Yoomi is a rechargeable, BPA-free, self-warming baby bottle that warms baby's feed to the natural temperature of breast milk at the touch of a button. It incorporates an integral warming unit as the source of heat. The warmer contains sodium acetate, which undergoes an exothermic phase change (liquid-to-solid) when initiated. The milk flows along the channels of the warmer's external mantel, where it is heated to the correct temperature.
The lecture discusses technical challenges in designing a warmer that can heat the milk from 5 to 32 °C for the first drop flow rate of 200 ml/min and to maintain steady-flow conditions. It also presents CFD modelling techniques, which were used in all stages of the development process to improve the design, and to significantly reduce the development time and costs.
