The onset of thermal convection in a uniformly rotating and horizontally isotropic bi-disperse porous medium, taking into account the Vadasz term, is investigated. Via linear instability analysis, it has been proved that the Vadasz term allows the onset of convection via an oscillatory state but does not affect convection via a stationary motion.

Vadasz 项、各向异性和旋转对双分散对流的影响

考虑到 Vadasz 项，研究了均匀旋转和水平各向同性双分散多孔介质中热对流的开始。通过线性不稳定性分析，已经证明 Vadasz 项允许通过振荡状态开始对流，但不会通过静止运动影响对流。
