Nebia, a business startup, designed a new showerhead to transform the shower experience while saving water and energy. Because most of the cost of a shower is in heating the water, engineers were challenged to keep the user warm while reducing the amount of water needed. They leveraged ANSYS fluid dynamics to model the water flow through the shower to reduce pressure drop, maintain warmth and generate an excellent shower experience. Simulation was instrumental for this new company. It allowed it to quickly and cost-effectively test many versions of its product and deliver the showerhead to market.
