摘要 本文研究了存在于多孔介质中的Rivlin-Ericksen流体的Brinkman模型,对其在双固壁边界条件下加适当Coriolis力(即旋转)时热失稳的必要条件进行了理论分析和计算,结果充分表明了适当的旋转有抑制对流的作用。 In this paper, the Bivlin-Ericksen fluid according to Brinkman model in porous medium is studied.The necessary conditions of thermal instability with the Coriolis force (rotation) in the case of rigid-rigid boundaries are calculated and analyzed in theory, and the result indicates clearly that the appropriate rotation has an inhibiting effect on the convection of the system.
