Analytical Performance Analysis of Cross Flow Louvered Fin Automobile Radiator

Abstract

The objective of the present paper is to propose an analytical model for calculating performance parameter of a radiator having rectangular tube with louvered fins. The theoretical effectiveness, heat transfer rate, outlet temperatures of both air and coolant are determined using effectiveness-NTU method. The coolant and air side pressure drop is also calculated. The proposed procedure is validated with experimetal results available in the literature and the GT model. It is found that the maximum deviation in the heat transfer rate calculated from proposed model is 10.97%, the coolant and air outlet temperatures is 2.75% and variation in pressure drop is about 3.29%.

Performance Investigation of Copper and Aluminium Radiators for Lower HP Tractor Engines

“…For the detailed comparison of copper and aluminium radiator, two radiators were tested on the same vehicle of different configurations (Table 1) Determination of heat transfer effectiveness is very complicated in the case of cross flow heat exchanger [5], [16]. The information regarding this type of flow or formulas have not been published and other analytical solutions are very difficult to use.…”

The Assessment of Electric Vehicle Storage Lifetime Using Battery Thermal Management System

“…To attest to the model validity, tests conducted in [38,39] compared a radiator-based liquid cooling system with the use of the NTU method with experimental results with great correlation. For a better understanding of the NTU method, a better discussion of the method can be seen in [37][38][39][40][41]. It is worth noting that these equations are directly affected by the fluid's properties at specific environmental and/or operational conditions.…”
