Abstract
Heat Exchanger has an important role in industry for successfull processes. The researches of heat exchanger focus on enhancement of heat transfer coefficient. Meanwhile the minimum pressure drop is also required to guarantee the subsequent process. Generally, those to requirements ae satisfied by the configuration of helical baffle. This work considers the helical baffle with different distance variation as well as mass flow rate inlet on the shell side. A CFD analysis is implemented for studying the variying distance of 0.15m, 0.1m, 0.075m, and 0.06m and with mass flow rate are 0.05kg/s, 0.1kg/s, and 0.2kg/s. The tube of staggered configuration is in triangular arrangement. In this research, turbulence model of k-ε realizable is used as a viscocity model, in parallel-flow configuration. The results show that the heat transfer coefficient is 469.05 W/m².K for 0.06 m distance and 0.2 kg/s inlet mass flow rate, the value of pressure drop is 46.47 Pa. It is concluded that the value between fluid flow and inlet mass flow rate is directly proportional with the value of heat transfer coefficient and pressure drop.
