This article is devoted to the method of numerical modelling of aerodynamics when the air flows around fins of a special design, which is implemented in SolidWorks Flow Simulation. The study was carried out for three types of rib orientation, and the aerodynamic drag coefficients were determined for different values of the Reynolds number. It was confirmed that the drag coefficient values depend significantly on the flow regime. The lowest value of the drag coefficient is observed when the fins are oriented from a larger diameter to a smaller one. In the laminar regime (Re < 2300), the average value of CX = 1.04, in the transitional regime (2300 < Re < 10,000), CX = 0.74, and in the turbulent regime (Re > 10,000), CX = 0.22. Characteristic for this case of orientation is a significant decrease in the drag coefficient during the transition from laminar to turbulent regime; the minimum is observed at the flow speed in the range between 2 and 3 m/s.

A heat exchanger is a tool used to move heat from one fluid to another without letting the fluids mix. The fluids can be liquids or gases, flowing in separate channels or passages separated by a solid wall. In order to get the cold fluid to the desired temperature, the heat exchanger converts thermal energy from the hot fluid to the cold fluid. They are commonly used in a number of businesses and industries to recover waste heat, cool or heat process fluids, and maintain or adjust temperatures. ANSYS Fluent software was used to model and simulate the heat exchanger in this investigation. The simulation results of the heat exchanger of velocity at the inlet and temperature at the outlet are 3.43 m/s and 3.4×10 2 K, respectively. The study aimed to understand better the heat exchanger's fluid flow and heat transfer properties to design it for better performance. A wide range of working situations was simulated, including various inlet velocities, outlet pressures, and temperatures. Experimental data were used to validate the simulation model, and the findings revealed good agreement between the two. For better findings, copper material was employed in the simulation in this study rather than aluminium in the work of other researchers. Copper is a better heat conductor than aluminium because it has a higher thermal conductivity. Because of this, it is a strong option for applications where heat transfer must happen swiftly and effectively. Copper is a superior material for applications that will be exposed to aggressive environments since it is more corrosion-resistant than aluminium. The simulation results were examined to determine how different factors affected the heat exchanger's output, including its heat transmission and fluid flow capabilities. The simulation was then used to improve the heat exchanger's design for improved performance.

A Hybrid Feature Selection Framework Using Improved Sine Cosine Algorithm with Metaheuristic Techniques

Feature selection is the procedure of extracting the optimal subset of features from an elementary feature set, to reduce the dimensionality of the data. It is an important part of improving the classification accuracy of classification algorithms for big data. Hybrid metaheuristics is one of the most popular methods for dealing with optimization issues. This article proposes a novel feature selection technique called MetaSCA, derived from the standard sine cosine algorithm (SCA). Founded on the SCA, the golden sine section coefficient is added, to diminish the search area for feature selection. In addition, a multi-level adjustment factor strategy is adopted to obtain an equilibrium between exploration and exploitation. The performance of MetaSCA was assessed using the following evaluation indicators: average fitness, worst fitness, optimal fitness, classification accuracy, average proportion of optimal feature subsets, feature selection time, and standard deviation. The performance was measured on the UCI data set and then compared with three algorithms: the sine cosine algorithm (SCA), particle swarm optimization (PSO), and whale optimization algorithm (WOA). It was demonstrated by the simulation data results that the MetaSCA technique had the best accuracy and optimal feature subset in feature selection on the UCI data sets, in most of the cases.
