Automotive

In Automotive industry, FlowVision is used for various simulation purposes ranging from well-known aerodynamics problems to extensive multi-phase and multi-physics problems such as tire aquaplaning or torque conversion in gearboxes.

  • Car Tire Aquaplaning. FlowVision’s unique FSI integration with ABAQUS allows for simulating 2-phase flow around rotating and elastic tire bodies. In such cases, effectiveness of tire tread patterns are compared to reduce the risk of hydroplaning and to increase skid-resistance.
  • Lubricant Dynamics (Gear-Boxes, Torque Converters, Oil Pumps, Bearings). FlowVision is highly capable of simulating advanced physics involved in lubricant dynamics of automobiles. 2-Phase flow with free surface tracking, rotating bodies, unique Gap model for extremely narrow clearances and 2-way coupled FSI simulations are among FlowVision’s special capabilities in this area.
  • Engine Cooling. FlowVision is completely suited for calculating conduction and convection heat transfer in stationary and moving parts of automobile engines.
  • Fuel Tank & Oil Pan Sloshing. FlowVision’s Extended VOF Method helps in simulating transient free surface tracking in sloshing problems.
  • Thermal Loading in Brake Systems. In order to ensure desired thermal performance of automobile brakes, FlowVision is used for simulating conduction and convection heat transfer mechanisms in cases such as interaction between brake disks and lining pad.
  • Gas Dynamics in Reciprocating & Rotary Engines. FlowVision’s moving body technology allows for defining any type of piston and valve movements uniquely including full closure of valves. Resultantly, all desired stationary and moving parts can be modeled in FlowVision to solve for physics of gas dynamics including injection and spraying.
  • Combustion & Thermal Loading in Engine Blocks. There are various combustion models with mass transfer in FlowVision and additionally, localized and time-based spark ignition regions can easily be defined.
  • Radiators & Oil Coolers. Radiator and oil coolers used in automobiles usually consist of very small and large number of parts which results in a crucial problem for CFD
  • External Aerodynamics. Air flow around a car is typically simulated for purposes such as drag minimization, down force maximization or driving stabilization. FlowVision solvers are highly accurate in predicting these phenomena and, in addition to that, importing geometries without simplifications and without manual work brings FlowVision one step forward in CFD simulations of car external aerodynamics.
  • Water Soiling. Thanks to FlowVision’s Extended VOF Method, water soiling on surfaces such as car windows are accurately simulated.
