Experimental Test The Effect Of Baffle Distance On The Thermal Enthusiasts And Decreased Pressure On Shell And Tube I-2 Pass Heat Exchanger
Experimental Test: The Effect of Baffle Distance on Thermal Performance and Decreased Pressure on the Shell and Tube I-2 Pass Heat Exchanger
Introduction
Heat exchangers are widely used in various industrial applications to transfer heat from one fluid to another. The design and performance of heat exchangers play a crucial role in determining their efficiency and effectiveness. One of the key factors that affect the performance of heat exchangers is the baffle distance, which is the distance between the baffles in a shell and tube heat exchanger. In this study, an experimental and theoretical test was conducted to determine the effect of baffle distance on the thermal performance and decreased pressure on a shell and tube type heat exchange device with a 1-2 pass configuration and a triangular tube arrangement.
Background
Heat exchangers are used in various industries such as chemical, petroleum, and power generation to transfer heat from one fluid to another. The performance of heat exchangers is affected by several factors including the baffle distance, tube arrangement, and fluid flow rate. The baffle distance is a critical parameter that affects the heat transfer coefficient and pressure drop in a shell and tube heat exchanger. A proper baffle distance setting can increase fluid turbulence, which contributes to increased heat transfer.
Experimental Setup
The experimental test was conducted using a shell and tube heat exchanger with a 1-2 pass configuration and a triangular tube arrangement. The heat exchanger was tested using a segment baffle with a baffle slaughter of 23.85%. The test was carried out with different variations of baffle distances, namely 36 mm, 40 mm, 45 mm, 51 mm, 59 mm, and 71 mm. The test results were measured using a thermocouple and a pressure gauge.
Analysis of Test Results
The test results show that the 45 mm baffle distance produces the minimum heat transfer coefficient measured by the Nusselt (NU) number and the minimum pressure decrease measured by the friction factor (FI). This indicates that the placement of appropriate baffles can increase fluid turbulence, which contributes to increased heat transfer. The results of the study also found an empirical correlation between the nusselt number (NU) and the friction factor (FI), which can be explained by the equation:
- ** NU = 0.1015 RE^0.63 **
- ** fi = 4,1728 RE^-0.281 **
With the range of Reynolds (RE) between 98.46 to 37645.5. This shows that there is a significant relationship between fluid flow and heat transfer efficiency in heat exchange devices, where the higher the Reynolds number, the more efficient the heat transfer process that occurs.
Discussion
The results of this study provide valuable insight for engineers and designers of heat exchange systems in an effort to improve energy efficiency and system performance. The study shows that the exact baffle distance setting is very important in the design of the Shell and Tube heat exchanger. Baffle distance of 45 mm is proven to be optimal in increasing thermal performance and reducing pressure reduction, so it is recommended for practical applications.
Conclusion
This study concluded that the exact baffle distance setting is very important in the design of the Shell and Tube heat exchanger. Baffle distance of 45 mm is proven to be optimal in increasing thermal performance and reducing pressure reduction, so it is recommended for practical applications. This study provides valuable insight for engineers and designers of heat exchange systems in an effort to improve energy efficiency and system performance. With a better understanding of the factors that affect heat transfer and decrease in pressure, it is expected that better design can be applied to various industrial applications.
Recommendations
By applying the results of this study, the industry can design a more efficient system, which in turn can reduce operational costs and increase energy sustainability. The study recommends that the baffle distance of 45 mm be used in the design of Shell and Tube heat exchangers to achieve optimal thermal performance and reduced pressure reduction.
Limitations
This study has several limitations. The study was conducted using a specific type of heat exchanger and fluid flow rate, which may not be representative of all heat exchanger applications. Additionally, the study only considered the effect of baffle distance on thermal performance and decreased pressure, and did not consider other factors that may affect heat transfer and pressure drop.
Future Work
Future studies should investigate the effect of other factors on heat transfer and pressure drop in heat exchangers, such as tube arrangement, fluid flow rate, and heat exchanger configuration. Additionally, studies should be conducted to validate the empirical correlation between the nusselt number (NU) and the friction factor (FI) found in this study.
