Water Saving Shower Head: Multi-iterative Design Incorporating Atomized Flow
Floor Location : M 069 N
Showers present society with a design opportunity to simultaneously improve functionality and decrease water usage, a critical area for improvement given that each Canadians adult use an average of 340 litres per day. Showers typically run at or near 9.5 litres per minute (LPM), the US legal maximum, accounting for 46% of total water consumption based on land use in the US. This project aims to create a shower that runs at a significantly lower LPM, effecting the result of a decrease in overall household water usage. A combination of water atomization, and the introduction of an air stream into the shower head, has the potential to produce the desired reduction in water consumption while simultaneously maintaining robust usage potential.
The atomization technique forces water into significantly small droplets, which increases surface area, however maintaining water pressure. The application of atomization technology to bathroom fixtures is quite recent, having been applied to just a few shower heads - including the "Nebia" ,which has not yet reached the consumer market. Nebia's design runs at 2.8 LPM, which is significantly lower than the legal maximum however, this project aims to deliver a greater water savings than the costly Nebia, in a shower head which can be delivered to the consumer at a reasonable price.
Design and simulations will first be conducted virtually, using Ansys Fluent software, on a custom i7 5930k computer build. A control test simulating flow of a standard shower head will be compared with the proposed virtual prototype. A multi-iterative virtual design process will be implemented , with the goal of transitioning to the manufacturing of a real-world prototype in time for the GVRSF.
* Create a functional shower head that will make use of water atomization, and the introduction of air into the device, ultimately achieving a LPM of 2.8 or lower with a mist-like consistency flow.
* Perform computational simulations of the flow patterns, focusing on areas such as pressure, volume, temperature, and flow rate
* Provide an enjoyable, aesthetically pleasing experience suitable to subjects with long or thick hair
* Complete multiple virtual design iterations prior to manufacturing the first real-world prototype.
