Abstract

Wiper system is one of the driving safety systems for a vehicle. Most wipers operate together with a fluid washer and a motor pumps that supplies water from a tank to the windscreen. Conventional nozzles are usually used, but some designs use a fluidic oscillator to disperse the fluid more effectively. These various types of washer tube that have been used in automotive are washer T-tube design for Mitsubishi and Y tube design for Proton and Toyota. The main objective of this thesis is to modify the design of existing washer tube hose for three different washer tube of cars and compare the fluid flow properties by using Computational Fluid Dynamics (CFD) simulation. In order to minimize the eddy formation at the junction of washer tube, the existing junction of washer tube is replaced by a curvature junction. Washer tube hose models are designed by using Computer Aided Design (CAD) while fluid flow analysis by using CFD simulation that can save a lot of time without doing the actual experiment. By the end of this project, the results showed that the curvature junction proved can release the eddy forming a Y-junction but not at T-junction tube.
