Aerodynamics Simulation: Coupling CFD with MBD, FEA and 1D-System Simulation

FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization

Aerodynamics is a common application of CFD and one of the Enteknograte team core areas of expertise. Studies can cover the full speed range of low speed, transonic, supersonic and hypersonic flows as well as turbulence and flow control. System properties such as mass flow rates and pressure drops and fluid dynamic forces such as lift, drag and pitching moment can be readily calculated in addition to the wake effects. This data can be used directly for design purposes or as in input to a detailed stress analysis. Aerodynamics CFD simulation with sophisticated tools such as MSC Cradle, Ansys Fluent and Siemens Star-ccm+ allows the steady-state and transient aerodynamics of heating ventilation & air conditioning (HVAC) systems, vehicles, aircraft, structures, wings and rotors to be computed with extremely high levels of accuracy.
CFD simulation offers the ability to conduct comprehensive, automated, multi-point optimization of designs. This process allows our engineers to optimize a design to a given set of performance parameters and can be used to minimize drag, or maximize mass flow or lift forces to given targets. Enteknograte engineering team is providing effective solutions in optimizing lift to drag ratios and balancing overall performance with size.

External Aerodynamics Simulation

From the design of a hyper car to regular family-SUV type cars aerodynamics play a crucial role, where Enteknograte engineering team can support you throughout the entire process using sophisticated CFD tools such as Siemens Star-ccm+ and Ansys Fluent.

For every operating condition of the vehicle aerodynamics there is a key part where performance drives the vehicle shape. Key aspects analysed in external aerodynamics include:

  • Drag evaluation: Pressure, cooling
  • Cooling efficiency: Air leakage
  • Downforce optimization: Front end air flow

Internal Flow Aerodynamics Simulation

If your problem is an “internal flow” case, whereas the fluid is confined by walls in every direction, most important aerodynamic quantities involves pressure loss, friction, local velocity and turbulence. These quantities can be very well simulated and predicted for your product, way before it gets manufactured. This means cost and time savings for you.

Examples for internal flow aerodynamics applications:

  • pipe flows
  • duct flow in HVAC applications and building air-conditioning
  • turbomachinery
  • diffusors
  • nozzles
  • sudden contractions and expansions
  • valves
  • fittings
  • elbows in piping systems
  • heat exchangers
  • general industrial flows

CFD method is used to analyze and solves the problem related to Fluid Flows, computers are required to formulate the mathematical expression of interaction between liquid and gas with defined boundaries. It has wide applications in industries like automotive, part of Defense, Electrical and physical science, and Energy. CFD gives realistic and predictive insight in to Flow patterns & Thermal contours that are intended to solve complex engineering problems.
