“…In order to validate the heat transfer and fluid flow results, the problem has been solved for the the external flow problem on nuclear fuel element (Jahangeer et al [13] and Ramis and Jilani [14]) which is close to present work available in literature as shown Figure 3, having uniform and non-uniform heat generation term was analyzed. A fairly good agreement was obtained of the temperature distribution between their results and the present FVM code was obtained.…”

In modern electric vehicles the thermal stability problems associated with Lithium-ion (Li-ion) battery system is of major concern. Proper battery thermal management systems (BTMS) is required to ensure safety and efficient performance of battery cells. A realistic conjugate heat transfer and fluid flow analysis of Li-ion prismatic battery cell is performed. The flow of air as coolant, is laminar, flowing between the heat generating battery cells. The effect of few important working parameters like volumetric heat generation ( q), conduction-convection parameter (?cc), Reynolds number (Re), Aspect ratio (Ar), and spacing between the cells ( f) is investigated in this work. For the wide range of parameters considered, the temperature variations in battery cell and coolant is carried out. Focusing mainly on effect of Re and f, behavior of local Nusselt number (Nux), local friction coefficient (Cf, x), average Nusselt number (Nuavg), average friction coefficient (Cf, avg), maximum temperature, mean fluid temperature, heat removed from the lateral surface of cell are discussed. Nuavg increased with increase in Re but decreased with increase in f, whereas Cf, avg decreased with increase in Re and f. It is also found that their exists an upper and lower limit on Re and f above and below which the change in Cf, avg and Nuavg is negligible. Maximum temperature is significantly influenced at low Re and for all f. From the lateral surface of battery over which the coolant flows, more than 96% of heat generated in cell is removed.
