| 摘 要： | 本文对缝隙式回热器在非稳态交交流动下的流动和换热问题做了二维的数值模拟,并重点对其在交交流动下的场协同问题做了计算与分析。数值计算表明,场协同原理作为指导强化对流换热的原则,同样可以指导交交流动下的换热强化。

| Abstract: | Numerical investigation of transient heat transfer of oscillating flow in gap regenerator was conducted for a 2-D parallel duct model. The transient heat transfer rate between gas and the solid wall, the integration of the convection term and the intersection angle between velocity and temperature gradient are presented as functions of time. It is found that the variation trend of the heat transfer rate, integration and the intersection angle with time are fully consistent with the field synergy principle. It thus demonstrates that the field synergy principle is also applicable to the transient situation and is helpful to develop techniques for enhancing transient heat transfer. |
