Abstract

Numerical simulation is performed to investigate the vapor-liquid two-phase flow in axisymmetric channels using the particle model. Different thickness dirt layer is covered in the channel downstream region. Uniform heat flux is applied on one steel tube wall. Comparison of the simulated bulk temperature of the heated tube wall and that of temperature obtained from experiments shows that the difference is within 8%. In the simulations, the changes of the two-phase volume fraction, wall bulk temperature, pressure drop and heat transfer coefficient are obtained. Subsequent simulation results show that the heat transfer coefficient enhancement in channel without dirt blockage can be 1200% as that with dirt lockage thickness of 1.55mm. The results also show that the heat transfer performance varies with the volume fraction of the two-phase flow.
