Abstract

Heat exchanger is a device with a heat transfer process between two fluids of different temperatures, separated by the solid wali and the heat transfer techniques diverse. Heat exchanger types shell and tube are the types of heat exchanger which are widely used in industry as the most efficient. Effectiveness analysis is done to see performance of the heat exchanger is operating optimally. It can be decreased due to the use of age, fouling factors, and the heat transfer coefficient decreased. The purpose of the research is to assess the effectiveness of heat exchangers that use by company and then compare them based on analytical and simulation results, assess the results of simulation based on variations in the flow direction parallel and the flow direction opposite to the effectiveness of heat exchangers, and reviewing the results of a simulation based on the variation of tubes number in heat exchanger. Effectiveness analysis conducted theoretical and simulation to know the performance of heat exchanger is best using Autodesk Simulation CFD Software and enter the boundary conditions that occur in the model. The simulation was performed with a varieties of flow direction and the total of tube. So we can do the best perform for optimization heat exchanger design. The simulation performed with a variety of flow direction that started from counter-flow into parallel flow and the variation of tubes number which originally totaled 417 tube become 439 tube, so we can do the best optimization heat exchanger design. Design data and the value of the boundary conditions for analysis getting directly from field data. The result of theoretical calculations based on field data, effectiveness of heat exchanger is 51.14% with temperature input and output of hot fluid is (Th,i) 50.1 °C and (Th,o) 40.29°C, input and output of cold fluid is (Tc,i) 30.92°C and (Tc,o) 41°C. The calculation of simulated based on field data, effectiveness of heat exchanger is 40.45%, with temperature input and output of hol fluid is (Th,i) 50.1°C and (Th,o) 42.34°C input and output of cold fluid is (Tc,i) 30.92°C and (Tc,o) 36.65°C. In the calculation of the simulation data based on variation of flow direction, effectiveness of heat exchanger is 61.9% with temperature input and output hot fluid is (Th,i) 50.1°C and (Th,o) 38.21 °C input and output cold fluid is (Tc,i) 30.92°C and (Tc,o) 32.46°G. In calculation of the simulation based on total variation of tube, effectiveness of heat exchanger is 63% with temperature input and output of hot fluid is (Th,i) 50.1°C and (Th,o) 38°C input and output of cold fluid is (Tc,i) 30.92°C and (Tc,o) 36°C. There are differences result about effectiveness of heat exchanger b^tween theoretical and simulation results. From the results of this research, we can conclude that effectiveness of heat exchanger would be better i f we change the inflow of cold fluid , and also increase total o f tube so the area of heat transfer become more wider. Important to recalibration of measuring instruments and heat exchanger components because there are differences result about effectiveness between theoretical and simulation results based on field data.
