RESEARCH HIGHLIGHTS:

Detachment of particles from droplets

The force applied to the particle adsorbed on a surface of a fluid droplet or bubble can be expressed in an analytical form as a function of the displacement of the particle from its equilibrium position.

Publications:

Dilatational viscosity

Effective dilatational viscosity of particle-laden fluid interfaces can be expressed in an analytical form in the limits of small and large surface concentrations of the particles.

Publications:

Bulk viscosity

Account of many-body inter-atomic interactions in simple fluids is necessary for accurate description of their bulk viscosity, in contrast with other transport properties.

Publication:

Fluids on curved surfaces

The equation of state of hard-disk fluids on curved surfaces depends upon the gaussian curvature of the surface. This dependence contributes to the value of the saddle-splay modulus of particle-laden fluid interfaces.

  • Lishchuk, EPL (2009) [doi] [pdf] [arxiv]

Surface tension at nanoscale

Finite-size effects significantly influence the interfacial tension of planar vapour-liquid interfaces.

Summation of dipolar interactions

The Lekner method for calculation of electrostatic interactions in periodically replicated simulation cells can be extended to quasi-two-dimensional systems of particles with dipolar interactions. This technique is sometimes referred to as “Lekner–Lishchuk summation”.

Publication:

Nematic–surfactant–isotropic interfaces

The spectrum of surface waves at a monomolecular surfactant film between an isotropic liquid and a nematic liquid crystal exhibits rich structure.

  • Lishchuk, Chem. Eng. Comm. (2009) [doi] [pdf]

COMPUTER MODELLING HIGHLIGHTS:

Molecular simulation software

In 1999–2002 I initiated the development of the ms* series of molecular simulation codes. One of them (ms2) became so successful that it now lives a life of its own.

Publications:

  • Deublein et al., Comp. Phys. Comm. (2011) [doi]
  • Deublein et al., Chem. Eng. Tech. (2012) [doi]

Multi-component lattice Boltzmann

The algorithm known as “Lishchuk method” is implemented within STFC Daresbury Laboratory′s simulation package DL_MESO.

The algorithm is described in the paper:

  • Lishchuk et al., Phys. Rev. E (2003) [doi]

Stress corrosion cracking

The hybrid Cellular Automata Finite Element (CAFE) model is capable of predicting the evolution of pitting corrosion damage during the pre-crack stages of environment assisted cracking.
