i made a geometry of a food dryer to asses the air distribution along the length of dryer using design modeller. Air needs to distribute in drying chamber after passing through an air guider. I unite both drying chamber and air guider using Bolean tool and they act as fluid.
Food buckets + small round bodies (acting as fruits) lying in the drying cahmber have been subtratced from this fluid domain. i want to see the behaviur of air distribution and heat transfer from air to food items using ANSYS Fluent. I dont know how to assign the BC for heat transfer between incoming air and the bodies acting as food items. Plz do help, If somebody has tutorial regarding exchange of heat between two bodies.
