Estimates for stress concentration between two adjacent rigid inclusions in Stokes flow
Haigang Li, Longjuan Xu
In this paper, we establish the estimates for the gradient and the second-order partial derivatives for the Stokes flow in the presence of two closely located strictly convex inclu…
On higher regularity of Stokes systems with piecewise Hölder continuous coefficients
Hongjie Dong, Haigang Li, Longjuan Xu
In this paper, we consider higher regularity of a weak solution to stationary Stokes systems with variable coefficients. Under the assumptions that coefficients and d…
Stress blow-up analysis when suspending rigid particles approach boundary in 3D Stokes flow
Haigang Li, Longjuan Xu, Peihao Zhang
The stress concentration is a common phenomenon in the study of fluid-solid model. In this paper, we investigate the boundary gradient estimates and the second order derivatives es…
Stress blow-up analysis when a suspending rigid particle approaches the boundary in Stokes flow: 2D case
Haigang Li, Longjuan Xu, Peihao Zhang
It is an interesting and important topic to study the motion of small particles in a viscous liquid in current applied research. In this paper we assume the particles are convex wi…
The interaction between two close-to-touching convex acoustic subwavelength resonators
Haigang Li, Yan Zhao
The Minneart resonance is a low frequency resonance in which the wavelength is much larger than the size of the resonators. It is interesting to study the interaction between two a…
