Abstract

The drying cabinet had functioned as a storage hot air from the solar collector. There were some trays inside the drying cabinet. This paper had many purposes to predict air vector velocity and air temperature distribution inside the drying cabinet. It was done by simulation. It used computational fluid dynamics method with some setting such as the SIMPLE algorithm, k-epsilon realizable as a viscous turbulent model. The air inlet temperature was 323 K with a velocity of 0.1 m/s and 303 K for ambient temperature. It was simulated in a transient condition with time step 0.01 seconds. The velocity vector and temperature distribution were plotted at 4 seconds, 8 seconds, 16 seconds, and 32 seconds. The result showed tray in the bottom corner was the optimum tray. It was because of the position near to the inlet section or hot source with a maximum air temperature 322.6 K. It was also proved by air velocity streamlines that form big vorticities in the tray surface. At 32 seconds, air temperature distribution was already mixed and at the time the velocity vector reattachment formed. Its signed air temperature could be uniform if the number of iterations was increased.
