Numerical treatments for large eddy simulations of liquid–liquid dispersions via population balance equation

چکیده
In this work, we employ the two-fluid model under large eddy simulations (LES) framework to investigate liquid–liquid dispersions in stirred tanks. The population balance equation was solved by one primary and secondary particle method, which proven as identical one-node quadrature method of moments. First, Aiyer's break-age kernel investigated for its capability context chemical tank applications [Aiyer et al., “A simulation polydisperse droplet evolution,” J. Fluid Mech. 878, 700–739 (2019)]. Second, two new methods were proposed handle consistency problem boundedness problem. These numerical problems shown our previous studies but had never been discussed detail. Three test cases launched, results showed that implementation ensures moments' boundedness. inconsistency also treated properly. predicted diameter agrees well with experiments. Meanwhile, phase segregation observed unsteady Reynolds-Averaged Navier–Stokes disappeared when a LES turbulence employed.

Numerical Solution of Heun Equation Via Linear Stochastic Differential Equation
In this paper, we intend to solve special kind of ordinary differential equations which is called Heun equations, by converting to a corresponding stochastic differential equation(S.D.E.). So, we construct a stochastic linear equation system from this equation which its solution is based on computing fundamental matrix of this system and then, this S.D.E. is solved by numerically methods.

The oodlesDST code is based on OpenFOAM software and performs Large Eddy Simulations of turbulent fluid flows. The code contains a number of specialized subgrid scale turbulence models and wall models. This report describes these models in sufficient detail to allow a new user of the code to make informed decisions regarding the use of these models for particular applications. An overview of th...
متن کاملWall-layer Models for Large-eddy Simulations
■ Abstract Because the cost of large-eddy simulations (LES) of wall-bounded flows that resolve all the important eddies depends strongly on the Reynolds number, methods to bypass the wall layer are required to perform high-Reynolds-number LES at a reasonable cost. In this paper the available methodologies are reviewed, and their ranges of applicability are highlighted. Various unresolved issues...
