Accurate thermal systems’ modelling is dependent on the ability to model the air flow through the cooling pack for a range of transient operating conditions. Flowmaster Automotive’s Airside Systems Modelling packages enable you to optimise the interactions of close-coupled heat exchangers using automatic air flow path segmentation.
By integrating non-uniform air flow in the cooling pack design you can impose profiles for velocity, pressure coefficient and temperature. Through imposing loss coefficient profiles you can investigate non-uniform blockage of your heat exchanger.
A set of standard components come with the Airside package and include:
- Stagnation pressure source - Enter a measured or calculated cp distribution across the grille or at a single point. Automatically factor the cp distribution by the vehicle speed for accurate transient simulation.
- Three-way flap valve - Developed for HVAC systems to direct flow to different vents in the cabin, direct flow around or through the heater core, select between fresh outside air and recirculated air.
- Fan drives - Torque-limited viscous drive, Temperature-sensing viscous drive, Friction drive, Electric motor.
- HVAC blower - Suited to the modelling of a blower commonly found in cabin ventilation systems.
- Radiator shutter - Controls the amount of ram air entering the radiator or heat exchanger. Used mainly on heavy commercial vehicles.
- Fan component - Commonly used in the modelling of the complete cooling pack.
