A different models of Shell-and-tube heat exchangers were designed by Ansys geometry & Solidworks to evaluate the best model for heat transfer and to calculate the difference in heat transfer in each model by investigated with numerically modeling. Each model for heat exchanger has different assumptions for first model one tube & one pass with tube length 3 meter, was made with 2 different cases (each case have the same conditions such as same temperature, same velocity, changing the direction of the flow between parallel and counter flow). The flow and temperature fields inside the shell and tubes are resolved using a Ansys CFD 17.2. A set of CFD simulations is performed for a single shell and tube bundle and is compared with the experimental results. the Realizable K-ε model is known for predicting the flow separation better than Standard K-ε. The temperature of each model is examined in detail. Each design was studied separately on the basis of the findings, the designs need modifications to improve heat transfer.The main goal of designing these models is to obtain highest performance for shell and tube heat exchanger with givien conditions. These studies were carried out to find the most suitable conditions of operation in shell and tube heat exchanger so that in the future it can improve the performance of heat exchanger in industries through applying these conditions. For future researches, the shell and tube heat exchanger the best case in performance will be chosen, then try to develop the shell and tube heat exchanger and reach maximum performance and efficiency of shell and tube heat exchanger. so that, in industries, the heat exchanger will be easier to be chosen based on the function and conditions required.

Heat exchangers are very useful equipment in a wide range of industries, therefore ?the analysis of the internal flow in them is very important. In this study, a heat exchanger is modeled to solve the flow and temperature field. Three ?turbulence models have been tested for first and second order discretization using ?two different mesh densities, and the results are as follows. The effects of different parameters on the internal conditions of the converter have ?been simulated. The temperature changes decrease in proportion to the reduction of ?the heat transfer coefficient in viscous fluids, and the Reynolds number is greater ?than the Parantel number. For the tube with constant wall temperature and shell inlet, the heat transfer ?coefficient, pressure drop values and heat transfer rate are obtained. In another part, it is shown that the stabilization time of the fluid temperature has a ?direct relationship with the heat capacity of the pipes, and that the performance of ?the tubular heat exchanger with spiral walls is better than that of segmental walls. The intermittent temperature input has been investigated. It has been shown that ?the other flux will fluctuate with the same frequency, which it also proved our ? theoretical results.

“…There are many other recent experimental or analytical work related to the evaluation of shell and tube type heat exchangers, where the effect of different baffles or cut baffles can be observed (WEN et al, 2015;AFSAR et al, 2018;CHAUHAN;BAROT, 2018;PÉTRIK;SZEPESI, 2018;MOHANTY, 2020;AYDIN et al, 2020;GUPTA;VERNA, 2022), or related to cost-energy optimization (WEN et al, 2016), or analyses of the performance optimizations of parameters using CFD (HANAN et al, 2021). There are also several mathematical models for heat exchangers; some are simple, e.g., Kern method, some are more comprehensive and consider details of the flow, e.g., Bell Delaware (KAKAÇ; LIU, 2002).…”

O presente estudo avalia, usando simulações numéricas em CFD, os efeitos da lacuna entre os orifícios das chicanas e o feixe de tubos no processo de transferência de calor em trocadores de calor de casco e tubos, especialmente em relação ao coeficiente convectivo médio no lado do casco. O fluxo de água no lado do casco foi simulado numericamente aplicando-se dois modelos de turbulência, ou seja, k – ε standard e k – ε EARSM (Explicit Algebraic Reynolds Stress Models). Os resultados obtidos em CFD para os valores dos coeficientes convectivos médios foram comparados com resultados da literatura e com resultados analíticos obtidos pelos métodos de Kern e Bell-Delaware, apresentando boa concordância quando as folgas entre os orifícios das chicanas e os tubos são nulas, principalmente para o caso simulado com o modelo de turbulência k – ε EARSM, validando o modelo numérico implementado para avaliações térmicas de trocadores de calor casco e tubos. O estudo mostra que os resultados para os coeficientes médios de convecção no lado do casco obtidos pelos métodos analíticos mencionados apresentam boa concordância com resultados obtidos em CFD, com erros inferiores a 3 %, apenas quando as folgas entre os tubos e os orifícios das chicanas são nulas ou muito pequenas, menores que 0,2 mm. Contudo, para folgas relativamente maiores, acima de 1 mm, acabam superestimando o coeficnete médio de convecção em mais de 14 %, mesmo para o caso do método Bell-Delaware, que prevê fatores de correção para ajustar influência de tais folgas.
