to improve the heat exchanger's design for improved performance.続きを見る
