Active particles in geometrically confined viscoelastic fluids

We experimentally study the dynamics of active particles JOIGEL MEDIUM (APs) in a viscoelastic fluid under various geometrical constraints such as flat walls, spherical obstacles and cylindrical cavities.We observe that the main effect of the confined viscoelastic fluid is to induce an effective repulsion on the APs when moving close to a rigid sur

Developing drought impact functions for drought risk management

Drought management frameworks are dependent on methods for monitoring and prediction, but quantifying the hazard alone is arguably not sufficient; the negative consequences that may arise from a lack of precipitation must also be predicted if droughts are to be better managed.However, the link between drought intensity, Demi Tasse Spoons expressed

FFT-based interface decohesion modelling by a nonlocal interphase

Abstract In this paper, two nonlocal approaches to incorporate interface damage in fast Fourier transform (FFT) based spectral methods are analysed.In FFT based methods, the discretisation is generally non-conforming to the interfaces and hence interface elements cannot be Swarovski Pearls used.This limitation is remedied using the interfacial band
