Computational Fluid Dynamics

Introduction

This continuum-based method is based on the solution of the complex set of mathematical equations describing the motion of a fluid. Using a multi-phase approach, gas-solid, liquid-solid and gas-liquid-solid flows can be treated.

Type of phenomena treated

Multi-phase CFD modelling of granular flows is appropriate when the solid particulate phase is secondary to the fluid (gas or liquid) phase. The particles can be dispersed through the fluid with a low volume fraction, such as in spray dryers. Alternatively, for higher solid volume fractions, the particulate phase can be treated as a continuum that inter-penetrates the fluid phase, such as in fluidized beds. CFD can be used to simulate a wide range of phenomena, including:

    • multiple-phase flows
    • porous media
    • turbulence
    • mixing, blending
    • mass convection, diffusion
    • thermal transport
    • ...

What you can get from CFD simulations

    • flow characteristics
    • pressure and temperature distributions
    • power draw
    • surface forces and wear rates
    • laminar and turbulent mixing rates
    • ...

CFD expertise

A large expertise in CFD has been gained through the study of a wide range of industrial applications. Commercial CFD software packages are used for this purpose.
