Enhancing the heat transfer rate is an important factor in a heat exchanger. In Shell and tube heat exchanger, there is continuously requirement on improving the performance and effectiveness. The effect of various parameters like mass flow rate, inlet temperature on the overall heat transfer rate is studied. Based on the results obtained from the model developed parameters are optimized for better performance. In order to achieve this, many parameter is to be changed like flow of fluid, tube diameter, number of tubes, baffle arrangement, different types of baffles shapes and baffle spacing. This experiment is performed on the shell and tube heat exchanger for parallel fluid flow and the readings are taken. With this reading Overall Heat Transfer Coefficient for different flow rate is calculated by LMTD and NTU method and their results are compared. Also the model is prepared on Solidworks Software and CFD is performed on ANSYS R16.1 for one of the reading for parallel and counter flow and maximum value of wall heat transfer coefficient on hot and cold domain is obtained. Also number of baffles are added and all the results are compared to validate the design.
Shell and Tube Heat Exchanger Performance Analysis
2014
A heat exchanger is a device that is used to transfer thermal energy (enthalpy) between two or more fluids, at different temperatures and in thermal contact. In this problem of heat transfer involved the condition where different constructional parameters are changed for getting the performance review under different condition. An excel program has been developed for the ease of calculation and obtaining result after changing different parameters. The tube diameter, tube length, shell types etc. are all standardized and are available only in certain sizes and geometry. And so the design of a shell-and-tube heat exchanger usually involves a trial and error procedure where for a certain combination of the design variables the heat transfer area is calculated and then another combination is tried to check if there is any possibility of increasing the heat transfer coefficient. Since several discrete combinations of the design configurations are possible, the designer needs an efficient...

Optimization of Shell and Tube Heat Exchanger
A heat exchanger is a device, which transfer internal thermal energy between two or more fluids at different temperature. Without this essential piece of equipment most industrial process would be impossible. Heat exchangers are widely used in refrigeration air conditioning, and chemical plants. They can be employed in various uses, for instance, to effectively transmit heat from one fluid to the other. Shell-and-tube heat exchangers (STHXs) are widely applied in various industrial fields such as petroleum refining, power generation and chemical process, etc. Tremendous efforts have been made to improve the performances on the tube side.In this project experimental performance is done on the fixed designed STHX and calculate the heat transfer coefficient and effectiveness. Validation is to be carried out using which gives the result comparison with that of experimental result.Here flow parameters are not varied but size and number of tubes are varied and best efficient model is selected as Optimized value. 3 different number of tubes are used with same shell size remaining same. 40 tubes , 32 tubes and 36 tubes were tried . It's been observed for same input temperatures and mass flow rates for three different models one with 36 tubes , 32 tubes model &other with 40 tubes, the temperature variation in 36 tubes is more and also requires less tubes compared to 40 tube model. so it is more effective than tubes model.

Widely known that, heat exchanger is a device that is being used to transfer thermal energy (enthalpy) between two or more fluids, between a solid surface and a fluid, or between solid particulates and a fluid, at different temperatures and in thermal contact. The most common heat transfer devices are concentric tube (double pipe), shell and tube and, plate heat exchanger. Nowadays, Shell and tube heat exchangers were used extensively in most industries as petrochemicals, oil and refineries. According to previous survey, almost 45% of heat exchangers utilized are shell and tube heat exchangers due to its highpressure application it is more suitable in the field of oil & petrochemical application. Thus, the following study presented shell and tube type only. Due to complexity of studying heat exchangers experimentally, Computational Fluid Dynamics (CFD) used to simulate the effect of local surface heat transfer coefficients on the surfaces by aid of computer numerical calculation and graphical display.
