Application of lattice Boltzmann method for studying interaction dynamics of parallel plane minijets

Abstract

Abstract In this work, the method of lattice Boltzmann equations was applied to simulate the systems of two and three parallel laminar plane jets. Simulation was carried out for different Reynolds numbers (Re = 20-200). For the case of two jets, the character of jet interaction has been determined to be, in general, non-stationary, but for small Re values, the process becomes stable due to the action of viscosity forces. For the case of three jets, the character of jets interaction is found to differ significantly from the case of two jets and is non-stationary even for small Re numbers.
