high-speed water sheet on a contoured ramp. Voltus Industries' design is novel because it is a floating platform_x000D_
designed for off-shore locations in lakes. While the off-shore design provides flexibility for use in camps,_x000D_
beaches, and other recreational locations, it also imposes environmental and ecological constraints. An axial_x000D_
pump draws water through an intake plenum and passes it through a special nozzle to produce the water sheet._x000D_
After flowing over the ramp, the water returns to the lake. This design requires a large uptake of lake water,_x000D_
which has negative ecological and environmental impacts. This research will minimize the ecological impacts_x000D_
of the platform and decrease the amount of water uptake from the lake by simulation-based optimization of the_x000D_
platform's flow configuration. Computational fluid dynamics simulations of the water flowing through the_x000D_
pump, nozzle, and ducting will be employed to identify the configuration that minimizes the energy losses,_x000D_
ensures suitable uniformity of the water sheet, and minimizes the rate of water uptake from the lake. The_x000D_
production of vapor bubbles in low-pressure regions inside the pump--referred to as cavitation--must be_x000D_
avoided to ensure high reliability and low maintenance of the platform. Therefore, cavitation prediction models_x000D_
will be developed and implemented into the flow simulations. The research will ensure that the off-shore_x000D_
platform has a minimal impact on the local environment while also ensuring it is technically and economically_x000D_
