摘要

The large-scale vortices shed from a cylindrical object as a vortex generator can be used to enhance heat transfer in a heat exchanger[1]. Furthermore, the large-scale vortices induce secondary vortices on the walls of a heat exchanger, which also play a positive role in heat transfer enhancement.When a square cylinder is inclined with respect to the direction of the main flow, flow separation may occur at various pairs of the corners of the square, resulting in drastic change of key flow parameters such as force coefficients and Strouhal number (St). The main objective of the current numerical investigation is to enhance heat transfer capacity in laminar channel flow (Fig. 1) by taking advantage of the diverse flow characteristics of the vortices generated by an inclined square cylinder. Attempt has been made to find the optimal inclination angle which yields the maximum heat transfer enhancement. A possible physical mechanism for the enhancement is also discussed.
