| Abstract: |
| Spiral plate heat exchanger is a traditional compact heat exchanger, and widely used in the occasion of the high heat transfer capacity requirements, such as waste heat recovery. In the situation of energy shortage and rapid development of heat transfer technology[1-3], cylindrical, elliptical and rhombic spiral pile-honeycomb heat transfer models are established[4-5]. The internal flow and heat transfer are simulated by using CFD software FLUENT15.0 and RNG k-ε turbulent model, and then the three models are analyzed. The results show that the secondary flow and vortex are induced again in the secondary honeycomb, which further increases the turbulence intensity of the fluid. The thickness of the boundary layer is reduced twice, and the heat transfer effect is better than that of the honeycomb spiral structure. The spiral pile-honeycomb model for the rhombus is better than the models of cylinder and ellipse in heat transfer performance. |
