- Abstract:
- Three periodic models with different installation angles of the blade baffle heat exchanger were established by the CFD analysis software Fluent. The installion angles were 30°, 45°, 60°, respectively. And the performance of heat exchanger with different installation angles was investigated. Results showed that in the diversion of the baffle, the shell-side flow became sideling flow, which could restrain the flow induced vibration effectively. The velocity of the fluid in the near wall region was higher than that of the central region. With the increase of the installation angle, the shell-side pressure drop decreased, the comprehensive performance of the heat transfer coefficient of the exchanger increased. When the installation angle was 30° the heat transfer coefficient was larger than the other two.
