A mesoscale particle model (movable automata) was chosen to enable performant simulation of all relevant aspects of the system, including phase changes, plastic deformation and flow, interface phenomena, turbulence, etc. The physical system under study comprised two atomically flat surfaces composed of particles of different sizes and separated by a model fluid formed by moving particles with repulsing cores of different sizes and long-range attraction. The resulting simulation method was tested under a variety of particle densities and conditions. It was shown that the particles can enter different (solid, liquid, and gaseous) states, depending on the effective temperature (kinetic energy caused by surface motion and random noise generated by spatially distributed Langevin sources). The local order parameter and formation of solid domains was studied for systems with varying density. Heating of the region close to one of the plates could change the density of the liquid in its proximity and resulted in chaotization (turbulence); it also dramatically changed the system configuration, the direction of the average flow, and reduced the effective friction force.<\/jats:p>","DOI":"10.3390\/computation13070155","type":"journal-article","created":{"date-parts":[[2025,7,1]],"date-time":"2025-07-01T04:04:22Z","timestamp":1751342662000},"page":"155","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A Mesoscale Particle Method for Simulation of Boundary Slip Phenomena in Fluid Systems"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5410-6965","authenticated-orcid":false,"given":"Alexander E.","family":"Filippov","sequence":"first","affiliation":[{"name":"Department of System Dynamics and Friction Physics, Technische Universit\u00e4t Berlin, 10623 Berlin, Germany"}]},{"given":"Mikhail","family":"Popov","sequence":"additional","affiliation":[{"name":"Department of Artificial Intelligence and Information Systems, Samarkand State University, Samarkand 140104, Uzbekistan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0506-3804","authenticated-orcid":false,"given":"Valentin L.","family":"Popov","sequence":"additional","affiliation":[{"name":"Department of System Dynamics and Friction Physics, Technische Universit\u00e4t Berlin, 10623 Berlin, Germany"},{"name":"Center of Advanced Studies in Mechanics, Tribology, Bio- and Nanotechnologies, Samarkand State University, Samarkand 140104, Uzbekistan"}]}],"member":"1968","published-online":{"date-parts":[[2025,7,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"6830","DOI":"10.1103\/PhysRevA.41.6830","article-title":"Shear flow near solids: Epitaxial order and flow boundary conditions","volume":"41","author":"Thompson","year":"1990","journal-title":"Phys.
