Numerical study on ventilation and thermal comfort of car seat
By referring to the parameters of ventilated seat in a car cockpit,a physical model of this seat was established.A layout of ventilation channels was designed.Mathematical modeling and simulation calculation on the proposed physical model of ventilated seat were conducted.The changes of pressure and velocity fields at three flow rates were obtained.The flow of cold air in the channels of seat was predicted using numerical simulation method.The flow field of ventilation channels in the seat was numerically calculated under different operating conditions.The outlet velocity and pressure distribution on the surface of porous seat plate was analyzed.Results indicate that the uniform airflow velocity distribution and reasonable pressure distribution on the surface of ventilated seat are achieved.No obvious high-pressure zone is existed.Combining with a cooling fan,this seat has good ventilation effect and can effectively improve the thermal comfort of human body.
