The tubular heat exchangers are widespread in the oil industry, therefore, the numerical simulation of the flow around a tube bundle is important. In this article, the LES method is used to study heat transfer in a ten-row in-line tube bundle in cross-flow. LES Smagorinsky, LES WALE and LES WM techniques in the numerical simulation were used. The Reynolds number Re was 2400, and the Prandtl number Pr was 7.33. The streamwise spacing-to-diameter ratio of the tube bundle was 1.3, transverse was 2.6. The local heat transfer characteristics of the eighth row are compared with the experimental data. The best agreement with the experimental data was obtained using the LES WALE and LES WM techniques.
