STAR-CCM+ offers different models for cabin simulations as follows:
Thermal Comfort Simulation
STAR-CCM+ includes a human thermo-physiological model called Thermal Comfort Model (TCM) that accounts for thermal inertia, blood circulation, heat exchange (convection, conduction, radiation), vapor exchange (perspiration, breathing) and computer body temperatures and vapor loss/gain. Simulations can either be steady or transient.
Windshield Visibility Modeling
Cabin comfort doesn’t just include the thermal comfort of the occupants but also comfort in handling the vehicle inside the cabin.
STAR-CCM+ provides deice/defog models that can simulate the effectiveness of the HVAC system and the wipers for deicing and defogging on windshields and head/tail lamps in harsh climates.
These models have been implemented in collaboration with an industry partner and are available through the Thin Film model.
HVAC design is critical to understand the air flow distribution inside the cabin for comfort. In addition, HVAC noise affects cabin comfort significantly and simulation of the aeroacoustics of HVAC systems helps design quieter, comfortable cabins.
STAR-CCM+ offers an automatic HVAC workflow through a Java wizard that minimizes user interaction for HVAC analysis and frees up engineer time for in-depth engineering design and analysis.
