You are to model the cooling of cheese that is packaged in
cartons that are 500 mm long, 350 mm wide, and
200 mm high that sits on shelves made of an open steel mesh.
The cheese is initially at 50°C, and air at 5°C is blown over the
cartons to chill them. Experiments have determined that the airflow
over the cartons is turbulent with velocities of 5 m/s over
the top and bottom of the cartons, 4 m/s along the sides of
the cartons, and 0.3 m/s at the front and back of the
cartons.
the properties of cheese are to be taken as;
ρ 1130 kg/m3
k 0.35 W/m.K
cp 2525 J/kg.K
α 1.2267×10−7 m2/s
Calculate the heat transfer coefficients for each axis of the
package.
