“…The result of the first case of one tube and one pass heat exchanger as followings figures (9)(10)(11)(12)(13)(14). It is observed that in the temperature chart the temperature has lowest value in the inlet of the x direction nearly fixed and the then reached its maximum value after the mid of the heat exchanger.…”

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 (HXs) are indispensable devices used to exchange thermal energy in the form of heat transfer/dissipation between fluids (liquid or gas), from one medium to another [1,2]. Pipes are one of the most heavily stressed major components of HXs used in harsh working environments, such as power plant sectors, resulting in frequent premature failures.…”

Surface modification is essential to safeguard heat exchangers from premature failure spurred by deterioration mechanisms such as corrosion and wear, which diminish performance. Meanwhile, modifying some substrates with dissimilar materials is challenging due to a mismatch in material properties. Moreover, individual alloy coatings on substrates are usually insufficient in the required material properties, leading to accelerated failure of equipment, especially in power plant industries. This article summarised the knowledge base on functionally graded materials (FGMs) while emphasising how this promising class of novel materials can reduce deterioration. Additionally, laser cladding is established to be a suitable technique for processing FGMs. A particular focus is laid on the laser beam interaction with the FGM and expounding on the processing and material parameters that affect the microstructural properties of FGMs. The development prospects for processing FGMs with superior clad quality characteristics to increase boiler pipes' service life and performance are also highlighted.

“…The heat exchanger is a thermal medium that transfers heat between two or more fluids at different temperatures [1][2][3]. Heat exchangers are widely utilized in industrial applications such as chemical processing systems, waste heat recovery units, power plants, food processing systems, air conditioning systems, refrigeration, heating, and automobile radiators [2].…”

A new approach to optimize the design of a shell and tube heat exchanger (STHX) is developed via a genetic algorithm (GA) to get the optimal configuration from a performance point of view. The objective is to develop and test a model for optimizing the early design stage of the STHX and solve the design problem quickly. GA is implemented to maximize heat transfer rate while minimizing pressure drop. GA is applied to oil cooler type OKG 33/244, and the results are compared with the original data of the STHX. The simulation outcomes reveal that the STHX's operating performance has been improved, indicating that GA can be successfully employed for the design optimization of STHX from a performance standpoint. A maximum increase in the effectiveness achieves 57% using GA, while the achieved minimum increase is 47%. Furthermore, the average effectiveness of the heat exchanger is 55%, and the number of transfer units (NTU) has improved from 0.475319 to 1.825664 by using GA.
