Abstract: Heat exchangers are utilized to transfer heat from the high temperature to the lower temperature. Whereas the helical coil tube in tube heat exchanger utilized to transfer heat in between two fluid at different temperature. Here in this work tube in tube helical coil heat exchanger is considered for the analysis. Here in this analysis hot fluid that is water is moving in the outer tube of the helical coil whereas the cold fluid water is flowing in the inner tube of the helical coil heat exchanger. Here we have analyzed the heat transfer at different mass flow rate of hot fluid and cold fluid. In order to analyze the effect of change in mass flow rate of hot fluid here we have picked up the three different mass flow rate of hot fluid while making the mass flow rate of cold fluid constant. After that to analyzed the influence of change in mass flow rate of cold fluid here we have considered the four different mass flow rate of cold fluid keeping the mass flow rate of hot fluid constant. To maximize the heat transfer rate here we have used the different variety of baffles inside the helical coil to maximize the heat transfer rate. To calculate the influencing of different geometry of baffles on the heat transfer here we have considered the two variated types of baffles that is semi-elliptical and rectangular shape. Through analysis it is found that the semi-elliptical shape baffle shows better result with respect to the other baffles. There we have calculated the heat transfer rate for each mass flow rate of cold and hot fluid, we have also calculated the logarithmic mean temperature difference for each case. Here we have also calculated the outcomes of friction factor for different baffles case.
