具有广义记忆的粘弹性流动分析及其指数收敛到定常状态

Analysis of viscoelastic flow with a generalized memory and its exponential convergence to steady state

Yingwen Guo, Xiangcheng Zheng

摘要:

本文研究了一类具有广义记忆的粘弹性流动模型,在经典粘弹性流动方程的指数卷积核中引入了一个弱奇异分量。我们证明了解的适定性和正则性,并在此基础上证明了解指数收敛到定态。该模型是经典粘弹性流动方程的推广,增加了一个以弱奇异核幂为特征的维数,所得结果为求解该方程及其稳态的数值方法设计提供了理论支持.

英文摘要:

We investigate a viscoelastic flow model with a generalized memory, in which a weak-singular component is introduced in the exponential convolution kernel of classical viscoelastic flow equations that remains untreated in the literature. We prove the well-posedness and regularity of the solutions, based on which we prove the exponential convergence of the solutions to the steady state. The proposed model serves as an extension of classical viscoelastic flow equations by adding a dimension characterized by the power of the weak-singular kernel, and the derived results provide theoretical supports for designing numerical methods for both the considered equation and its steady state.
