Technalysis' Multiphase CFD (Computational Fluid Dynamics) Capabilities

Technalysis' multi-phase CFD capabilities can be divided into three prominent categories:

  1. System flow modeling
  2. Continuum flow modeling
  3. Discrete flow modeling

System flow modeling:

One Dimensional two-phase flow and heat transfer analysis.

Features:

  • Flow rate and pressure distribution
  • Phase change
  • Heat transfer with ambient
  • Coupled with air flow analysis inside the refrigerator


Application areas:

  • Refrigerant system analysis in refrigerator, air conditioning, etc.

Continuum flow modeling:

Three dimensional flow, heat transfer, concentration analysis

Features:

  • Level-set method to track interface between phases
  • Concentration analysis for mixing of phases
  • Phase change
  • Space charge behavior
  • Particle tracking

 

Application areas:

  • Casting, solidification, melting, condensation, evaporation, free surface
  • Mixture of gas/liquid, liquid/liquid
  • Binary mixing
  • Developer charge and mixing

Discrete flow modeling:

Three dimensional flows of particles under different forces.

Features:

  • Internal contact
  • Electrostatic, Magnetic and Gravitational forces
  • Varied particle size and shape
  • Charge and temperature analysis

Application areas:

  • Bulk material handling process and equipment design
  • Pharmaceutical tablet coating
  • Mixing of pharmaceutical molecule with binder
  • Charging of toner

Combination of Continuum and Discrete flow modeling:

Coupled three dimensional continuum flow and discrete flow analysis.

Features:

  • Transfer of mass, momentum and heat between fluid and particles
  • Inter-particle and fluid-particle interactions

Application areas:

  • Vacuum frying of food
  • Fluidized bed
  • Sedimentation
  • Condensation/Evaporation of water droplet
  • Bubble/Droplet mixing with fluid
  • Emulsion
