a study on thermodynamic models for simulation of 1,3 butadiene purification columns
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
Entropic Lattice Boltzmann Method for Large Scale Turbulence Simulation
Recently, a minimal kinetic model for fluid flow, known as entropic lattice Boltzmann method, has been proposed for the simulation of isothermal hydrodynamic flows. At variance with previous Lattice Boltzmann methods, the entropic version permits to describe the non-linear dynamics of short scales in a controlled and stable way. In this paper, we provide the first numerical evidence that the en...
متن کاملA Novel Algorithm for Fluid Simulation Using Incompressible Turbulence Function
In this paper, we present a novel algorithm for simulating fluids at high resolution quickly. Instead of solving the Navier-Stokes equations over a highly refined mesh, we only require a low grid resolution to resolve the underlying base flow. We then use a novel incompressible turbulence function and compute transport of turbulent energy using a complete model, which generate accurate producti...
متن کاملNumerical simulation of continuum models for fluid-fluid interface dynamics
This paper is concerned with numerical methods for twophase incompressible flows assuming a sharp interface model for interfacial stresses. Standard continuum models for the fluid dynamics in the bulk phases, for mass transport of a solute between the phases and for surfactant transport on the interface are given. We review some recently developed finite element methods for the appropriate disc...
متن کاملInternal combustion engines in cylinder flow simulation improvement using nonlinear k-ε turbulence models
The purpose of this paper is to studying nonlinear k-ε turbulence models and its advantages in internal combustion engines, since the standard k-ε model is incapable of representing the anisotropy of turbulence intensities and fails to express the Reynolds stresses adequately in rotating flows. Therefore, this model is not only incapable of expressing the anisotropy of turbulence in an engine c...
