In different energy conservation types, heat transfer improvement is a significant field that is directly connected to systems of economic efficiency. In this analysis, different twisted tape configurations are considered such as the augmentation thermal approach, the impact of various twisted tape parameters on the thermal performance of flow pattern, improvement of heat transfer are numerically conducted. The geometrical configurations used for this investigation include twisted tape thickness, twisted tape width, inward thickness and number of turns. The design of the technique of the experiment is used to investigate the effect of these parameters on hydraulic flow structure and enhancement of heat transfer. The Taguchi method is based on analysis of changes and performs the orthogonal arrays. Besides this, the orthogonal array of L16 is selected for this numerical work. The average percentage error between the experimental and computational fluid dynamics (CFD) outcomes for Nu number and friction factor are noted at about 6.5% and 4.5%. It is observed that the best twisted tape configuration design is obtained by applying CFD methodology compared with the Taguchi method to improve the heat performance using the performance evaluation factor (PEF) was more than 1.2. The maximum value of temperature differences and friction factor was for model 13. Moreover, the thermal performance was good as the values of PEF and the values of PEF are greater than 1.

Heaters are one of the central parts of natural gas reduction stations using turboexpanders to prevent the formation of hydrate and corrosion failure. This study intends to design a fired heater by applying a combustion sub-model to derive an optimal model for this kind of application. This model is developed to accurately consider all subsections of the fired heater namely radiation, convection, and shield sections, as well as flue gas composition, and its volume. Within this context, a multi-objective optimization is employed to identify the optimal design of the gas-fired heater in the natural gas reduction station for the Ramin power plant case study. The total economic and environmental costs, together with modified exergy efficiency, are selected as objective functions. Multi-criteria-decisionmaking-method is employed on Pareto frontiers optimal curve to suggest the optimal solution. Results show that the developed model can outperform previous models in thermal efficiency with relatively similar costs. Besides, the optimal point in Pareto suggested by the decision-making-method accounts for a higher modified exergy efficiency (1.3%) than the counterpart, which thermal efficiency is regarded as an objective function. At the same time, its total cost remained almost constant. The effects of changes in each of the design parameters on the objective functions are also evaluated.
