CFD is the virtual analysis of the dynamics of fluid flow. Additionaly the physics of heat transfer is taken into account as there is a strong coupling to the fluid flow character. (Some theory)

CFD is capable of handling several different physical phenomena, ranging from basic to more complex ones. Examples are laminar flow, transition, vortex dynamics, turbulence, flow separation, diffusion, convection, radiation and conduction.


Typical practical applications featuring, one or more, of these phenomena are:


  1. Pressure loss and flow distribution in duct and pipe systems.
  2. Aerodynamical performance for different type of vehicles and systems.
  3. Fluid and solid heat transfer, including radiation, for a variety of different applications (Thermal Management).
  4. Human and environmental comfort (ventilation, thermal and draught control).
  5. Mixing processes.
  6. Fan and pump performance.

Thermal Management constitutes a major focus area within CFD analysis. More information can be found under: Demos


In terms of engineering industries and branches the following ones can be mentioned (demo case within paranthesis):


Ground vehicle industry (MC-X10, MC-X11, MC-X12)

Typical studies are on the flow behavior around the vehicle. Flow distribution and cooling studies of encapsulated battery packs. Thermal effect on the surroundings from the exhaust systems. Cooling system and fan concept performance. Air intake and duct design. Engine compartment cooling. Driver's compartment and HVAC studies. Combined aerodynamical and cooling system / air intake studies on race cars. Performance of spoilers and wings.


Aeroplane industry (MC-X20, MC-X21)

External flow behavior of low speed to subsonic airplanes. Performance of body, wings, rudders, elevators and air intakes. Air intake, typically, also in combination with internal flow domains.


Marine industry (MC-X30, MC-X31)

Within the marine industri aerodynamic and hydrodynamic simulations are conducted. The aerodynamic simulations include human comfort on-board open or semi-open roof yachts and boats, ventilation aspects on-board boats and ships and exhaust gas studies. The hydrodynamic simulations include water resistance, wake studies, propulsion performance, and rudder / hydrofoil performance.


Building and city simulations (MC-X40, MC-X41)

Study of the ventilation and heating/cooling of rooms and buildings, including the effect on and from humans. Wind simulations around buildings and in cities and the effect from pressure distribution on windows and ventilators.


Process industry (MC-X50, MC-X51)

Pressure loss and flow distribution studies of gas/liquid duct/pipe systems. Particle mixing properties in gas/liquid flows. Heating and cooling processes.


Electronic industry (MC-X60, MC-X61)

Simulations of fluid flow in enclosed systems without or, mainly, with heat transfer. Typical applications are ventilation and cooling of electronic enclosures, such as computer racks, and components.


General industry (MC-X70, MC-X71)

Simulations of various kinds of applications, such as stationary large scale heat exchangers.
