Microchannels based on microelectromechanical systems (MEMS) have received a lot of interest in the microfluidics and biomedical fields over the past forty years. While their applications have been multifarious, a comprehensive literature review focusing on their design, type, and applications is not currently present in the literature. Researchers working on these elements of microchannels will gain targeted knowledge from the current review on microchannels. Due to its advanced properties, flexibility of mass, and small size, microdevice demand has been rising quickly, particularly in industrial applications. The classification of microchannels and their uses are the main focus of this work. These include but are not limited to molding, electroplating, lithography, lab-ona-chip, micromolding, micromachining, micromilling, laser ablation, lithography, microcontact printing (µcp), hot embossing, electrochemical micromachining (EMM), and etching. In addition, numerous hybrid techniques for microchannel manufacturing have been reported. So, in essence, this review offers a range of advancements in microchannel manufacturing. The review also attempts to present a qualitative analysis describing the various methodologies associated with microchannels in terms of their design, shape, and flow regimes for applications such as pressure drop and transfer of heat prediction. Additionally, depending on the precise uses needed, a number of materials, including but not limited to ceramics, silicon, metals, and polymers, are utilized in the manufacture of microchannels. On metallic substrates, polymers such as silicon, glass, and polymeric materials are used. The biomedical industry uses polymeric and glass substrates instead of silicon substrates, which are used for mechanical engineering and electronic applications. In addition to outlining methods for choosing the best kind of microchannel, this paper also suggests important directions for the future.

“…There are different types of metaheuristic algorithms for optimization. They can be divided into four main groups (Nazari et al, 2022); evolutionary algorithms such as GA, swarm-based algorithms such as COA, human-based algorithms such as HS algorithm, and physics-based algorithms such as WCA. In this article, one metaheuristic algorithm was selected from each group to compare them in optimization of temperature fuzzy controller.…”

In this article, an experimentally validated new mathematical model is developed to show a vacuum box electric furnace’s thermal behavior and predict the temperature of the desired point inside it. The model is derived by extracting the equivalent electrical circuit of the system based on heat transfer principles. To show the accuracy of the model, its behavior has been evaluated by comparing it with experimental data. Then, an optimized fuzzy controller is designed using four metaheuristic algorithms, that is, genetic algorithm, harmony search, cuckoo optimization algorithm, and water cycle algorithm. The rule-base and the membership functions are optimized by these optimization algorithms with four criteria, that is, integral of absolute error, integral of square error, integral of time absolute error, and integral of time square error. The simulation results indicate that the fuzzy controllers tuned by the integral of time square error criterion get better performance, especially in genetic and water cycle algorithms. The designed controller based on the proposed model is implemented on an experimental setup. The experimental test shows a good agreement between experimental and simulation results. The obtained results show the ability of the fuzzy controller and approve that the developed model can be used for transient performance analysis of a vacuum box electric furnace and real-time controller design.
