Abstract
This research provides a fundamental study of the fluid mechanics of an automobile washer spray system from the reservoir to the windshield. A computational model is developed that specifies the strike location of the washer spray on the windshield. The model is useful to designers as an initial locator for nozzles, thus reducing wind-tunnel and road test time. A new algebraic model predicting the frequency and exit velocity of fluidic devices is successfully developed. It is generated by applying design of experiment and statistical regression analysis on a set of computational experimental data. The two phase flow (air and washer liquid) is modeled using the source panel method for the air flow and Newton’s Second Law to track the spray droplets.
The numerical scheme is designed to simplify the complexity of the two-phase flow analysis and is thus computationally economical. The computational results have been compared with experimental tests. In general, good qualitative and quantitative agreement is obtained.
This work is a pioneering effort in simulating the complexities associated with the droplet trajectory in automotive washer spray. Another unique aspect of this study is the use of design of experiment techniques with numerical as opposed to physical experiments.
