Abstract
The flow of non-Newtonian nanofluids (NNFs) within a lithium-ion battery coupled to a solar cooling system (Li-iBCS) is investigated in this paper. A capillary Li-iBCS is put on the anode and cathode of a pouch lithium battery, which is made up of three pieces. A constant velocity and temperature water-CMC/CuO NNFs flow enters the system and departs after cooling the cathode and anode surfaces. The flow of the NNFs is laminar, and the governing equation for the NNFs and batteries is solved using the finite element technique. According to the research, increasing the fluid velocity in the Li-iBCS reduces the battery average temperature and causes the fluid to leave at a lower temperature. Furthermore, the FOM and heat transfer coefficient are increased when the volume % of nanoparticles (NPs) is increased and the average battery temperature is reduced. The maximum amount of FOM (1.36) occurs at a velocity of 0.1 m/s and a volume percentage (VOPs) of 3%. The minimum amount of FOM (1.01) takes place at velocity of 0.5 m/s and VOP of 0.5%.
