Name of the project: Micro- and nanoscale dynamics of disperse systems

Strategy for Scientific and Technological Development Priority Level: б

Goals and objectives

Research directions: Mathematics and mechanics

Project objective: Fundamental problems of micro- and nanoscale dynamics of fluids relevant for solving applied tasks of ail and gas industry, microindustry and biomedicine

The practical value of the study

  • We have solved problems of high computational complexity using high-performance clusters: modeling dynamics of bubbles in fluids, detailed research of their properties during movement and contact with surfaces, modeling movement of a large number of drops of emulsion, including in microchannels of arbitrary shape, computation and research of rheological properties of emulsions; study of features of formation of vortices during flow of viscous liquid and dynamics of deformable drops in microchannels with variable cross-sections
  • Our researchers have experimentally studied dynamics of bubble fluids under impact of ultrasound, features of behavior of emulsions under impact of electric field, properties of thin films on surfaces of hard substrates using atomic force microscopy, as well as investigated properties of surface nanobubbles also using atomic force microscopy. The Laboratory also investigated formation of hollows during production of fiber polymer composites.

Education and career development:

  • 7 candidate dissertations have been defended
  • Two scientific workshops have been conducted.
  • The Laboratory has developed lecture courses: «Solving applied tasks using boundary element method», «Research of the fast multifield method in linear algebra», «Programming for heterogeneous CPU/GPU architectures. Main CUDA technologies».
  • Our researchers have published 10 methodological guidebook.
  • We have compiled the program of the course «Methods of modern physical experiments. Atomic force microscopy».

Organizational and structural changes: On the grounds of the laboratory we have created a heterogeneous computational cluster with 4 computation nodes each of which is equipped with two universal processing units (CPUs) and 4 graphics processing units (GPUs). Theoretical peak performance for single precision is 26 Tflops and 11 Tflops for numbers with double precision.
