Spray drying is often used for manufacture of LFP cathode powder as the method results in particles of uniform size and with favorable structure. Analyzing the heat and mass transfer characteristics during a spray drying process through experiments is expensive and involves tedious measurements and methods.

spray drying is measured by the amount of water evaporated. Evaporation is defined as the difference between inlet and outlet temperature, or T, in the dry-ing air. The larger the T, the greater the capacity of the spray dryer. The goal in optimizing a spray dryer's capacity is to increase T by raising the inlet tempera-
