A new device for air lubrication called the Winged Air Induction Pipe (WAIP) is studied in the present work. The device, which consists of an angled hydrofoil, uses the low-pressure region produced above the hydrofoil as a ship moves forward. The low pressure drives the atmospheric air into the water at certain velocities when the pressure is negative compared to atmospheric pressure. A computational fluid dynamics approach is presented in the study of the effect of the hydrofoil clearance of the Winged Air Induction Pipe on the drag reduction experienced by the plate to which the WAIP is attached. The well-known 'volume of fluid' model and k- SST (shear stress transport) turbulence closure model were used in the 2D numerical simulation in ANSYS Fluent. The numerical simulation was conducted with different hydrofoil clearance and angle of attack configurations, and the effects of these parameters on total drag force and drag reduction are reported. The reduction of drag force is found to increase by about 10% compared to the bare plate configuration.
One of the positive impacts of the issuance of Law on the Government of Aceh Number 11 of 2006 is the formation of a strong foundation to form specific regulations under it, and one of them is in the field of education. Strong regulations make Aceh able to get a large fiscal capacity in building education in Aceh. However, at the practical level, the large budget in the field of education has not been directly proportional to the quality of existing education. This study aims to see to what extent the existing special autonomy funds have been able to improve the quality of education in Aceh. Management theory is used as a focus in analyzing this issue. Qualitative research with a strong data-based literature review approach can be accounted for as a method in this research. The result of this research is that the budget allocation management of the special autonomy fund for education in Aceh is still not effective. This is because there are still many activities carried out that have not been fully targeted, weak coordination and cross-sectoral cooperation, lack of long-term quality training. Coupled with the lack of creative programs implemented in supporting the achievement of improving the quality of education in Aceh. Therefore, it is necessary to have proper management and close cooperation between the Aceh government and all relevant stakeholders in order to jointly improve the quality of education in Aceh.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
