•Numerical analysis of a battery pack containing cylindrical and plate lithium-ion battery cells in an air duct is utilized.•Investigation on the impact of two alternative oval and triangle splitter damper forms on the BRK's temperature and the incoming air.•Increasing the length of the splitter damper in both triangular and oval shapes of the splitter damper, causes the heat transfer coefficient to increase.•The minimum temperature of the BRK was less for the oval shape than the triangular shape of the splitter damper. This paper simulates a lithium-ion battery pack (BRK) with cylindrical and plate batteries in an air duct. The batteries are arranged in rows of cylinders and plates in the BRK. A splitter damper is used at the air inlet and outlet in the duct. This study was performed in a laminar airflow by changing the length of the splitter damper from 0.2 to 0.5 m, for both oval and triangular shapes of the splitter damper. Effects of various splitter damper settings on the BRK temperature, output air temperature, and heat transfer coefficient have been investigated. The BRK is simulated using COMSOL 6.0 software. According to the study's findings, the BRK greatest and lowest mean temperatures were measured along the 0.4 and 0.2 m of the splitter damper's triangular form, respectively. The heat transfer coefficient for the oval shape of the splitter damper was higher than the triangular shape of the splitter damper at all lengths of the splitter damper. The highest heat transfer coefficient is recorded in the oval form of a splitter damper with a length of 0.5 m.
