In this study, different designs of the opening pattern of computer fan grills were investigated. The objective of this study was to propose a simulation analysis and compare it to the experimental results for a set of optimized fan designs. The FLUENT computational fluid dynamics (CFD) simulation software was used to analyze the fan blade flow. The experimental results obtained by the simulation analysis of the optimized fan designs were analyzed and compared. The effect of different opening pattern designs on the resulting airflow rate was investigated. Six types of fans with different grills were analyzed. The airflow velocity distribution in the simulated flow channel indicated that the wind speed efficiency of the fan and its influence were comparable with the experimental model. The air was forced by the fan into the air duct. The flow path was separately measured by analog instruments. The three-dimensional flow field was determined by performing a wind speed comparison on nine planes containing the mainstream velocity vector. Moreover, the three-dimensional curved surface flow field at the outlet position and the highest fan rotation speed were investigated. The air velocity distribution at the inlet and the outlet of the fan indicated that among the air outlet opening designs, the honeycomb shaped air outlet displayed the optimal performance by investigating the fan characteristics and the estimated wind speed efficiency. These optimized designs were the most ideal configurations to compare these results. The air flow rate was evenly distributed at the fan inlet.

This paper deals with an experimental analysis of stress prediction and simulation prior to 3D printing via the selective laser melting (SLM) method and the subsequent separation of a printed sample from a base plate in two software programs, ANSYS Addictive Suite and MSC Simufact Additive. Practical verification of the simulation was performed on a 3Dprinted topologically optimized part made of AISI 316L stainless steel. This paper presents a typical workflow for working with metallic 3D printing technology and the state-of-the-art knowledge in the field of stress analysis and simulation of printed components. The paper emphasizes the role of simulation software for additive production and reflects on their weaknesses and strengths as well, with regard to their use not only in science and research but also in practice.

Abstract In this paper, pure titanium (Ti) thin films deposited by radio frequency sputtering were used as a diffusion barrier layer in a flexible copper indium gallium selenium (CIGS) solar cell on a stainless-steel foil and characterized by X-ray diffraction, scanning electron microscopy and second ion mass spectroscopy measurement methods. The influences of the magnetron sputtering pressure on the surface morphology and preferred crystal orientation of Ti films are discussed. It was found that the Ti film showed a (001) preferred orientation and smooth surface topography at lower deposition pressure, while (002) preferred orientation and relatively rough surface topography at higher deposition pressure. In addition, Ti films made with different process pressures were deposited as the barriers and the second ion mass spectroscopy results indicated that a Ti film with the thickness of 200 nm was able to effectively block Fe and Cr diffusion from the stainless-steel foil into the CIGS absorber across the molybdenum back contact. The Ti barrier significantly improved the conversion efficiency of the CIGS solar cell.

Silicone dioxide (SiO2) layer as an electrical insulator and diffusion barrier was deposited on a flexible stainless steel substrate by plasma enhanced CVD process. And we deposited Mo/Na-doped Mo bi-layer back contact on the oxide layer in order to supply Na into the CIGS absorber. Then we deposited CIGS layer by three-stage process using elemental co-evaporation method and completed the solar cell fabrication. Without antireflection coating, the best CIGS solar cell on the stainless steel showed the conversion efficiency of 10.57 % with Jsc = 33.38 mA/cm2 and Voc = 0.519 V and FF = 0.61 for an active area of 0.45 cm2.
