Abstract

This paper presents a numerical investigation into the fluid flow and heat transfer characteristics of a shell and tube heat exchanger (STHeX) equipped with baffles that induces swirl flow. A Computational Fluid Dynamics (CFD) model was created to simulate the STHeX behavior, and its accuracy was confirmed by comparing it to the Bell-Delaware method results. The two sets of calculations exhibited good agreement, validating the CFD model. The velocity component of the fluid flow was analyzed both qualitatively and quantitatively. The flow patterns of eddies on the STHeX were carefully examined and their correlation with thermal performance was investigated. This study demonstrates that the swirl flow baffle geometry leads to a more turbulent flow pattern, resulting in an increase in the overall heat transfer coefficient. The findings indicate that the swirl flow baffle enhances heat transfer performance and reduces pressure drop in comparison to a conventional STHeX.

Abstract

Green Mukti is a youth group founded by the Jatilor village government, Godong District, Grobogan Regency, with the aim of increasing the participation of the younger generation in the agricultural sector, especially in rice production, from planting to processing. However, over time, several problems have emerged, such as inconsistencies in the quality of production results or loss of rice raw materials due to errors in recording during harvest. Therefore, more effective monitoring is needed to ensure that the rice production process runs smoothly. One solution that can be applied is the development of a website with a Service Oriented Architecture (SOA) approach. SOA is an architectural style that offers benefits such as flexibility, reuse in various projects, and integration with various applications. With this service-based website, all stages of production can be monitored and controlled, thereby reducing errors, maintaining quality, and ensuring the availability of rice.
