Simulation based optimization of injection molding parameter for meso-scale product of dental component fabrication using response surface methodology (RSM)

This study examines the findings of numerical analysis studies that were conducted to determine how the arrangement of the blade distributors in a fluidization system affects the distribution of air flow distribution. In contrast to the conventional methods, which give the particle a swirling motion, the current fluidization systems produce a circular movement of a beds. Therefore, the influence of twist angle blade (60° and 100°) was investigated through to the horizontal inclination angle (15°) and radial inclination angle (10° and 12°) blade distributors. In a fluidization systems, the simulation was used to calculate and assess the performance outcomes of three velocity components: tangential velocity, axial velocity, and radial velocity. These components represent the flow of fluid inside the plenum fluidizations systems. According to the results of the numerical study that used a horizontal inclination of 15°, the velocity of the airflow in the fluidization systems may reach up to 8 m/s. This circumstance occurred because the air flow was quite near to the large opening area where the airflow was allowed to enter. This is due to the less of an interruption to the airflow when it enters the gap area between the two blades distributor.

“…The simulation results of 60 blades with 15° blade inclination by Tawfik et al, [7] were taken for validation. To optimize the current model of current fluidization systems the statistical analysis can be used in this study, the optimum configuration and parameter will be determined as previous study have been done [16][17][18].…”

Flowing gas in fluidized bed through selected inlet distributor may imparts a drag effect on the particles, would cause an increase in gas flow, that maybe sufficient to rearrange the particles movement. Thus, study on the airflow in a fluidization system through numerical analysis has been conducted to investigate the airflow distribution affected by new model distributor of twist blade distributor configuration. The present study would emphasis on computational procedure and parametric study via ANSYS Fluent before a detailed study on selected twist blade distributor are conducted. The selected parametric study on the twist blade distributor configuration whereby the twist blade angle (100°), horizontal inclination angle (15°), radial inclination angle (10°) and number of blades (60) was carried out. Therefore, the results of the studies that have been carried out meet the expected standards based on previous studies.

“…The statistical analysis may be employed in this research to optimise the present model of current fluidization systems. The optimal design and parameter will be identified, as in earlier studies [13][14][15].…”

Swirling Fluidized Bed (SFB) is a system that possess a plenum chamber and distributor air gap which leading up to dispersion of the airflow to the bed. The current SFB is in contrast with conventional fluidization systems whereby the effect of multi-stage through blades inclination angle (15°) and number of blades (60) was carried out. The simulation was used to compute and assess the performance outcomes of velocity distribution in a SFB. Therefore, the present study focuses on the numerical analysis procedure on the air flow distribution impacted by annular blade distributor arrangement in a Multi-stage SFB via ANSYS Fluent before a detailed study on selected variable would be carried out. As a consequence, the findings of the primary study that have been conducted are in line with expectations formed by earlier research.
