Numerical Simulation of Liquid Atomisation

The focus of this study was to investigate the spray characteristics and atomization performance of gasoline fuel (G100) and ethanol fuel (E100) in a high pressure chamber. The overall spray and atomization characteristics such as an axial spray tip penetration, spray width, and overall SMD were measured experimentally and predicted by using ANSYS Fluent. The development process and the appearance timing of the vortices in the test fuels were very similar. Moreover, the increased injection pressure induced the occurrence of a clear circular shape in the downstream spray and a uniform mixture between the injected spray droplets and ambient air. The axial spray tip penetrations of the test fuels were similar, while the spray width and spray cone angle of G100 were slightly larger than the other fuels. In terms of atomization performance, the E100 fuel among the tested fuels had the largest droplet size because E100 has a high kinematic viscosity and surface tension.

Design and Fabrication of Adjustable Side Table

This project is about designing and fabricating the adjustable side table. This project involves the process of designing the side table by considering the shape and also the ergonomic factor for people to use. After the design has completed, it was transformed to its real product where the design is used for guideline. In this project, turret punch machine, bending machine, MIG welding machine and drilling machine are being uses. The method used is SolidWork software, AutoCad software and TOP300R software. After all the process had been done, this side table may help us to understand the fabrication and designing process that involved in this project. -Author.
