“…Numerical simulations are chosen to depict experimental data accurately. The same conditions as previous researchers [5][6][7] have been implemented in the present study. The Tri: Pave Meshing Scheme was used on the surface to construct a face mesh comprising irregular triangular mesh elements.…”

“…In addition, designing a distributor is very critical. In the nature of conventional distributors, it is usually assumed that the pressure of the distributor reduces the ratio of the pressure [3][4][5][6][7]. The new type of fluidisation system (Swirling Fluidised Bed) can perform in low bed pressure depends not only on the type of distributor, as in Figure 1, but also on the fluidised particles, the depth of the bed, the velocity of surface gas, the aspect ratio of the bed and the tolerable percentage of uneven distribution [2].…”

The term fluidisation refers to transforming a bed of particulate materials into a fluid by the action of a fluid passing across it. The use of an annular blade distributor known as a Swirling Fluidized Bed (SFB) in new applications may increase the efficacy of fluidisations on the bed. For this analysis, 30 blades were considered, and the results of varying the horizontal inclination angle of the blade distributors by 10, 12, and 15 degrees were analysed. The Computational Fluid Dynamics (CFD) simulation study was carried out in order to evaluate the pressure drop of the multi-stage fluidisation system could be evaluated. This research shows that a multi-stage fluidisation system results in energy conservation and maintains a highly efficient performance system. This research demonstrates that a 15° blade inclination angle with 30 blades may lower pressure without affecting performance, and for the velocity profile, it indicates velocity uniformity in fluidisation systems.

“…Finite Element Analysis (FEA) is a computer-aided engineering (CAE) tool used to analyze how a design reacts under real-world conditions. Useful in structural, vibration, and thermal analysis [6,7], FEA has been widely implemented by automotive companies. Based on the current wall mount bracket design available in the market, this study focuses on the effect of having different parameter values of the design structure.…”

Nowadays, most flat screen television (TV) come with a feature that allows users to mount the TV and it takes some effort on the user's part to attach the mount to the wall and the TV to the mount. Various TV wall mount designs available on the market with different dimensions, thicknesses, and materials may cause mechanical problems. This study aims to analyze the effect of the design parameters on the wall mounting bracket and evaluate the best design parameters for minimal mechanical defects. The validated 3D model is simulated using SolidWorks software. Different wall mount lengths, widths, thicknesses, and TV wall mount bracket designs are selected as factors in this study. Meanwhile, stress, displacement, and strain are selected as responses in this study. Statistical regression analysis analyzes the correlations between design parameters and mechanical defects. The analysis shows that 6 mm thickness, 430 mm length, and 160 mm width have the lowest stress, strain, and displacement. Design 3 is the best wall plate design to minimize stress and strain. To conclude, the results of this study could make the TV wall mount bracket a universal mounting for various weights of TVs.

The demand for increased performance both in the professional and amateur sectors and the inclusion of the bicycle in the city as a clean, silent, inexpensive, and healthy personal transport, is responsible for the technological growth of the industry. This study aims to analyze the effect of the design parameters on the bicycle crank arm and to find the best design value within the range for minimal defects. The strength of the structure design is significant to ensure the performance of the bicycle crank arms. To solve this problem, several design structures and parameters were studied. The selected parameters in this study are crank arm length, width, thickness, number of cranks spider, and rib design. Von-misses stress, strain, and displacement are selected as dependent variables. Aluminium Alloy 6061-T6 is the selected material in this study. The external load of 1000 N force was applied in the y-direction. The length analysis results show that 160 mm length, 30 mm width, and 10 mm thickness with five crank spiders and pocket design arm have the lowest stress, strain, and displacement. By bringing a new alternative to the crank's arm structure, the cost of the manufacture will be reduced. At the same time, it can help precisely improve the rigidity of producing complex 3D shapes.
