“…Although the study analyzed the feasibility of the optimization method, blade velocity vector diagram, blade pressure diagram and fan performance curve, the optimization and analysis of fan parameters were not accurate enough for the engine cooling fan design. These issues have been discussed by [20], where a vehicle cooling system with front-end intake air volume was found to be affects directly on the aerodynamic resistance and heat dissipation performance of engine compartment, but the computational fluid dynamics (CFD) used method was not able to optimize the fan speed.…”

Recently, engine design and control systems have been developed using data-driven modeling techniques to specify the in-cylinder complicated combustion process. The cooling fan performance is highly influenced by several factors that are determined based on what is called (DOE) «design of experiments». These factors include blade tip clearance, pitch angle, distance from radiator. This work presents a method to improve a cooling fan performance of an engine by designing a Six Sigma technique using Control, Improve, Analyze, Measure, and Define (CIAMD). First, let’s assess the existing cooling fan performance and define its problem. Then, let’s specify the parameters that affect on fan performance to be optimized. Next, let’s conduct sensitivity analysis and evaluate manufacturing control of the developed cool Fan. The primary fan does not distribute air enough by the radiator to maintain the machine cool throughout hard circumstances. First, the work demonstrates how to develop an experiment to examine the influence of three performance elements: blade pitch angle, blade-tip clearance, and fan distance from the radiator. In order to improve the performance of the cooling fan, Box-Behnken design is adopted for testing quadratic (nonlinear) effects. It then indicates how to predict optimal quantities for every element, to produce a technique that makes airflows above the objective of 1486.6 m3/h when utilizing experimental measurements. Finally, it reveals how to operate simulations to confirm that this method creates airflow based on the specifications with more additional fans manufactured performance of 99.999 %. The results of S and X-bar control charts indicate that the manufacturing process is statistically under control

“…Many papers have revealed the relationship between thermal hydraulic characteristics and various fin structures, such as plate fin [1,13], strip fin [14][15][16][17][18], wavy fin [19], louvered fin [4,19], H-type fin, spiral fin, and slotted fin. Tao et al [19] found that the heat exchanger with larger wavy angles, smaller fin pitch and tube row number, has better heat transfer performance and higher pressure drop.…”

A numerical investigation is performed to study the thermal-hydraulic performances of tube-on-sheet heat exchanger. Especially, this paper is focused on the effects of the structure parameters (fin angles, fin lengths, fin pitches, fin widths and tube arc radius) on the thermal-hydraulic characteristics of the heat exchanger. The heat exchanger optimized structural parameters are obtained. The results reveal that main structure parameters on thermal-hydraulic performance are fin angle, fin length, fin pitch and fin width. Furthermore, decreasing the fin angle, fin pitch and fin width or increasing the fin length cause thermal hydraulic performance to increase. In addition, main structure parameters on low temperature corrosion are tube arc radius and fin length. Decreasing the tube arc radius and fin length can mitigate low temperature corrosion. Furth, stainless steel is choosing as the material for the heat exchanger to reduce corrosion.
