Fin Heat Exchanger" investigates the efficiency of louvered fin heat exchangers in comparison to traditional plate fin heat exchangers for various heat transfer applications. The research highlights the importance of optimizing louver angles and Reynolds numbers for enhanced heat transfer. Using MATLAB for theoretical analysis, the study calculates Colburn j-factors and f-factors across different louver angles and Reynolds numbers. These theoretical values are then compared to results obtained from numerical simulations conducted using ANSYS FLUENT. The findings reveal that louvered fin heat exchangers exhibit significantly improved heat transfer rates, particularly at lower Reynolds numbers. The study identifies a louver angle of 23 degrees as optimal for maximizing heat transfer performance. However, at higher Reynolds numbers and louvered angles beyond 23 degrees, overall heat transfer efficiency diminishes due to a decrease in the Colburn j-factor. This research contributes valuable insights into the design and operation of louvered fin heat exchangers, offering guidance for more effective and efficient heat recovery systems across various industrial sectors. your research employs a combination of CAD modeling and CFD analysis to evaluate and compare the performance of air-cooled finned-tube condenser designs using different refrigerants. The use of aluminum fins and the selection of appropriate turbulence models are crucial aspects of your study. Your findings can provide insights into optimizing the design and refrigerant selection for air conditioning systems to enhance their efficiency and heat rejection capabilities.
