Abstract

In this case study, LION Corporation uses Particleworks to simulate fluid flow to improve the design of a new cap spout for its new HARETA brand of laundry detergent. The HARETA liquid laundry detergent contains a polymer to increase its viscosity. It has a non-Newtonian viscosity meaning that the liquid tends to be less viscous during the pouring process. Instead of using its traditional design method of creating 100 product prototypes using 3D printers, the design engineers, with Promotech’s cooperation, created a simulation of the new bottle cap spout design and compared it to a conventional product to improve the pouring and measuring performance of a dose of laundry detergent.

The simulation enabled the engineers to calculate the velocity gradient and observe its effect on the whole flow-down phenomenon.
