A comprehensive numerical analysis on the heat transfer process in the louvered fin heat exchanger was conducted. In this paper, the physical and mathematical models on the coupled conduction-convective heat transfer for the louver fin geometry were developed. The control volume-based finite element method (CVFEM) was employed to solve the problem numerically. The computed results revealed the flow structure and heat transfer in the geometry in detail. Compared with the empirical correlation of heat transfer and friction coefficients previously proposed, the computed results showed better agreement with the experimental results.
