The Effect of Baffle Type and Fluid Mass Flow Rate Ratio on Shell and Tube Type Vertical Condenser

Condenser is a heat exchanger in which there is a phase change in it, from the vapor phase to the liquid phase. One type of condenser that is widely used is the shell and tube type, both horizontally and vertically. The authors do research about vertical condenser in laboratory scale to find the value of overall heat transfer coefficient, effectiveness, pressure drops in shell side, and discharge and temperature of produced condensate. The authors make variation of 4 baffle types and 3 fluid mass flow rate ratios between hot and cold fluid. The result is the value of overall heat transfer coefficient, effectiveness, and pressure drop increase as the cold fluid discharge increase. Single segmental baffle produces the highest value of overall heat transfer coefficient by 158.200 W/m2. ℃, and the highest effectiveness value of 0.856 at cold fluid discharge of 2.2 GPM. There are no significant difference value of pressure drops because the authors do not apply the variation of baffle spacing. The three-quarter baffle 180° produces the fastest condensate discharge of 28.04 mL/min and the highest condensate temperature of 83.866°C. © 2024 American Institute of Physics Inc..
